What is it?

Leukocytopenia is a decrease in the number of white cell counts in the blood, usually below 4000 white blood cells per microliter of blood. The role of white blood cells is to fight infections. Leukocytes include several types of cells such as neutrophils, lymphocytes, monocytes, eosinophils and basophils; each type has a different function in protecting the body from infections. Leukopenia may be caused due to bone marrow and blood conditions such as aplastic anemia and multiple myeloma, treatment for cancer, congenital disorders such as Kotmass syndrome, infectious diseases such as HIV or hepatitis, autoimmune disorders, malnutrition, medications and sarcoidosis.
