RHD Weak D Analysis

New Service Announcement from Carter BloodCare

Current blood banking practices appear to be highly successful in preventing alloimmunization to the D antigen and hemolytic disease of the newborn due to the D antibody. However, the use of Rh immune globulin and Rh negative red blood cells for transfusion can be reduced by identifying weak D genotypes in pregnant women and women of childbearing age.

Genotyping patients serologically identified as weak D or patients with a D typing discrepancy can be useful in determining if administration of RH immune globulin or transfusion of RH negative blood is necessary.
