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.
The main cause of a low platelet count in the blood is bone marrow problems, like anemia and leukemia. Other viral infections too, can affect the bone marrowâs ability to produce the adequate supply of platelets. Some of the other common causes of low platelet count are. 1  Pregnancy. 2  The use of certain medication. 3  Hemolytic uremic syndrome.  Thrombotic Thrombocytopenic Purpura 1  (ttp) Autoimmune diseases.  The presence of bacteria in the blood.
