Platelet antibody screen
Platelet antibody screen-707
Positive screens will reflex to a Platelet antibody identfication
Detect antibodies to HLA Class I antigen, platelet glycoprotein (GP) IV antigens and to polymorphic epitopes on the platelet glycoproteins IIb/IIIa, Ib/IX, and Ia/IIa
Some low titer, low avidity antibodies may not be detected.
Not all antibodies to low incidence HLA class I antigens and platelet-specific antigens may not be detected.
