The leukopenia is the decreased number of white blood cells or leukocytes, the disease-fighting cells that circulate in the blood.

The normal number of white blood cells varies depending on factors such as age and sex. In an adult male, the number of leukocytes vary from 4500-11000 in each microliter of blood. Children have a slightly higher amount of white blood cells. Leukopenia occurs when the number of leukocytes falls below 5000 leukocytes per microliter of blood due to some internal or external factors.
