HUMAN PLATELET ANTIGEN-1 (ZW) TYPING USING PCR-RFLP

The agreement between human platelet antigen-1 typing with polymerase chain reaction restriction fragment length polymorphism (PCR RFLP) and typing with a serological ELISA method was evaluated. A total of 82 individuals were typed and an absolute correlation was found between the two typing methods. The PCR-RFLP typing method could be clinically useful in a number of immunologically mediated platelet disorders, characterized by severe thrombocytopenia and in early prenatal diagnosis of neonatal alloimmune thrombocytopenia, in which serological methods arc difficult to apply because of their dependency on access to platelets and access to well-characterized anti-HPA-lb antisera.
