✔️ Red blood cells

✔️ Mean corpuscular volume (MCV)

✔️ Mean corpuscular hemoglobin (MCH)

✔️ Mean corpuscular hemoglobin concentration (MCHC)

✔️ Red cell distribution width (RDW)

✔️ Mean platelet volume (MPV)

✔️ Platelets

✔️ White Blood Cell Count

Did you know?

1 in every 100,000 is born with the immune system disease called severe combined immunodeficiency (SCID), or 'bubble boy disease' — this means their body is unable to fight off infections.

Essential Vitamins

Vitamins play a key role in a healthy nervous system, energy levels, immune system and general wellbeing. A lack of vitamins can lead to affected mood, sleep disturbance, fitness and general aches and pain. Our test will cover the key vitamins that are necessary for your overall health.

Vitamin D

Vitamin D is a fat-soluble vitamin that primarily aids calcium absorption, promoting growth and mineralisation of your bones. Vitamin D does not really behave like a vitamin, rather it functions more like a hormone. It helps maintain strong and healthy bones by regulating calcium and phosphorus. It is also involved in different functions of your immune system, digestive, circulatory, nervous systems, whilst also affecting ageing.

Vitamin B12 & Active B12

Vitamin B12 is an essential vitamin that your body cannot produce. It is found in animal products and also added to some foods. Vitamin B12 has many important functions in your body. It is required for the production of red blood cells, DNA synthesis, and tissue repair. Because Vitamin B12 is commonly found in animal products, individuals following a vegetarian or vegan diet may require supplementation. An active B12 test measures the amount of B12 that available for your body to use.

Vitamin B9 (folate)

Folate, or folic acid, is a type of B vitamin. It helps to make DNA, repair DNA, and produce red blood cells. If you do not have enough folate in your diet, you may end up with a folate deficiency. This can occur in just a few weeks. Deficiencies may also occur if you have a disease or genetic mutation that prevents your body from absorbing or converting folate to its usable form. Folate deficiency can cause anaemia.


Inflammation refers to your body's process of fighting against things that harm it, such as infections, injuries, and toxins, in an attempt to heal itself. When something damages your cells, your body releases chemicals that trigger a response from your immune system. This test will help you find out how your body is dealing with inflammation.

High sensitivity C-reactive protein (hs-CRP)

C-reactive protein (CRP) is a protein produced by the liver in response to inflammation. A high level of CRP in the blood is a marker of inflammation that can be caused by a wide variety of conditions, from infections to chronic conditions. For women taking birth control pills, CRP may be elevated. A hs-CRP test is more sensitive than a standard test and can also be used to evaluate your risk of developing coronary artery disease (narrowing of your arteries).
Biomarker Tested: High sensitivity C-reactive protein

Full blood count

A weak or compromised immune system can be dangerous, and there could be different reasons why you might find yourself getting ill or having to go to the GP more often. This test will provide you wirh an extensive reading of how well your immune system is coping and what needs to be done to keep it strong.

Red blood cells

Red blood cells, also referred to as erythrocytes, are the most common type of blood cells. Red blood cells contain a protein called haemoglobin, which carries oxygen from the lungs to all parts of the body.

Mean corpuscular volume (MCV)

MCV is the average size of red blood cells. A smaller size may be a sign of iron deficiency, while larger sizes indicate vitamin B12 or folate deficiencies.

Mean corpuscular haemoglobin (MCH)

MCH is the average amount of haemoglobin in a single red blood cell. A low number may be a sign of iron deficiency, while a high number indicates vitamin B12 or folate deficiency.

Mean corpuscular haemoglobin concentration (MCHC)

MCHC refers to the average concentration of haemoglobin in red blood cells. A low number may be a sign of iron deficiency, while a high number often indicates sickle cell disease or hereditary spherocytosis.

Red cell distribution width (RDW)

RDW is a measurement of the variation of red blood cell sizes. A low number typically is not a cause of concern. A high number often indicates iron deficiency, vitamin B12 or folate deficiency, or a recent blood loss.

Mean platelet volume (MPV)

Mean platelet volume is the average size of platelets. Newer platelets tend to be larger than older ones. A low number may indicate aplastic anemia or thrombocytopenia. A high number is often an indication of certain inherited disorders.


Platelets help stop bleeding by promoting blood clotting. A low platelet count may indicate conditions such as bone marrow failure, viral infections, lupus, pernicious anemia (due to vitamin B12 deficiency), or affects of certain medications. A high platelet count may indicate leukaemia, inflammatory conditions, or myeloproliferative disorders (a disease that causes an abnormal growth of blood cells in the bone marrow).

White Blood Cell Count

White blood cells (WBCs) help the body fight off infections from bacteria, viruses, and fungi. There are different types of WBCs, each with its own function. These include:

Neutrophils - act as your body's first line of defence to fight off infections

Lymphocytes - help produce antibodies, which recognise and fight foreign invaders. They include B-cells, T-cells, and natural killer cells

Monocytes - move out of the circulating blood into tissues where they mature into macrophages (cells that destroy bacteria and other harmful organisms)

Eosinophils - help fight against parasites, cancer cells, and allergens. A low number is not a concern, while a high number may be a sign of parasitic infections

Basophils - stimulate the release of chemicals to aid in the body’s immune response. A low number is not a concern, while a high number may be a sign of an active allergic reaction

Frequently Asked Questions

Why should I take an immunity test?

Having a strong immune system ensures you are energetic and fit in your day-to-day life — naturally, you may experience being unwell during seasons where you are more likely to get the flu or catch a common cold, however your body should be able to bounce back quickly from these moments effortlessly. Knowing whether you have a strong immune system means you can find out either how you can keep it strong, or how you can boost it.
If left unchecked, your immune system might worsen and this could affect your wellbeing and lifestyle — your body could develop allergies when the body's immune system reacts to a particular substance as though it's harmful) or be more susceptible to more life-threatening conditions such as HIV, and autoimmune diseases.
