Genotyping of RHD by multiplex polymerase chain reaction analysis of six RHD‐specific exons

Abstract

The multiplex PCR assay is reliable in determining genotypes in people who have the D+ and partial D phenotypes as well as in discovering people with new D variants. Because the multiplex PCR is directed at six regions of RHD, the chance of discrepancies is markedly reduced. The entire analysis can be performed in one reaction mixture, which results in higher speed, higher accuracy, and the need for smaller samples. This technique might be of great value in prenatal RHD genotyping.
