I have never heard of your references. The main texts for my course includes AABB technical manual by Fung, Harmening's Modern blood banking and transfusion services, and AABB's Standards for blood banking. I am only a part time SBB student, I work full time as a Medical Technologist. This is my final semester. You don't need to show me references I never heard of, I am certain you are right. Mom's with PARTIAL D (NOT WEAK D, WE DON'T TEST WEAK D FOR MOMS) can be typed as Rh positive, but still may form Anti-D when exposed to Rh positive red cells from baby(Modern Blood banking and transfusion services, Harmening, 7th Ed. p. 160).
