When I started here we performed elutions on all positive DATs as well, but when I became supervisor we put an end to that. Busy work for no real benefit; like your Pediatrician, they treat the babies the same. Just this year, our Pediatric Subsection decided to start performing cord blood evaluations on all babies of O Pos moms. I know there are several facilities that do the same, but we never have. I asked our Mother/Baby nursing coordinator for the evidence they used to make this change and have had no response. I have never understood the long standing practice of performing the cord blood workups on jaundiced babies either. It seems to me this is all academic and of no real clinical value, but what do I know. Does anyone have any Best Practice guidelines with supporting evidence for any of these practices? The only thing I can come up with is that if the baby turns out to be O as well, that may steer them to investigate alternate explanations for the jaundice; but even then, unless the baby is having continued problems, is the information actually used to determine treatment?
