Agreeing with Malcom, generally give M- units if the patients sample shows anti-M @37C, xm compatible the rest -however if Transfusion reaction was suspected with the others -I would request a sample and investigate/ crossmatch before issuing antigen typed blood to hospital. We are in the unusual situation as covering as a hospital blood bank and a reference lab, I worry greatly as to the identification of such antibodies by labs with limited reagents (as in what really is the antibody!)
