Etymology: Gk, leukos + penes, poor

an abnormal decrease in the number of white blood cells to fewer than 5000 cells per cubic millimeter. The condition may be caused by an adverse drug reaction, radiation poisoning, or pathologic conditions. One or all kinds of white blood cells may be affected. The two most common forms of leukopenia are neutrophilic leukopenia and lymphocytic leukopenia. Also spelled leucopenia. Also called leucocytopenia. Compare aleukia, leukocytosis. See also aplastic anemia, leukocyte. leukopenic, adj.
