Functional Blood Chemistry Analysis (FBCA)

Functional blood chemistry analysis is a cutting-edge approach to assessing your blood test results and relevant functional blood test ranges.  This comprehensive lab result interpretation method goes beyond traditional blood work by providing a more detailed look at how different systems in the body are functioning – and what may be driving your symptoms. 

By examining specific biomarkers and patterns, and working with a nutritionist blood test expert, you can gain valuable insights into your overall health, identify potential deficiencies or imbalances, and develop targeted nutritional interventions to help you with your symptoms.   


blood testing and functional blood chemistry analysis reporting

So your blood test has come back normal? And yet you feel everything BUT normal. The GP has run through your blood panels and most are in range with the odd bio-marker labelled as High, or Low. 

The GP is happy with your result and tell you to “see how it goes”. 

See how what goes? 

You still:  

  • are tired with low energy 
  • have digestive disorders
  • have allergies
  • have Painful joints
  • have thyroid issues
  • have sleep disturbances
  • have skin problems
  • have anxiety / depression
  • have high blood pressure
  • have sex hormone dysfunction
  • have cognitive impairment

Yet your blood test results come back as “Normal”


Reference ranges vs optimal ranges

The issue with “normal” reference ranges is that they’re based on averages from the general population, not necessarily what’s best for maintaining good health. 

We all know that people are getting sicker and sicker don’t we? So if we have a population that is becoming sicker over time – the averages for these reference ranges will also change won’t they? These reference ranges are often too broad to catch health issues early on, before they become serious problems.  

We need to know the “optimal” range needed, backed by scientific evidence, showing that being within these ranges would help us to become healthy.  

Our approach to blood testing using functional blood chemistry analysis software focuses on how your body is functioning, rather than just looking for signs of disease. 

We use ranges based on optimal health rather than what’s considered “normal” for the population. This means we have a narrower “Functional Physiological Range” that helps us spot when something isn’t quite right in your body’s systems before it turns into a bigger issue – ie disease.

Leave behind the confusion of interpreting blood test results.  By working with our qualified Nutritional Therapist (MSc) and using our bespoke Functional Blood Chemistry Analysis software you can find out what is really going on with your blood, identify potential nutrient deficiencies, system imbalances and detect potential health trends before they escalate.

A comprehensive functional blood chemistry analysis is designed to answer 4 pivotal questions:

Is Dysfunction Present?

What are the underlying causes?

What tailored interventions are needed? 

When has the function been restored? 

normal blood test results rather than optimal


Your blood test results will show whether or not an individual biomarker is outside of the optimal range and/or outside of the clinical lab range. Some biomarkers in the Blood Test Results Report that are above or below the optimal or standard range will be hyperlinked into the “Out of Optimal Range Report”, (the red arrow on the picture) so you can read some background information on those biomarkers and why they may be high or low.

Glucose Metabolism

The Hemoglobin A1C test measures the amount of glucose that combines with hemoglobin to form glycohemoglobin during the normal lifespan of a red blood cell, which is about 120 days. The amount of glycohemoglobin formed is in direct proportion to the amount of glucose present in the bloodstream during the 120-day red blood cell lifespan. In the presence of high blood glucose levels (hyperglycemia) the amount of hemoglobin that is glycosylated to form glycohemoglobin increases and the hemoglobin A1C level will be high. Hemoglobin A1C is used primarily to monitor long-term blood glucose control and to help determine therapeutic options for treatment and management. 

Insulin is the hormone released by the pancreas in response to rising blood glucose levels and decreases blood glucose by transporting glucose into the cells. Often people lose their ability to utilise insulin to effectively drive blood glucose into energy-producing cells. This is commonly known as insulin resistance and is associated with increasing levels of insulin in the blood. Excess insulin is associated with greater risks of heart attack, stroke, metabolic syndrome, and diabetes. 

Kidney Health & Electrolytes

Sodium is an important blood electrolyte and functions to maintain osmotic pressure, acid-base balance, aids in nerve impulse transmission, as well as renal, cardiac, and adrenal functions. Increased sodium is most often due to dehydration (sweating, diarrhea, vomiting, polyuria, etc.) or adrenal stress. Decreased sodium levels are associated with adrenal insufficiency and edema. 

