A Complete Blood Count measures the main components of your blood — haemoglobin and red blood cells, white blood cells with their types (differential count), and platelets — along with red cell indices such as MCV, MCH, MCHC and RDW.
One of the most commonly ordered tests. It helps detect anaemia, infections, inflammation, bleeding or clotting tendencies and some blood disorders, and is part of routine check-ups, fever work-ups and pre-surgery tests.
Tiredness, weakness, fever, infections, bleeding or bruising; part of every routine health check.
No fasting needed.
For healthy adult males, typical reference intervals include a Red Blood Cell (RBC) count of 4.3 to 5.9 × 10⁶/µL, Hemoglobin (Hb) of 13.5 to 17.5 g/dL, and Hematocrit (Hct) of 38.8% to 50.0%. For adult females, typical values are an RBC count of 3.8 to 5.2 × 10⁶/µL, Hemoglobin of 12.0 to 15.5 g/dL, and Hematocrit of 34.9% to 44.5%. For all adults, the standard White Blood Cell (WBC) count ranges from 4,000 to 11,000 /µL, and Platelets range from 150,000 to 450,000 /µL. Standard red blood cell indices include Mean Corpuscular Volume (MCV) of 80 to 100 fL, Mean Corpuscular Hemoglobin (MCH) of 27 to 33 pg, Mean Corpuscular Hemoglobin Concentration (MCHC) of 32 to 36 g/dL, and Red Cell Distribution Width (RDW) of 11.5% to 14.5%. Exact reference ranges may vary slightly based on laboratory instrumentation, assay methods, and clinical demographics.

Low haemoglobin usually indicates anaemia (often due to iron, B12 or folate deficiency, or blood loss). A high WBC count often points to infection or inflammation. Your doctor will interpret results along with your symptoms.
No fasting is needed. You can eat and drink normally unless your doctor has advised otherwise.
Blood sample taken from a vein in your arm.
Usually within 10–34 hours after the sample reaches the lab. You will receive the report online.
