This may involve nutrition programming or therapeutic nutrition - check out our blog for more information.

What we test

Blood Glucose

Blood glucose is generated from carbohydrates and to use this fuel for energy your body needs insulin. With type 2 diabetes the cells either ignore the insulin or the body doesn't produce enough of it. Glucose then builds up leading to problems with the heart, kidneys, eyes, nerves, and blood vessels.

This blood test measures:

If you have diabetes your body doesn't process glucose effectively.

Liver Function (LFTs)

Your liver processes drugs and alcohol, filters toxic chemicals, stores vitamins and minerals, and makes bile, proteins and enzymes. This liver function test examines enzymes and other markers for evidence of damage to your liver cells or a blockage near your liver which can impair its function.

This liver function test measures:

Bilirubin tests are use to screen for or to detect and monitor liver disorders or haemolytic anaemia.

Alkaline phosphatase (ALP) is an enzyme located mainly in the liver and the bones. High levels can indicate liver disease.

Aspartate aminotransferase (AST) is an enzyme created mainly by the liver and the heart. High levels can indicate damage to your liver caused by alcohol, drugs or hepatitis.

Alanine aminotransferase (ALT) is an enzyme mainly produced by the liver. A good indicator of liver damage caused by alcohol, drugs or hepatitis.

Gamma-glutamyl transferase (GGT) is a liver enzyme which can be used to diagnose alcohol abuse as it is typically raised in long term drinkers.

Albumin is a protein which keeps fluid from leaking out of blood vessels, nourishes tissues, and carries hormones, vitamins, drugs, and ions like calcium throughout the body. Albumin is made in the liver and is sensitive to liver damage.

A measure of all of the proteins in the plasma portion of your blood. Proteins are important building blocks of all cells and tissues - they are important for body growth and health.

Kidney Function

Your kidneys filter waste from your body and regulate salts in your blood. They also produce hormones and vitamins that direct cell activities in many organs and help to control blood pressure. When the kidneys aren't working properly, waste products and fluid can build up to dangerous levels creating a life-threatening situation.

This kidney function test measures:

Helps regulate the water and electrolyte balance of your body, and is important in the function of your nerves and muscles. Too much sodium can indicate kidney disease.

Minor changes in serum potassium ca have significant consequences. An abnormal concentration can alter the function of the nerves and muscles for example, the heart muscle may lose its ability to contract.

Chloride, like sodium, helps to maintain the balance of fluid in the body. Raised levels can be caused by eating too much salt, dehydration, diarrhoea, certain medications and also kidney disease.

Higher than normal levels suggests trouble maintaining pH balance either by failing to remove carbon dioxide or because of an electrolyte imbalance. Elevations may be seen with severe vomiting, chronic lung problems and some hormonal disorders. Low levels may be seen with chronic diarrhoea, diabetic ketoacidosis and kidney failure.

A high concentration of this waste product can indicate dehydration or that your kidneys aren’t working properly.

A waste molecule generated from muscle metabolism, and an accurate marker of kidney function.

The estimated glomerular filtration rate (eGFR) measures how well your kidneys filter the wastes from your blood and is the best overall measure of kidney function.

Full blood count with differential

The full blood count is used as a broad screening test to check for such disorders as anaemia (decrease in red blood cells or haemoglobin), infection, and many other diseases. It is actually a group of tests that examine different parts of the blood. Results from the following tests provide the broadest picture of your health.

The full blood count measures

Responsible for carrying oxygen around the body. A high count can increase the risk of heart attack or stroke, whilst a low count can mean your body isn’t getting the oxygen it needs.

A good measure of your blood's ability to carry oxygen throughout your body. Elevated haemoglobin can be an indicator of lung disease, whilst a low result indicates anaemia.

A measure of the percentage of red blood cells in the total blood volume. Elevated haematocrit can increase the risk of heart attack or stroke.

Mean corpuscular volume (MCV) is a measure of the average size of the RBCs. The MCV is elevated when RBCs are larger than normal, eg in anaemia caused by vitamin B12 deficiency. When MCV is decreased, RBCs are smaller than normal as seen in iron deficiency anaemia.

Mean corpuscular haemoglobin (MCH) is a calculation of the average amount of oxygen-carrying haemoglobin inside a red blood cell. Large RBCs are large tend to have a higher MCH, while small red cells would have a lower value.

Mean corpuscular haemoglobin concentration (MCHC) is a calculation of the average concentration of haemoglobin inside a red cell. Decreased MCHC is seen in iron deficiency anaemia and thalassaemia.