Potassium is one of the main electrolytes in the body. Due to the critical functions of potassium for human metabolism and physiology, it is essential for the body to maintain optimal serum levels even though a small concentration is found outside of the cell. Potassium levels should always be viewed in relation to the other electrolytes. Potassium concentration is greatly influenced by adrenal hormones. As such, potassium levels can be a marker for adrenal dysfunction.

Chloride plays an important role in human physiology. The amount of serum chloride is carefully regulated by the kidneys. Chloride is involved in regulating the acid-base balance in the body. Increased levels are associated with metabolic acidosis and decreased levels are associated with metabolic alkalosis. Chloride is an important molecule in the production of hydrochloric acid in the stomach so decreased levels are associated with hypochlorhydria.

BUN or Blood Urea Nitrogen reflects the ratio between the production and clearance of urea in the body. Urea is formed almost entirely by the liver from both protein metabolism and protein digestion.The amount of urea excreted as BUN varies with the amount of dietary protein intake. Increased BUN may be due to increased production of urea by the liver or decreased excretion by the kidney. BUN is a test used predominantly to measure kidney function, where it will be increased. An increased BUN is also associated with dehydration and hypochlorhydria. A low BUN is associated with malabsorption and a diet low in protein.

Creatinine is produced primarily from the contraction of the muscle and is removed by the kidneys. A disorder of the kidney and/or urinary tract will reduce the excretion of creatinine and thus raise blood serum levels. Creatinine is traditionally used with BUN to assess for impaired kidney function. Elevated levels can also indicate dysfunction in the prostate. 

This test measures the amount of creatinine in your blood and/or urine. Creatinine is a waste product produced in your muscles from the breakdown of a compound called creatine. Creatine is part of the cycle that produces energy needed to contract your muscles. Both creatine and creatinine are produced by the body at a relatively constant rate. Almost all creatinine is excreted by the kidneys, so blood levels are a good measure of how well your kidneys are working. The quantity produced depends on the sex, size or age of the person and their muscle mass. For this reason, creatinine concentrations will be slightly higher in men than in women and children

Carbon Dioxide is a measure of bicarbonate in the blood. CO2, as bicarbonate, is available for acid-base balancing. Bicarbonate neutralizes metabolic acids in the body. Elevated levels of CO2 are associated with metabolic alkalosis and hypochlorhydria. Decreased levels are associated with metabolic acidosis.  

The eGFR is a calculated estimate of the kidney’s Glomerular Filtration Rate. It uses 4 variables: age, race, creatinine levels and gender to estimate kidney function. Levels below 90 are an indication of a mild loss of kidney function. Levels below 60 indicate a moderate loss of kidney function and may require a visit to a renal specialist for further evaluation.

Metabolic Health

Uric acid is produced as an end-product of purine, nucleic acid,and nucleoprotein metabolism. Levels can increase due to over-production by the body or decreased excretion by the kidneys. Increased uric acid levels are associated with gout, atherosclerosis, oxidative stress, arthritis, kidney dysfunction, circulatory disorders and intestinal permeability. Decreased levels are associated with detoxification issues, molybdenum deficiency, B12/folate anemia, and copper deficiency.

Albumin is one of the major blood proteins. Produced primarily in the liver, Albumin plays a major role in water distribution and serves as a transport protein for hormones and various drugs. Albumin levels are affected by digestive dysfunction and a decreased albumin can be an indication of malnutrition, digestive dysfunction due to HCl need (hypochlorhydria), or liver dysfunction. Malnutrition leads to a decreased albumin level in the serum primarily from lack of available essential amino acids. Decreased albumin can also be a strong indicator of oxidative stress and excess free radical activity. Increased albumin is a strong indicator of dehydration. 

Total serum protein is composed of albumin and total globulin. Conditions that affect albumin and total globulin readings will impact the total protein value. A decreased total protein can be an indication of malnutrition, digestive dysfunction due to HCl need, or liver dysfunction. Malnutrition leads to a decreased total protein level in the serum primarily from lack of available essential amino acids. An increased total protein is most often due to dehydration. 

