There isn't an exact 'normal' figure for the number of cells in your blood (called your blood count). 'Normal' for a large man wouldn't be the same as for a small woman.

The normal number of WBCs in the blood is 4,500-10,000 white blood cells per microliter (mcL). Normal value ranges may vary slightly among different labs. Some laboratories use different measurements or may test different specimens. Talk to your doctor about your test results.
