Clinical Info
Antibodies against some low frequency platelet antigens(HPA-6b, HPA-9b, etc) will not be detected since platelets expressing these antigens are not available. The platelet antibody screen is not designed to identify the platelet alloantigen specificity of antibodies detected or to detect ABO blood group antibodies.
