“Low white count” means a lower-than-normal number of white blood cells. This makes a person less able to prevent or fight infections. This condition is called leukopenia. Granulocytopenia or neutropenia means a lower-than-normal number of neutrophils, or the white blood cells that kill harmful bacteria.
Patients with low platelet counts have lower-than-normal numbers of platelets (also referred to as thrombocytopenia). This condition, if severe, may cause a person to bruise and bleed more easily.