Red cell distribution width (RDW) is a calculation of the variation in the size of your RBCs. In some anaemias, such as pernicious anaemia (due to vitamin B12 deficiency), the amount of variation in RBC size causes an increase in the RDW.

Responsible for fighting infection. A high count can indicate recent infection and even stress, whilst a low count can result from vitamin deficiencies, liver disease and immune diseases.

Basophils are a type of white blood cell. Basophils can increase in cases of leukaemia, long-standing inflammation and hypersensitivity to food.

A type of white blood cell. Can increase in response to allergic disorders, inflammation of the skin and parasitic infections. They can also occur in response to some infections or to various bone marrow malignancies.

A type of white blood cell. Can increase in response to infection as well as inflammatory disorders, and occasionally with some types of leukaemias. Decreased monocyte levels can indicate bone marrow injury or failure and some forms of leukaemia.

A type of white blood cell. Can increase with bacterial or viral infection, leukaemia, lymphoma, radiation therapy or acute illness. Decreased lymphocyte levels are common in later life but can also indicate steroid medication, stress, lupus and HIV infection.

A type of white blood cell. Can increase in response to bacterial infection, inflammatory disease, steroid medication, or more rarely leukaemia. Decreased neutrophil levels may be the result of severe infection or other conditions.

Responsible for blood clotting and healing. A high count can indicate a risk of thrombosis, whilst a low count can lead to easy bruising.

Vitamin D

Vitamin D is essential for bone strength as it helps the intestines absorb calcium. Calcium and vitamin D play a critical role in developing and maintaining your overall bone health, and when you don’t get enough you increase your risk of developing osteoporosis and the incidence of stress fractures.

This vitamin D test measures:

Although called a vitamin, vitamin D (25-OHD) is actually a steroid hormone which is activated by sunshine on the skin. It is essential for bone strength as it helps the intestines absorb calcium.

Active Vitamin B12

Vitamin B12 is an essential vitamin found in meat products and certain algae such as seaweed. It helps maintain healthy nerve cells and red blood cells and is also needed to make DNA, the genetic material in all cells. Both high and low vitamin B12 blood test levels may indicate an underlying problem. Low levels can suggest anaemia, a parasite or hyperthyroidism, whilst high levels can be a sign of liver disease, diabetes or kidney failure.

This vitamin B12 blood test measures:

Holotranscobalamin represents only 10-30% of the Vitamin B12 circulating in the blood but is the ONLY form of Vitamin B12 that is taken up and used by cells of the body, hence it’s other name - ACTIVE Vitamin B12.

Iron Studies

This simple iron test measures how much iron you have in your blood, as well as the amount of iron you have stored in your body. This iron test can be used to diagnose anaemia or monitor an existing iron deficiency. This iron test can also be used to investigate iron overload syndrome (haemochromatosis) which is an inherited condition where your body cannot remove excess iron.

This iron test measures:

An essential trace element is necessary for forming healthy red blood cells and for some enzymes.

A protein that binds iron and transports it around the body (also known as TIBC). High levels indicate iron deficiency.

Low levels typically indicate iron deficiency, and high levels can indicate iron overload.

The ferritin concentration within the blood stream reflects the amount of iron stored in your body and is reduced in anaemia.

Leptin
This blood test measures:

Leptin is a mediator of long-term regulation of energy balance, suppressing food intake and thereby inducing weight loss. Because leptin reduces food intake and body weight, the coexistence of elevated leptin levels with obesity is widely interpreted as evidence of “leptin resistance.”

Red blood cell Zinc & Magnesium
This blood test measures:

Red blood cell testing provides a measurement equivocal to intracellular levels, and is therefore more insightful than a regular zinc blood test.

Red blood cell testing provides a measurement equivocal to intracellular levels, and is therefore more insightful than a regular serum blood test.

Urine Iodine (random)

Iodine is an essential cofactors for proper thyroid function.

This random urine iodine test measures

Iodine is an essential trace element and an integral component of thyroid hormones. Thyroid hormones are required for normal growth and development of tissues and maturation of our bodies. Approximately 80% of iodine is excreted in the urine, making it a good marker of the previous day's intake.

Studies have shown that the iodine/ creatinine ratio from spot urine may serve as a useful and reliable alternative to 24-h urine collection.

High sensitivity CRP (hsCRP)

The hsCRP test is a highly sensitive quantification of CRP, a protein released into the blood by the liver during inflammation, and has been associated with the presence of heart disease.

This blood test measures:

A high-sensitivity C-reactive protein (hs-CRP) test measures low levels of CRP and may be used to help evaluate an individual for risk of cardiovascular disease
