A measurement of the volume of red blood cells compared to the total blood volume (red blood cells and plasma).

A measurement of the average amount of haemoglobin in a single red blood cell.

A measurement of haemoglobin concentration in a red blood cell relative to the cells volume.

A measurement of the mean size of red blood cells.

A component of blood that carries oxygen and carbon dioxide around the body.

A component of blood that prevent bleeding and allow blood to clot.

A mineral the body needs to make haemoglobin, a substance in the blood that carries oxygen from the lungs to the body.

A protein that binds to iron and stores it for use by the body.

A Total Iron Binding Capacity (TIBC) blood test measures how well your blood can carry iron. It assesses the amount of transferrin, a protein in your blood that binds to and transports iron throughout your body. 

A protein that transports iron through the blood to various tissues, such as the liver, spleen, and bone marrow.

A blood glucose test is used to find out if your blood sugar levels are in a healthy range. It can be used to help diagnose and monitor diabetes.

An HbA1c blood test, also known as a glycated hemoglobin test, is a blood test that measures your average blood sugar levels over the past 2-3 months. 

Insulin is a hormone that your pancreas makes. It helps move blood glucose (blood sugar) from your bloodstream into your cells where it’s used for energy. Testing measures the amount of insulin, the hormone that lets cells take in glucose.

A Total Antioxidant Status (TAS) blood test measures the overall antioxidant capacity of a blood sample, reflecting the body’s ability to neutralize harmful free radicals (known to cause cellular damage).

Albumin is a protein found in the plasma of blood, albumin carries substances such as hormones, medicines, and assists with neutralisation of free radicals.

A way of measuring the calcium in our blood more accurately by taking your albumin level into account of how much usable calcium is in your blood.

A mineral in the body that is needed hundreds of processes to keep the body healthy.

Measures the amount of folate (vitamin B9) in your blood. This test is used to assess your folate levels, which are crucial for various bodily functions like red blood cell formation, DNA synthesis, and cellular repair.

A vitamin B12 blood test measures the total amount of vitamin B12 in your blood. It’s used to diagnose and monitor vitamin B12 deficiency.

A 25-hydroxyvitamin D (25(OH)D) blood test, also known as a vitamin D test, measures the level of vitamin D in your blood. This test is the most accurate way to determine your overall vitamin D status. 

A zinc blood test measures the amount of zinc in your blood. Zinc is an essential mineral that plays a vital role in many bodily functions, including immune system support, wound healing, and cell growth. 

A total cholesterol blood test measures the overall amount of cholesterol in your blood, including both HDL and LDL cholesterol. 

Commonly known as ‘good’ cholesterol, HDL carries LDL (bad) cholesterol away from the arteries and back to the liver.

A type of fat that is the most common type of fat in the blood, used by the body for energy.

Commonly known as ‘bad’ cholesterol, LDL is a fat that circulates in the blood, moving cholesterol around the blood stream.

A Helicobacter pylori (H. pylori) blood test detects the presence of antibodies in the blood, indicating past or present infection with this bacteria. 

The test analyses a stool sample for the presence of Helicobacter pylori (H. pylori) antigens, which are substances that trigger the body’s immune response to the bacteria. 

An anti-tissue transglutaminase (tTG) blood test is a key part of diagnosing coeliac disease. It measures the levels of tTG antibodies in the blood, which are produced when the body reacts to gluten in people with coeliac disease.
