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.

Cancers that affect the blood and bone marrow can also cause a decrease in the count. These types of cancers include leukemia, lymphoma, and multiple myeloma.