Total Globulin is composed of individual globulin fractions called alpha 1, alpha 2, beta, and gamma fractions. The total globulin level is greatly impacted by concomitant increases or decreases in one or more of these fractions. Globulins function to transport substances in the blood and constitute the antibody system, clotting proteins, and complement. Globulins are produced in the liver, the reticuloendothelial system, and other tissues.Care must be taken when making a diagnosis based upon the total globulin alone because total globulin is composed of 4 different fractions. Inflammatory, degenerative, or infectious processes are associated with increased production of antibodies.

The albumin/globulin ratio is the ratio between the albumin and total globulin levels. A decreased ratio is associated with liver dysfunction and immune activation from infectious or inflammatory processes. An increased Albumin/Globulin ratio is uncommon and is usually due to dehydration. 

Liver & Gallbladder Health

Alkaline phosphatase (ALP) is a group of isoenzymes that originate in the bone, liver, intestines, skin, and placenta. It has a maximal activity at a pH of 9.0-10.0, hence the term alkaline phosphatase. Decreased levels of ALP have been associated with zinc deficiency. Elevated levels of ALP in the serum can occur with any liver dysfunction, it is especially sensitive to any type of obstruction in the biliary tract, both intra and extra-hepatic, both severe and mild.

ALT is an enzyme present in high concentrations in the liver and to a lesser extent skeletal muscle, the heart, and kidney. ALT will be liberated into the bloodstream following cell damage or destruction. Any condition or situation that causes damage to the hepatocytes will cause leakage of ALT into the bloodstream.

AST is an enzyme present in highly metabolic tissues such as skeletal muscle, the liver, the heart, kidney and lungs. This enzyme is at times released into the bloodstream following cell damage or destruction. AST levels will be increased when liver cells and/or heart muscle cells and/or skeletal muscle cells are damaged. The cause of the damage must be investigated. Low levels are associated with a B6 deficiency.

Gamma Glutamyl Transferase (GGT) is an enzyme that is present in highest amounts in the liver cells and to a lesser extent the kidney, prostate,and pancreas. It is also found in the epithelial cells of the biliary tract. GGT will be liberated into the bloodstream following cell damage or destruction and/or biliary obstruction. GGT is induced by alcohol and can be elevated following chronic alcohol consumption and in alcoholism. Decreased levels are associated with vitamin B6 and magnesium deficiency.

The total bilirubin is composed of two forms of bilirubin: Indirect or unconjugated bilirubin, which circulates in the blood on its way to the liver and direct or conjugated bilirubin, which is the form of bilirubin made water-soluble before it is excreted in the bile. An increase in total bilirubin is associated with dysfunction or blockage in the liver, gallbladder, or biliary tree, or red blood cell hemolysis. A decrease in Total Bilirubin is associated with an increase in oxidative stress. 

Iron Health

Serum iron reflects iron that is bound to serum proteins such as transferrin. Serum iron levels will begin to fall somewhere between the depletion of the iron stores and the development of anemia. Increased iron levels are associated with liver dysfunction, conditions of iron overload (hemochromatosis and hemosiderosis), and infections. Decreased iron levels are associated with iron deficiency anemia, hypochlorhydria, and internal bleeding. The degree of iron deficiency is best appreciated with ferritin, TIBC, and % transferrin saturation levels. 

Ferritin is the main storage form of iron in the body. Decreased levels are strongly associated with iron deficiency where it is the most sensitive test to detect an iron deficiency. Increased levels are associated with iron overload, an increasing risk of cardiovascular disease, inflammation, and oxidative stress.

Total Iron Binding Capacity is an approximate estimation of the serum transferrin level. Transferrin is the protein that carries most of the iron in the blood. Elevated levels are associated with iron deficiency anemia. Decreased levels of TIBC are associated with possible iron overload or a protein deficiency.

