Hello, at our facility, we send any positive DAT(we use polyspecific) on cord blood to reference lab for work up/elution for HDN. my question is, what should be done with mother/ should a new type and screen be performed soon after cord blood collected? our procedure says if moms antibody screen is positive, start HDN workup. so should it be a recent antibody screen? or prev prenatal antibody screen result? confusion regarding mother, if antibody screen negative don't send? could an antibody eluted off be missed if moms antibody screen was negative?
I am not original author of procedure, originally placed into service in 2006, biannually reviewed. and I am a recent hire, non blood banker, generalist.
any clarification would be greatly appreciated or an actual cord blood, HDN workup, or positive dat procedure would be great!
