title: The alloimmune thrombocytopenic syndromes.
abstract: We have summarized five thrombocytopenic syndromes caused by platelet-reactive alloantibodies. Increased awareness of these five syndromes, together with the greater availability of highly-specialized laboratory methods to detect and to characterize platelet-reactive alloantibodies, will lead to their more frequent diagnosis. It is important for the clinician to consider unusual alloimmune thrombocytopenic disorders in clinical settings in which alloantigens that could be limited to just one family could cause important disease (ie, NAT caused by a private alloantigen; theoretically, PAT or TAT related to directed donations of blood or bone marrow). These considerations underscore the need for serological investigations to involve the family members rather than to rely on standard platelet typing donor pools.
