Understanding High White Blood Cell Count (WBC) Levels

High white blood cell count, also known as leukocytosis, occurs when the number of white blood cells in your blood exceeds the normal range. This condition can indicate various health issues and requires proper evaluation and management.

What is Considered High WBC?

A white blood cell count above 11.0 * 10^9/L is generally considered high. However, the significance of elevated levels depends on the specific type of white blood cells affected and the underlying cause.
