Complete Blood Count (CBC) is one of the most common and important blood tests. It gives a complete picture of your overall blood health by measuring red blood cells, white blood cells, haemoglobin, and platelets..
It helps detect infections, anaemia, inflammation, bleeding disorders, and many other health conditions.
| Test Parameter | What it Measures | Clinical Importance |
|---|---|---|
| Total Leucocyte Count (TLC) | Total White Blood Cells | Detects infection or inflammation |
| Neutrophils | Absolute Neutrophil Count | First defence against bacterial infections |
| Lymphocytes | Absolute Lymphocyte Count | increases in viral infections |
| Monocytes | Absolute Monocyte Count | increases in Chronic infections & inflammation |
| Eosinophils | Absolute Eosinophil Count | increases in allergies & parasitic infections |
| Basophils | Absolute Basophils Count | Related to allergic reactions |
| Red Blood Cell Count | RBC Count | Oxygen carrying capacity |
| Haemoglobin (Hb) | Oxygen-carrying protein in RBCs | Diagnoses anemia |
| PCV / Hematocrit | Volume of red blood cells in blood | Helps evaluate anemia & dehydration |
| MCV | Average size of RBCs | Differentiates types of anemia |
| MCH | Amount of Hb in each RBC | Detects iron deficiency |
| MCHC | Concentration of Hb in RBCs | Identifies hypochromic anemia |
| RDW-CV | Variation in RBC size | Early indicator of nutritional deficiencies |
| Test Parameter | Normal Range |
|---|---|
| Total Leucocyte Count (TLC) | 4,000 – 11,000 /µL |
| Neutrophils | 40 – 70% (Absolute: 2,000 – 7,000 /µL) |

| Eosinophils | 1 – 4% (Absolute: 50 – 400 /µL) |
| Basophils | 0 – 1% (Absolute: 0 – 100 /µL) |
| Red Blood Cell Count (RBC) | Male: 4.5 – 5.9 million/µL Female: 4.0 – 5.2 million/µL |
| Haemoglobin (Hb) | Male: 13.5 – 17.5 g/dL Female: 12.0 – 15.5 g/dL |
| PCV / Hematocrit | Male: 41 – 53% Female: 36 – 46% |
| MCV | 80 – 100 fL |
| MCH | 27 – 33 pg |
| MCHC | 32 – 36 g/dL |
| RDW-CV | 11.5 – 14.5% |
