Me too! Had one yesterday.....3 cell screen negative and one unit was incompatible. The DAT on the unit was negative too. Patient had an antibody to a low incidence antigen. Would it have killed them? Who knows, but I don't want my initials on that crossmatch tag! Yes, we are still "dinosaurs" at my facility and do full AHG crossmatches on all orders. Our transfusion reaction rate is VERY low! I hope to retire before we do immediate spin and heaven forbid, electronic xm! :o)
