Have been given a few questions by my senior to see if i am going along the right lines, can someone confirm i am before i go back? 1. pan reacting autoantibody / no specificity. -crossmatch by IAT -set up auto -match for Rh phenotype -issue most compatible unit same for cold pan reacting autoantibody? 2. Auto antibody ie C,e etc -C for example, issue C pos units and c neg units as the patient already has C antibodies and we do not want to develop little c? (hope thats the right way round). 3. antibodies with no specificity -IAT crossmatch units that are Rh matched? Any pointers on the above would be great. Thanks
