Myeloproliferative disorders

In myeloproliferative disorders too many blood stem cells develop into one or more types of blood cells. The disorders usually get worse slowly as the number of extra blood cells increases. There are 6 types of chronic myeloproliferative disorders based on whether too many red blood cells, white blood cells, or platelets are being made. Tests that examine the blood and bone marrow are used to detect (find) and diagnose chronic myeloproliferative disorders.
