What is the normal range for white cell count?

Question

Hi, could anyone tell me what the normal white cell count would be for someone who is classed as healthy?

Answer 1

The normal range is 4 -11×10 (9)/L. (or 4,500-11,000 per microliter).

Others sources say the normal range as 4.5 -10 ×10 (9)/L (or 4,500-10,000 per microliter).
