This counts one class of immune cell that circulates briefly, then settles into tissues. There they engulf debris and dead cells and signal to other immune cells. Your doctor checks it as part of the white cell breakdown. It can point to some long-lasting infections or inflammatory conditions.

What is a normal monocyte count blood test range?

A typical adult range is around 2–8%. No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison. Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.