Transferrin is produced in the liver and the main protein in the blood binding to iron transporting it throughout the body. Transferrin levels in the blood is used to assess both the iron status and also nutritional status and liver function. Elevated levels are associated with iron deficiency, whilst low levels may be associated with iron overload, inflammation & liver dysfunction. 

The % transferrin saturation  index is a calculated value that tells how much serum iron is bound to the iron-carrying protein transferrin. A % transferrin saturation value of 15% means that 15% of iron-binding sites of transferrin are being occupied by iron. It is a sensitive screening test for iron deficiency anemia if it is below the optimal range. It is a sign of iron overload or too much iron in the blood if it is above the optimal range.


Cholesterol is a steroid found in every cell of the body and in the plasma. It is an essential component in the structure of the cell membrane where it controls membrane fluidity. It provides the structural backbone for every steroid hormone in the body, which includes adrenal and sex hormones and vitamin D. The myelin sheaths of nerve fibres are derived from cholesterol and the bile salts that emulsify fats are composed of cholesterol. Cholesterol is made in the body by the liver and other organs and from dietary sources. 

Serum triglycerides are composed of fatty acid molecules that enter the bloodstream either from the liver or from the diet. Clients that are optimally metabolising their fats and carbohydrates tend to have a triglyceride level about one-half of the total cholesterol level. Levels will be elevated in metabolic syndrome, fatty liver, in clients with an increased risk of cardiovascular disease, hypothyroidism, and adrenal dysfunction. Levels will be decreased in liver dysfunction, a diet deficient in fat, and inflammatory processes.

LDL functions to transport cholesterol and other fatty acids from the liver to the peripheral tissues for uptake and metabolism by the cells. It is known as bad cholesterol  because it is thought that this process of bringing cholesterol from the liver to the peripheral tissue increases the risk for atherosclerosis. An increased LDL cholesterol is just one of many independent risk factors for cardiovascular disease. It is also associated with metabolic syndrome, oxidative stress, and fatty liver.

HDL functions to transport cholesterol from the peripheral tissues and vessel walls to the liver for processing and metabolism into bile salts. It is known as “good cholesterol” because it is thought that this process of bringing cholesterol from the peripheral tissue to the liver is protective against atherosclerosis. Decreased HDL is considered atherogenic, increased HDL is considered protective. 

Non-HDL cholesterol represents the circulating cholesterol that is not carried by HDL (the protective carrier that collects cholesterol from tissues and blood vessels and transports it back to the liver). An elevated Non-HDL Cholesterol is associated with an increase risk of cardiovascular disease and related events.

Thyroid Health

TSH or thyroid-stimulating hormone is a hormone produced by the anterior pituitary to control the thyroid gland’s production of T4, to store T4, and to release it into the bloodstream. TSH synthesis and secretion is regulated by the release of TRH (Thyroid Releasing Hormone) from the hypothalamus. TSH levels describe the body’s desire for more thyroid hormone (T4 or T3), which is done in relation to the body’s need for energy. A high TSH is the body’s way of saying “we need more thyroid hormone”. A low TSH reflects the body’s low need for thyroid hormone.

T-3 is the most active thyroid hormone and is primarily produced from the conversion of thyroxine (T-4) in the peripheral tissue. T-3 is 4 -5 times more metabolically active than T-4. Total T3 reflects the total amount of T3 present in the blood i.e. amount bound to protein and free levels.

T-4 is the major hormone secreted by the thyroid gland. T-4 production and secretion from the thyroid gland are stimulated by the pituitary hormone TSH. Deficiencies of zinc, copper, and vitamins A, B2, B3, B6 and C will cause a decrease in production of T4 by the follicles of the thyroid gland. Most of the T4 in the blood is in the bound form, i.e. bound to proteins in the blood such as thyroid binding globulin.

Free T-4 is the unbound form of T4 in the body. Only about 0.03 – 0.05% of circulating T4 is in the free form. Free T-4 will be elevated in hyperthyroidism and decreased in hypothyroidism.

