Typing for RhD should be easy but we all know that is not the case. Sue Johnson will tell us “Why in D world are there “D”screpancies in RhD typing” by describing the basic RHD genetics and biochemistry, discussing the variability of reagent anti-D detecting weak and partial D antigens, and the impact of the methods used to detect RhD antigen.
