Understanding Low White Blood Cell Count (WBC) Levels

Low white blood cell count, also known as leukopenia, occurs when the number of white blood cells in your blood falls below the normal range. This condition can increase the risk of infections and requires careful management.

What is Considered Low WBC?

A white blood cell count below 4.0 * 10^9/L is generally considered low. However, the significance of low levels depends on the specific type of white blood cells affected and the underlying cause.