T-3 is the most active thyroid hormone and is primarily produced from the conversion of thyroxine (T-4) in the peripheral tissue. Free T3 is the unbound form of T3 measured in the blood. Free T3 represents approximately 10% of circulating T3 in the blood. Free T-3 levels may be elevated with hyperthyroidism and decreased with hypothyroidism.

Measuring Free T3 (FT3) and Free T4 (FT4) helps assess how much free and active thyroid hormone is available for use. Calculating the ratio of FT3 to FT4 can provide further information about the current thyroid status.


High Sensitivity C-Reactive Protein (Hs-CRP) is a blood marker that can help indicate the level of chronic inflammation in the body. Increased levels are associated with an increased risk of inflammation, cardiovascular disease, stroke, and diabetes.

Vitamins & Minerals

This vitamin D test measures for levels of 25-OH vitamin D to assess vitamin D status. An increased serum vitamin D is usually seen with clients that are supplementing with too much vitamin D. A decreased serum vitamin D is extremely common and is a sign of vitamin D deficiency. Vitamin D deficiency has been associated with many disorders including many forms of cancer, hypertension, cardiovascular disease, chronic inflammation, chronic pain, diabetes along with mental health disorders.

Serum calcium levels, are primarily regulated by parathyroid hormone (PTH) and vitamin D. A low calcium level indicates that calcium regulation is out of balance and not necessarily that the body is deficient of calcium and needs supplementation. Other potential imbalances would need to be investigated – ie Vitamin D, hypochlorhydria, mineral need as a few examples before supplementing. 

Corrected calcium is a measure used to assess the amount of calcium circulating in your bloodstream, accounting for variations in albumin levels. Calcium plays a crucial role in various bodily functions, including bone health, muscle contraction, and nerve signaling. However, because calcium often binds to proteins in the blood, such as albumin, fluctuations in albumin levels can affect the accuracy of calcium measurements. Corrected calcium adjusts for these variations, providing a more accurate reflection of your body’s calcium status.

Phosphorous levels are regulated by parathyroid hormone (PTH). Plasma levels may be decreased after a high carbohydrate meal or in people with a diet high in refined carbohydrates. Serum phosphorous is a general marker for digestion. Decreased phosphorous levels are associated with hypochlorhydria

Magnesium is important for many different enzymatic reactions, including carbohydrate metabolism, protein synthesis, nucleic acid synthesis, and muscular contraction. Magnesium is also needed for energy production and is used by the body in the blood clotting mechanism. An increased serum magnesium is associated with kidney dysfunction and thyroid hypofunction. A decreased magnesium is a common finding with muscle cramps. 

The Calcium:Albumin ratio is determined from serum calcium and albumin levels. Elevated levels can be a sign of protein deficiency or protein loss. Decreased levels could indicate a calcium and/or vitamin D insufficiency. 

The Calcium:Phosphorus ratio is determined from the serum calcium and serum phosphorus levels. This ratio is maintained by the parathyroid glands and is also affected by various foods. Foods high in phosphorus and low in calcium tend to disrupt the balance and shift the body toward metabolic acidity, depleting calcium and other minerals and increasing inflammation.

Sodium is an important blood electrolyte and functions to maintain osmotic pressure, acid-base balance, aids in nerve impulse transmission, as well as renal, cardiac, and adrenal functions. Increased sodium is most often due to dehydration (sweating, diarrhea, vomiting, polyuria, etc.) or adrenal stress. Decreased sodium levels are associated with adrenal insufficiency and edema.

Potassium is one of the main electrolytes in the body. Due to the critical functions of potassium for human metabolism and physiology, it is essential for the body to maintain optimal serum levels even though a small concentration is found outside of the cell. Potassium levels should always be viewed in relation to the other electrolytes. Potassium concentration is greatly influenced by adrenal hormones. As such, potassium levels can be a marker for adrenal dysfunction.

The sodium and potassium levels are under the influence of aldosterone and cortisol, both hormones produced by the adrenal glands. Aldosterone causes the body to retain sodium by causing a decreased excretion of sodium from the kidney. Aldosterone has the opposite effect on potassium causing the body to excrete potassium by increasing the excretion of potassium from the kidney.  


