We do not perform antibody screens on babies, only a forward type and a IgG DAT. We use the mom's results when considering transfusion. What is your particular concern for using one screen versus the other? If a mom has always had negative screens, never demonstrated an antibody, great, that was easy. If the mom was previously demonstrating an antibody, even if she is negative now, you would still need to honor that antibody if transfusing mom or baby. To me, it's no different than any other patient. Their current antibody screen is important, of course, but you still need to honor any previous antibody IDs.
