Age restriction on blood tests

We're unable to offer blood tests for those under the age of 18 unless it is part of a routine GP appointment and the clinician believes it suitable.

What biomarkers are tested?

• Vitamin B12 - This biomarker measures vitamin B12, essential for red blood cell production and nerve function. Low levels of vitamin B12 can cause anaemia and contribute to fatigue.
• Vitamin D: A vital fat-soluble vitamin that supports bone, muscle, and immune system health. Our bodies can produce most of the Vitamin D they need through exposure to sunlight. Still, we can also obtain it from specific foods and supplements.
• Iron - This biomarker measures the level of iron, which is necessary for the production of haemoglobin. Low levels of iron can cause anaemia and contribute to fatigue.
• Ferritin: A biomarker reflecting iron levels in the body. The test measures ferritin levels to diagnose iron deficiency or excess, monitor treatment, and evaluate conditions like anaemia and liver disease.
• Albumin: A protein the liver produces that helps transport substances in the blood. Low levels can indicate liver damage or disease.
• Calcium: Essential mineral for bone health and bodily functions. Calcium test measures blood levels to assess bone health and nerve/muscle function and detect disorders.
• Magnesium: An essential mineral involved in various physiological processes. Magnesium test measures its levels in the blood, aiding in diagnosing magnesium deficiencies or imbalances.
• Zinc: Essential mineral involved in various physiological processes. The zinc test measures its levels in the body—a biomarker for nutritional status, immune function, and overall health assessment.
• Total Iron-Binding Capacity (TIBC): Measures the blood's ability to bind iron. The test helps diagnose and monitor conditions related to iron metabolism and anaemia. TIBC reflects the body's iron-carrying capacity, aiding in evaluating iron deficiency or overload.
• Transferrin: A protein that transports iron in the blood. Transferrin test measures its levels to assess iron status and diagnose conditions like anaemia. It helps evaluate iron deficiency and monitor response to treatment.
• Transferrin saturation (TSAT): Measures the amount of iron bound to transferrin in the blood. This test assesses iron metabolism and helps diagnose iron deficiency or overload. TSAT provides insights into iron status and guides treatment decisions.