DHEA is produced primarily from the adrenals and is the most abundant circulating steroid in the human body and influences more than 150 known anabolic (repair) functions throughout the body and brain. It is the precursor for the sex hormones: testosterone, progesterone, and estrogen. Decreased levels are associated with many common age-related conditions, including diseases of the nervous, cardiovascular, and immune systems such as metabolic syndrome, coronary artery disease, osteoporosis, mood disorders and sexual dysfunction. Ideally, DHEA levels should be maintained at the level of a healthy 30-year-old to maximise the anti-aging effects.

Testosterone is the primary sex hormone for men. The total testosterone test measures both the testosterone that is bound to serum proteins and the unbound form (free testosterone).

In men, total testosterone is useful for assessing gonadal, adrenal, and pituitary function. 

In women, total testosterone can help in the evaluation of polycystic ovarian syndrome, testosterone-producing tumors of the ovary, tumours of the adrenal cortices, and congenital adrenal hyperplasia. 


Testosterone is the primary sex hormone for men. The free testosterone test measures the testosterone that is unbound to serum proteins such as Sex Hormone Binding Globulin (SHBG) and albumin. Levels of testosterone diminish with age and obesity, especially abdominal obesity. 


(For Men) 

Sex Hormone Binding Globulin (SHBG) is a protein produced primarily in the liver and to some extent the testes and the brain. SHBG acts as a transport molecule for carrying estrogen and testosterone around the body and delivering them to receptors on the cells.

(For women) 

Sex Hormone Binding Globulin (SHBG) is a protein produced primarily in the liver and to some extent the testes, uterus, brain, and placenta. SHBG acts as a transport molecule for carrying estrogen and testosterone around the body and delivering them to receptors on the cells. 



Estradiol is a minor hormone in men. Estradiol is synthesised from testosterone and androstenedione in men and plays a role in male sex hormone physiology. Low levels of estradiol in men affect bone density and risk of fractures if too low. High levels of estradiol in men are associated with abdominal obesity, an increased risk of cardiovascular disease, insulin sensitivity, and blood sugar dysregulation.


Estradiol (E2) is the most commonly measured estrogens, the others being estrone (E1) and estriol (E3). The serum estradiol level is not specific to any phase of the menstrual cycle. It is a general assessment of estradiol. Low levels of estradiol can be a risk factor for osteoporosis and bone fracture. Estradiol may improve the quality of life in menopausal women. Increased levels of estradiol in women suggest an increased risk of breast or endometrial cancer. 

Immune Health

The total White Blood Cell (WBC) count measures the sum of all the WBCs in the peripheral blood. White Blood Cells fight infection, defend the body through a process called phagocytosis, and produce, transport, and distribute antibodies as part of the immune process. It is important to look at the WBC differential count (neutrophils, lymphocytes, etc.) to locate the source of an increased or decreased WBC count. Decreased total White Blood Cell Levels are associated with chronic bacterial or viral infections, immune insufficiency, and may be seen in people eating a raw food diet. Increased total White Blood Cell Levels are associated with acute bacterial or viral infections and may be seen in people who eat a diet of highly refined foods.

Neutrophils are the white blood cells used by the body to combat bacterial infections and are the most numerous and important white cell in the body’s reaction to inflammation. Neutrophils – % tells us the % distribution of neutrophils in the total white blood cell count. Levels will be raised in bacterial infections. Decreased levels are often seen in chronic viral infections. 


Lymphocytes are a type of white blood cell. An increase in Lymphocytes – is usually a sign of a viral infection but can also be a sign of increased toxicity in the body or inflammation. Decreased levels are often seen in a chronic viral infection when the body can use up a large number of lymphocytes and oxidative stress. A decreased Lymphocytes may also indicate the presence of a fatigued immune response, especially with a low Total WBC count. 


Monocytes are white blood cells that are the body’s second line of defense against infection. They are phagocytic cells that are capable of movement and remove dead cells, microorganisms, and particulate matter from circulating blood. Levels tend to rise at the recovery phase of an infection or with chronic infection. 


