The most fundamental blood test in medicine — a complete enumeration of your red blood cells, white blood cells, and platelets across 12 markers. Reveals anaemia, infection, immune status, clotting capacity, and blood cell abnormalities. Commonly used as a baseline health screen, pre-operative check, and the starting point for investigating fatigue, recurrent infections, or unexplained bruising. No fasting required.

The Full Blood Count is the foundation upon which all other blood testing builds. It examines three cell populations in precise detail. Red blood cell indices (haemoglobin, haematocrit, MCV, MCH, MCHC, RDW) reveal your blood's oxygen-carrying capacity and the size, shape, and consistency of your red cells. Low haemoglobin indicates anaemia — the most common blood disorder globally — while MCV (mean cell volume) distinguishes between iron deficiency (small cells), B12/folate deficiency (large cells), and chronic disease anaemia. White blood cell differential (total WBC, neutrophils, lymphocytes, monocytes, eosinophils, basophils) maps your immune system's current state. Elevated neutrophils suggest bacterial infection; raised lymphocytes indicate viral infection; elevated eosinophils point to allergy or parasitic infection. Abnormal patterns can also flag more serious conditions including autoimmune disorders and blood cancers. Platelet count and MPV (mean platelet volume) assess your clotting system — low platelets increase bleeding risk, while elevated counts can indicate inflammation, iron deficiency, or myeloproliferative disorders. This is ClearLabs' most straightforward test — no fasting, no preparation, results typically within 2-3 business days.

Biomarkers Tested

9
Haematocrit (HCT) %

The percentage of your blood volume occupied by red blood cells. It reflects the balance between red blood cell production and loss, helping diagnose anemia, dehydration, and polycythemia.

Haemoglobin (HGB) g/dL

The iron-rich protein in red blood cells responsible for carrying oxygen throughout your body and returning carbon dioxide to the lungs. Low haemoglobin is the primary marker for anemia and can cause fatigue, weakness, and shortness of breath.

MCV (Mean Corpuscular Volume) fL

The average size of your red blood cells. Small cells (microcytic) suggest iron deficiency, while large cells (macrocytic) may indicate vitamin B12 or folate deficiency. Normal-sized cells with low count suggest chronic disease.

Mean Corpuscular Haemoglobin
Monocytes % %

The percentage of white blood cells that are monocytes. Monocytes are part of the innate immune system and develop into macrophages and dendritic cells in tissues.

pH pH units

Imbalances in gut pH influence short-chain fatty acid production and their effects.

Platelet Count × 10⁹/L

Measures the number of platelets, small cell fragments essential for blood clotting. Low platelets increase bleeding risk, while high platelets may increase clot risk. Important for monitoring clotting disorders and medication effects.

Red Blood Cell Count × 10¹²/L

Measures the number of red blood cells in your blood. Red blood cells carry oxygen from your lungs to every cell in your body. Abnormal levels can indicate anemia, dehydration, or bone marrow disorders.

White Blood Cell Count × 10⁹/L

Measures the total number of white blood cells, your body's primary defense against infection. Elevated levels may indicate infection, inflammation, or immune disorders, while low levels can signal bone marrow problems or autoimmune conditions.
