Special Info
Samples should be spun down and taken off the clot. Samples should be less than 7 days old when tested. Older specimens are acceptable if they have been frozen.
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.
