Essential information about your test

What's in the test:

What we measure:

  • Haemoglobin - Haemoglobin is the oxygen-carrying protein that gives red blood cells – and your blood – its rich red colour. This test checks how much haemoglobin is in your blood, giving a clear picture of how well oxygen is being transported throughout your body. It’s a key indicator of how efficiently your body is functioning.
  • Haematocrit (HCT) - measures the volume of your blood that’s made up of red blood cells.
  • Red blood cell (RBC) - This test measures the concentration of red blood cells (RBCs) in your bloodstream, which are essential for transporting oxygen from the lungs to tissues throughout the body and removing carbon dioxide for exhalation. An optimal RBC count is critical for supporting cellular energy, physical performance, and overall metabolic function.
  • MCV - Mean Corpuscular Volume indicates the average size of your red blood cells. This measurement provides insight into how effectively your red blood cells may be transporting oxygen throughout the body
  • MCH - Mean Corpuscular Haemoglobin reflects the average mass of haemoglobin within individual red blood cells
  • MCHC - Mean Corpuscular Haemoglobin Concentration represents the average concentration of haemoglobin within red blood cells.
  • Platelets - Platelets are small, disc-shaped cell fragments produced in the bone marrow that play a key role in preventing blood loss. When a blood vessel is damaged, platelets rapidly activate, gather at the site, and help form a stable clot to seal the injury. This clotting process is essential for wound healing and maintaining vascular integrity.
  • MPV - Mean Platelet Volume reflects the average size of platelets circulating in the blood. As an indicator of platelet activity, MPV can offer insights into how actively the bone marrow is producing platelets.
  • WCC - White Cell Count indicates the total number of white blood cells in your bloodstream. These cells are essential components of the immune system, working to detect, attack, and eliminate harmful pathogens such as bacteria, viruses, and other foreign substances. White cells also play a role in immune memory, helping your body respond more efficiently to repeated exposures.
  • Lymphocytes count - Lymphocytes are specialised white blood cells that play a central role in the body’s adaptive immune response. They help recognise, target, and eliminate specific bacteria, viruses, and other pathogens. This group includes T cells, B cells, and natural killer (NK) cells, each with distinct immune functions. Lymphocytes also produce antibodies and memory cells, allowing the immune system to respond more rapidly to future exposures. An elevated or reduced lymphocyte count may indicate infection, immune system activity, or underlying haematological conditions
  • Basophil Count - Basophils are the least common type of white blood cell, but they play an important role in allergic reactions and inflammation. They release histamine and other chemicals that help the body respond to allergens, infections, and injury. Elevated basophils may be linked to allergic conditions, chronic inflammation, or certain blood disorders.
  • Lymphocyte Count Lymphocytes are crucial defenders in your immune system, responsible for recognizing and fighting viruses, bacteria, and even abnormal or cancerous cells. They include B cells (which produce antibodies) and T cells (which directly attack infected cells or coordinate immune responses). Changes in lymphocyte levels may indicate infection, immune dysfunction, or blood-related conditions.
  • Eosinophil Count - Eosinophils help combat parasitic infections and are strongly involved in allergic reactions and asthma. They release enzymes and chemicals that regulate inflammation. Elevated eosinophils may be a sign of allergies, asthma, parasitic infections, or certain autoimmune conditions.
  • Monocyte Count - Monocytes are large white blood cells that circulate in the bloodstream before moving into tissues, where they become macrophages. Macrophages “eat” and break down bacteria, dead cells, and debris, making them vital for both defence and tissue repair. High monocyte levels may be seen in infections, inflammation, or immune-related disorders.
  • Neutrophil Count - Neutrophils are the most abundant type of white blood cell and your body’s first line of defence against bacterial infections. They respond rapidly to infection or injury, engulfing and destroying harmful microbes. A low count may increase the risk of infections, while a high count often signals an active infection or inflammation.
  • Creatinine - Creatinine is a waste product made by your muscles and filtered out of the blood by the kidneys. Measuring creatinine levels helps assess how well your kidneys are working, as a rise may signal reduced kidney function.
  • eGFR (Estimated Glomerular Filtration Rate) - eGFR is a calculation based on creatinine, age, sex, and other factors. It estimates how efficiently your kidneys are filtering waste from the blood, giving a clear picture of overall kidney function. Lower eGFR values may indicate early or advanced kidney disease.
  • Urea - Urea is another waste product created when your body breaks down protein. Healthy kidneys remove urea through urine. Elevated levels can suggest dehydration, high protein intake, or reduced kidney function.
  • Cystatin C - Cystatin C is a protein produced by all cells in the body and cleared by the kidneys. Unlike creatinine, it is less influenced by muscle mass, making it a sensitive and reliable marker of kidney health.
  • Sodium - Sodium is an essential electrolyte that helps control fluid balance, blood pressure, and nerve and muscle function. Abnormal levels may point to dehydration, kidney issues, or hormonal imbalances.
  • Potassium - Potassium is vital for heart rhythm, muscle contractions, and nerve signals. Both high and low potassium levels can be serious, sometimes causing muscle weakness, irregular heartbeat, or other complications.