Eosinophils are a type of White Blood Cell, which are often increased in people that are suffering from intestinal parasites or food or environmental sensitivities/allergies.

Basophils are one of the circulating white blood cells. They constitute a small percentage of the total white blood cell count. Basophils play an important role in the inflammatory process by releasing important substances, such as heparin, to prevent clotting in the inflamed tissue.Basophils will often be increased with tissue inflammation and is often seen with cases of intestinal parasites.


Full Blood Count

The hematocrit (HCT) measures the percentage of the volume of red blood cells in a known volume of centrifuged blood. It is an integral part of the Complete Blood Count (CBC) or Hematology panel. Elevated levels of hematocrit are associated with dehydration. An increased hematocrit is also associated with but by no means diagnostic of asthma or emphysema. Due to the lack of optimum oxygenation of the blood, the body will increase the red blood cell count to increase the number of cells that can be oxygenated. The hematocrit will go up accordingly. Low levels of hematocrit are associated with anemia. The hematocrit should be evaluated with the other elements on a CBC/Hematology panel to determine the cause and type of anemia. 

Hemoglobin is the oxygen-carrying molecule in red blood cells. Low levels of hemoglobin are associated with anemia. Measuring hemoglobin is useful to determine the cause and type of anemia and for evaluating the efficacy of anemia treatment. Hemoglobin levels may be increased in cases of dehydration.

The Mean Corpuscular Hemoglobin (MCH) is a calculated value and is an expression of the average weight of hemoglobin per red blood cell. MCH, along with MCV can be helpful in determining the type of anemia present.


The Mean Corpuscular Hemoglobin Concentration (MCHC) measures the average concentration of hemoglobin in the red blood cells. It is a calculated value. It is elevated with B12/folate deficiency and hypochlorhydria. Decreased levels are associated with a vitamin C need, vitamin B6 and iron deficiencies, and a heavy metal body burden.  

The MCV is a measurement of the volume in cubic microns of an average single red blood cell. MCV indicates whether the red blood cell size appears normal (normocytic), small (microcytic), or large (macrocytic). An increase or decrease in MCV can help determine the type of anemia present. An increased MCV is associated with B12, folate, or vitamin C deficiency. A decreased MCV is associated with iron and B6 deficiency. 

Mean Platelet Volume is a calculated measurement of the relative size of platelets in the blood. The average size of platelets increases when the body is producing more platelets and as such, the MPV can help in making assessments of platelet production in the bone marrow or platelet destruction. Elevated levels of MPV are seen with platelet destruction. 

Platelets or thrombocytes are the smallest of the formed elements in the blood. Platelets are necessary for blood clotting, vascular integrity, and vasoconstriction. They form a platelet plug, which plugs up breaks in small vessels. Increased platelets may be seen with atherosclerosis. Decreased levels are associated with oxidative stress, heavy metal body burden and infections.

The RBC Count determines the total number of red blood cells or erythrocytes found in a cubic millimeter of blood. The red blood cell functions to carry oxygen from the lungs to the body tissues and to transfer carbon dioxide from the tissues to the lungs where it is expelled. Increased levels are associated with dehydration, stress, a need for vitamin C and respiratory distress such as asthma. Decreased levels are primarily associated with anemia.

The Red Cell Distribution Width (RDW) is essentially an indication of the degree of abnormal variation in the size of red blood cells (called anisocytosis). Although the RDW will increase with vitamin BI2 deficiency, folic acid, and iron anemia, it is increased most frequently with vitamin B12 deficiency anemia.

