Acquired platelet function defects are conditions that prevent clotting elements in the blood called platelets from working as they should. The term "acquired" means these conditions are not present at birth.
Acquired qualitative platelet disorders; Acquired disorders of platelet function
With platelet disorders can affect the number of platelets, how well they function, or both. Any platelet disorder affects normal blood clotting.
Disorders that can cause problems in platelet function include:
Bone marrow disorders are treated with platelet transfusions or removing platelets from the blood (platelet pheresis). Chemotherapy is can used to treat an underlying condition that is causing the problem.
Platelet function defects caused by kidney failure are treated with dialysis or a drug called desmopressin (ddAVP).
