Doctors try to determine if a low red blood cell count is caused by increased blood loss of red blood cells or from decreased production of them in the bone marrow. Knowing whether the number of white blood cells and/or platelets has changed also helps determine the cause of anemia.
Medical conditions [edit]. Low white cell count may be due to acute viral infections, such as with a cold or influenza. It can be associated with chemotherapy, radiation therapy, myelofibrosis and aplastic anemia (failure of white cell, red cell and platelet production).HIV and AIDS are also a threat to white cells.Other causes of low white blood cell count include systemic lupus erythematosus, Hodgkin's lymphoma, some types of cancer, typhoid, malaria, tuberculosis, dengue, rickettsial infections, enlargement of the spleen, folate deficiencies, psittacosis, sepsis and Lyme disease.IV and AIDS are also a threat to white cells.
