RHD Genotyping

Test description

This is a PCR-based assay for the identification of many clinically significant RHD variants (alleles) responsible for normal and altered/absent expressions of the RhD human red cell antigen. This test is used to provide the predicted RhD status of a patient when it cannot be determined due to discrepant, weak or inconclusive serological RhD testing.