I knew Sonia from our gym days so was delighted when I googled nutritionist and her name popped up first. I was at the end if my tehter as Ive just kept gaining and gaining weight for no apparent reason. I eat healthy and trained 3 to 4 times a week. Before my first consultation with Sonia I had blood tests and when I first saw her I told her my symptoms and she immediately said to go gluten free and take my temperature every morning for 2 weeks. This showed Sonia what she wanted to see and soon after I had my Dr's diagnosis. I also suffer with acid reflux. Dr said take gaviscon for 2 weeks, if it helps ill prescribe you something... I stopped eating nightshade foods, Google it... Who knew?! I've not had gaviscon since. Once we knew the root of the problem Sonia immediately got to work on mounds and mounds, of research, dietary needs and habit breaking suggestions. I'd have a snack at 10 and 3 and breakfast, lunch ant tea... I didn't need it, it was a habit. Managed to break that in a week... I had 2 12 week cycles with Sonia and I feel a lot better and less sluggish. I'm on the right road and I know this is not an overnight fix but with Sonia guidance and knowledge I'll get there. As yet, I've not lost any weight but it will come. If I'd not reconnected with Sonia, I don't know what I'd be doing now... Sorry for the long post... I could go on and on... Thank you Sonia x

I’m just at the end of my 12 week support with Sonia. It has been life changing for me! I knew I couldn’t maintain my lifestyle, as I at my heaviest l had ever been, feeling unhealthy! Sonia took the time to listen to me, and guide me through, a achievable plan, taking one step at a time with small changes. Then lunch and dinner ideas. A guide on different types of food , healthy sugars/fats. I’m definitely enjoying my new diet. Loosing weight, and definitely feel healthier happy, more energy. Definitely worth giving it a go, to help you change your lifestyle and feel good. I’m signing up again for another 12 weeks. looking forward to hearing what Sonia has planned for me.

It was my husband who saw I was despairing about my weight, bloatedness, puffiness and who knew I was unhappy within myself… he knows Sonia and after much persuasion from him I decided to book my half hour session thinking it’ll be a waste of time … maybe I’ll try slimming world again (for the umpteenth time!). Well .. that half an hour with Sonia turned on a switch .. she listened to what my ailments were, how unhappy I was with myself and because of certain different medical reasons how I felt down about the way I was… she listened and said I can help you and I believed she could .. that half an hour gave me hope! 12 weeks down the line I’m at the end of the tunnel .. it’s bright.. I feel fantastic.. weight is coming off, I’m eating delicious food and discovering me again, I feel healthier , no more sluggish feeling in the afternoons, I don’t want to have a nap! It isn’t a quick fix, it’s slow , steady and understanding the different food types and how they help and it’s patience. I can’t praise Sonia enough, I no longer feel guilty about what I eat as it’s just delicious, I have loved cooking new recipes and have a few favourites. Sonia … a big THANK YOU!

Working with Sonia, my Personalised Nutritional Therapist, taught me so much about my health and diet. Having Rheumatoid Arthritis and not knowing what the triggers were, I was eating food that I enjoyed but was not good for the condition. Sonia got to work by checking my family history, working with my doctor and checking my Blood test for any contra indications, looking at my daily food intake and recomending Food and fruits that was good for me and additionl food supplements that contributes to the maintenance of the whole body. I'm on a gluten free diet, my overall health has improved and I am happy that I found Sonia, and I would recommend her to anyone looking to improve their health.
With Sonia's help i lost 14 kg and never felt better like now. i am completely different person my mood improved and i am full of energy. besides that i learned about nutritional needs and how much important it is for a healty lifestyle and much more. i definitely recommend Sonya she is the best.

I came to Sonia with a few health concerns. She has helped me find supplements to support this and most of the symptoms have gone! I have learnt so much with how my body reacts to certain foods,so I can now move forward and avoid these for the future.

Sonia is a wealth of information for all your nutritional needs. Approachable & genuinely wants to help. Her passion for what she does is very evident. I followed her 14 day detox programme. This plan was so easy to follow with clear & delicious recipes as well as explanations on what incorporates a balanced diet. Sonia regularly checked in and I felt totally supported. My diet had become shocking living off fast carbs and not caring what I was fuelling my body with. I was always tired. After 14 days I lost 7lb & 5 inches but the most remarkable change was how I felt in myself. Stronger, fitter & healthier. Sleep improved & my mood. My energy levels have rocketed. I have made eating a balanced diet part of my everyday norm and haven’t looked back. I’m seeing results both in my training and general everyday life. What you fuel your body with really makes a dramatic difference. I 100% recommend Sonia. She is exactly what you need to meet all your nutritional needs.
