Recently I joined a relatively new Transfusion service where Diamed ABD confirmation donor gel cards (forward) are used for grouping both patients and donors. (Reverse done manually). On the donor cards it is clearly mentioned that D VI plus. When I checked up with other blood bank,s I found that they were using patient cards (DVI negative) for both donors and patients and whenever a donor is found to be negative, weak D testing is done and classified accordingly. No weak D testing done on patients. Nobody wants to use two types of cards in the lab, one for donor and other for patient. That sounds sensible. But, I would like to know whether the antisera supplied by Diamed for weak D testing detects both weak D and partial D.
