In addition to clerical checks, we do Pre: Visual check, ABO/Rh, hgb, DAT or auto control Post: Visual check, ABO/Rh, hgb, DAT, urine hgb (& urine RBC if positive) BTW, I realize this is not the issue here, but are the non-1st tier tests billed out separately? I can't imagine a haptoglobin cost being recovered. I don't know that we're even getting our hgb & urine testing paid for... Hope your mind's at ease about the extra chemistry testing--
