Question

Quizplus · Accepted Answer

ITP is an acquired disorder that results from an isolated deficiency of platelets (i.e., other blood counts are normal). It is believed that platelet destruction and/or inhibition of platelet production is the result of autoantibodies against platelets. Symptoms are related to an inability of the blood to clot and include spontaneous hemorrhages in the skin, mucous membranes, or internal organs.
