The Complete Blood Count (CBC) is one of the most frequently ordered diagnostic blood tests in medicine. It measures the three major cellular components of blood — red blood cells (which carry oxygen), white blood cells (which fight infection), and platelets (which control bleeding) — along with key derived indices. A single CBC provides a comprehensive snapshot of haematological health and is the first test ordered for a vast range of conditions — from anaemia and infections to autoimmune disease and cancer screening. No fasting required.
Key benefits of this package include:
What Does the Complete Blood Count (CBC) Test Measure?
| Level / Result | Possible Interpretation |
|---|---|
| Low Hb + low MCV + low MCH (Microcytic anaemia) | Iron deficiency anaemia (most common) — also thalassaemia trait, anaemia of chronic disease |
| Low Hb + high MCV (Macrocytic anaemia) | Vitamin B12 or folate deficiency — also liver disease, hypothyroidism, certain medications |
| Low Hb + normal MCV (Normocytic anaemia) | Acute blood loss, haemolytic anaemia, aplastic anaemia, anaemia of chronic disease, kidney disease |
| Elevated WBC (Leukocytosis) | Bacterial infection, inflammation, leukaemia, steroid use, physiological stress |
| Low WBC (Leukopenia) | Viral infection, bone marrow suppression, autoimmune destruction, certain medications |
| Elevated neutrophils (Neutrophilia) | Bacterial infection, inflammation, stress, corticosteroids — most common WBC abnormality |
| Elevated lymphocytes (Lymphocytosis) | Viral infection (EBV, CMV, dengue), chronic lymphocytic leukaemia (CLL) |
| Low platelets (Thrombocytopenia) | Dengue fever, ITP, bone marrow failure, hypersplenism, certain medications |
| Elevated platelets (Thrombocytosis) | Reactive (infection, iron deficiency, post-surgery) or essential thrombocythaemia |
| High RDW + low MCV | Mixed deficiency or early iron deficiency — red cells vary significantly in size |
Important Note: CBC parameters must be interpreted as a complete panel — individual values can be misleading without the full picture. Automated CBC results flagged as abnormal are reviewed by a trained haematologist or medical laboratory scientist at Medall. Results must be interpreted by a physician in the context of clinical symptoms, history, and physical examination.
CBC vs. Complete Haemogram: In common clinical usage, CBC and Complete Haemogram are often used interchangeably. Technically, a Complete Haemogram includes CBC parameters plus ESR (Erythrocyte Sedimentation Rate) — giving additional information about systemic inflammation. At Medall, CBC with ESR (Test 38) is also available as a separate panel for patients requiring both haematological and inflammatory markers.
