A medical condition where there are fewer white blood cells in the blood than normal, which can make it harder for the body to fight infections.
The doctor diagnosed her with leukopenia after reviewing her blood test results.
Leukopenia → It is formed from "leuko-" (from Greek "leukos", meaning white) and "-penia" (from Greek "penia", meaning deficiency or lack). The term describes a deficiency of white blood cells in the body.
Think of 'white' ('leuko-') and 'deficiency' ('-penia') to remember that leukopenia means a lack of white blood cells.
