The CBC is the most common blood test. It measures your red cells, white cells and platelets — screening for anaemia, infection and clotting problems in one panel.
| Measure | Range |
|---|---|
| Haemoglobin (men) | 13.5–17.5 g/dL |
| Haemoglobin (women) | 12.0–15.5 g/dL |
| WBC count | 4,000–11,000 /µL |
| Platelets | 150,000–450,000 /µL |
| Haematocrit (men/women) | ≈ 41–50% / 36–44% |
It screens for anaemia (low haemoglobin), infection or immune problems (white cells), and bleeding/clotting issues (platelets) — a broad first-line health check.
No — a CBC does not usually require fasting, though your lab may combine it with tests (like glucose or lipids) that do.
