For Mom, we routinely perform Type & Screens on all OB patients. For Baby, we routinely perform cord blood testing (ABO/Rh & IgG DAT) from deliveries of all Rh Negative and Group O moms.
We still perform additional testing when the baby has a positive DAT (IgG testing only). When there is an ABO incompatibility or mom has a current detectable Anti-D due to Rh Immune Globulin, are any facilities still doing more testing on the cord blood? We still do even though the baby is going to be treated the same way. Our protocol is use of a bili light and for a bilirubin to be performed 12 hours after delivery.
I haven't reviewed recent literature on the subject. Curious to see what other facilities are doing for positive DATs when the is not a clinically significant antibody involved.
