Rapid typing for human platelet antigen systems-1, -2, -3 and -5 by PCR amplification with sequence-specific primers.
Typing for human platelet antigens (HPA) is useful in a variety of clinical situations. We developed a method for genotyping for HPA-1, -2, -3 and -5 by means of the PCR amplification with sequence-specific primers (PCR-SSP) technique. Primer sets were designed to allow PCR amplification for all systems using the same assay conditions. Specificity and sensitivity of the method were assessed in a blind quality control study (n = 112). In 111 cases, results obtained by PCR-SSP were identical as compared with PCR-restriction fragment length polymorphism technique. One discrepancy was found to be due to a typing error in the data sheet. The results of the PCR-SSP technique were available within 3 h. We conclude that genotyping based on PCR-SSP enables rapid typing for HPA systems, which makes this technique feasible in most clinical settings where urgent HPA typing is required.