  • Chloride - Chloride works with sodium and potassium to maintain fluid balance, acid–base balance, and proper nerve and muscle function. Changes in chloride can reflect dehydration, kidney disorders, or problems with acid–base regulation.
  • Phosphate - Phosphate supports energy production, bone strength, and cell function. It is tightly regulated by the kidneys, vitamin D, and hormones. Abnormal phosphate levels may be linked to bone disease, kidney problems, or hormonal changes.
  • Magnesium - Magnesium is needed for hundreds of biochemical reactions, including energy production, muscle function, and nerve transmission. Low or high levels may cause fatigue, cramps, irregular heartbeat, or neurological symptoms.
  • Calcium (Adjusted) - Calcium is essential for healthy bones, teeth, nerves, and muscles. “Adjusted calcium” accounts for protein levels in the blood (mainly albumin), giving a more accurate measure of the calcium available to the body. Abnormal levels can signal bone disease, vitamin D problems, or parathyroid hormone imbalances.
  • Albumin - Albumin is the main protein in your blood, produced by the liver. It helps maintain fluid balance, transport hormones, vitamins, and medicines, and supports overall health. Low levels may suggest liver disease, kidney problems, malnutrition, or inflammation.
  • Alkaline Phosphatase - Alkaline Phosphatase is an enzyme found in the liver, bones, and other tissues. Measuring ALP helps assess liver and bone health. Raised levels may indicate liver disease, blocked bile ducts, or increased bone turnover (such as in growth, healing, or certain bone conditions).
  • Iron - Iron is an essential mineral that your body uses to make haemoglobin — the protein in red blood cells that carries oxygen around the body. Low iron can cause anaemia and fatigue, while high levels may indicate overload conditions.
  • Ferritin - Ferritin is a protein that stores iron in your body. Measuring ferritin shows how much iron you have in reserve. Low levels suggest iron deficiency, while high levels may indicate inflammation or iron overload.
  • Transferrin - Transferrin is a protein that carries iron through the blood to where it’s needed. Measuring transferrin helps assess how well your body is transporting and regulating iron.
  • Transferrin Saturation - These measures how much of the transferrin in your blood is loaded with iron. It provides insight into whether your body has enough available iron for healthy red blood cell production.
  • Total Iron Binding Capacity (TIBC) - TIBC reflects the total amount of iron that your blood proteins (mainly transferrin) can carry. It is often higher when iron stores are low, making it useful for diagnosing iron deficiency.
  • Vitamin D - Vitamin D is vital for healthy bones, muscles, and immune function. It helps your body absorb calcium and phosphate. Low levels are common, especially in winter, and can cause fatigue, weak bones, low mood, or increased risk of infections.
  • Folic Acid (Vitamin B9) - Folic acid is a B vitamin needed to make red blood cells and DNA. It plays a key role in energy production and cell growth. Low levels may cause anaemia, fatigue, or, in pregnancy, increase the risk of developmental problems.
  • Vitamin B12 - Vitamin B12 is essential for healthy nerves, red blood cell production, and energy metabolism. Deficiency can lead to tiredness, numbness, tingling, memory issues, or anaemia. It is more common in people with restricted diets (such as vegan), gut absorption issues, or autoimmune conditions.
  • Thyroid Stimulating Hormone (TSH) - TSH is made by the pituitary gland and controls how much hormone your thyroid produces. High levels usually suggest an underactive thyroid (hypothyroidism), while low levels may point to an overactive thyroid (hyperthyroidism).
  • Free Thyroxine (fT4) - Free T4 is the main hormone released by the thyroid gland. It helps regulate metabolism, energy, and body temperature. Measuring fT4 alongside TSH shows whether your thyroid is working normally or if it’s under- or overactive.
  • Free Triiodothyronine (fT3) - Free T3 is the active thyroid hormone that drives many of the body’s metabolic processes. It is especially useful in assessing suspected overactive thyroid, as it can be raised even when fT4 appears normal.
  • Anti-Thyroglobulin Antibodies (Anti-Tg) - These antibodies target thyroglobulin, a protein made by the thyroid gland. Their presence may indicate autoimmune thyroid conditions such as Hashimoto’s thyroiditis or, less commonly, Graves’ disease.
  • Anti-Thyroid Peroxidase (TPO) Antibodies - TPO antibodies attack thyroid peroxidase, an enzyme essential for thyroid hormone production. High levels are commonly seen in autoimmune thyroid disease, particularly Hashimoto’s and Graves’ disease, and can help explain long-term thyroid dysfunction.
  • Glucose (Random) - Glucose is the main type of sugar in your blood and your body’s primary energy source. Measuring glucose gives a snapshot of your current blood sugar level, which can help detect diabetes or prediabetes.
  • HbA1c (3-month blood sugar control) - HbA1c reflects your average blood sugar levels over the past 2–3 months. Unlike a single glucose reading, it shows long-term blood sugar control and is a reliable marker for diagnosing and monitoring diabetes.
  • Insulin - Insulin is the hormone that helps move glucose from the bloodstream into your cells for energy. Measuring insulin levels can show how well your body is handling sugar and whether insulin resistance (a key feature of type 2 diabetes) may be present.
  • C-Peptide - C-Peptide is released in equal amounts to insulin when your body makes its own insulin. Measuring it helps distinguish between type 1 and type 2 diabetes and shows whether your pancreas is still producing insulin effectively.
  • C-Reactive Protein (CRP) - CRP is a protein made by the liver in response to inflammation. Levels rise when there is infection, injury, or chronic inflammatory activity in the body. Measuring CRP helps detect hidden inflammation and can support the investigation of conditions such as infections, autoimmune disease, or cardiovascular risk.
