11 February 2017 (Saturday) - Weak D

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.
