Here’s food for
thought. Selective integration of RhD genotyping in laboratory practices
could improve the accuracy of RhD typing results, reduce unnecessary
administration of Rh-Ig in women with a serological weak D phenotype, and
decrease unnecessary transfusion of RhD-negative red cells to recipients with a
serological weak D phenotype
But how often do we see these weak Ds? I
don’t think I’ve ever encountered one that wasn’t actually already known. They
are quite obscure. I this something to be referred to a transfusion centre?
I suppose the clever thing is spotting
the weak expression of the D antigen on the first place.
