Thank you all for the excellent feed back! Malcolm Needs, I realize the importance of the antibody screen to monitor the Mom for atypical antibodies during the pregnancy. But I can’t figure out why we do the DAT @ 28 wks or after delivery, if RhoGAM is indicated. It was set up by the person before me and I’ve never questioned it……..till now. John C. Staley, what you do or did makes a lot of sense to me. What makes the most sense is, “I have discovered over the years that inertia is the most powerful force in the universe. â€We have always done it that way" is often impossible to over come. However, sometimes ‘the way we’ve always done it’ IS the best way. Adiescast, what would do if the mother came in spotting at 11 or 30 weeks and you already knew she was a RhIg candidate? Would you repeat the ABO/Rh. Thanks again :D:D
