Hi, AABB states that weak D testing must only be performed on neonates to determine Rhogam candidacy. That being said, how many facilities are still doing weak D's on all their patients? women of childbearing age?.We are having a problem picking up the weak anti-D reactions on immediate spin. Some of the weak D patients show weak 1+ reactions on immediate spin that become 2-3+ if carried through IgG.Is this a problem for anyone else?I worry that if the techs are missing these reactions, what are they missing on the IgG tube antibody screen and panel reactions. Suggestions are welcome.
