CBC – Complete Blood Count
The most common blood test — evaluates overall health and detects a wide range of disorders including anaemia, infection, and blood diseases.
The Most Ordered Blood Test in the World
A Complete Blood Count (CBC) — also called a Full Blood Count (FBC) — is the single most commonly ordered blood test globally. It provides a snapshot of all three major blood cell types: Red Blood Cells (RBC) that carry oxygen, White Blood Cells (WBC) that fight infection, and Platelets that control bleeding — along with haemoglobin, haematocrit, and cell size indices.
A CBC gives your doctor more diagnostic information per millilitre of blood than almost any other single test. It can simultaneously suggest anaemia, infection, allergy, leukaemia, dengue, and nutritional deficiencies — making it the natural first step in almost any clinical workup.
Parameters Tested
| Parameter | Normal Range (Adult) | What It Measures |
|---|---|---|
| Haemoglobin (Hb) | M: 13–17 g/dL · F: 12–15 g/dL | Oxygen-carrying protein in RBCs |
| RBC Count | 4.5–5.9 million/µL | Number of red blood cells |
| WBC Count | 4,000–11,000/µL | Immune system cells — infection indicator |
| Platelet Count | 1.5–4.0 lakh/µL | Blood clotting cells |
| PCV / Haematocrit | M: 40–50% · F: 36–46% | Percentage of blood volume that is RBCs |
| MCV | 80–100 fL | Average size of red blood cells |
| MCH | 27–33 pg | Average Hb per red blood cell |
| Differential WBC | Neutrophils, Lymphocytes, Eosinophils, Monocytes, Basophils | Type breakdown of white cells |
Why Is This Test Done?
Preparation
No fasting required for a standalone CBC. However, if it is part of a broader panel (e.g., with blood sugar or lipid profile), your doctor may advise 8–12 hours of fasting. Drink plenty of water. Avoid strenuous exercise the night before.
