I was asked to find out what people are doing about positive DAT's (IgG) that are not associated with transfusion. We receive a few out patient samples that are sometimes positive. We do no further work up. When we receive cord blood speciemens that have a positive DAT, we do not do any further workup unless requested by the physician. Are you guys automatically getting a full patient history and doing an ABID/elution on ALL your positive DAT's, or just the ones that are intended for transfusion? I feel the need to say that we do full work ups on all positive DAT's for transfusion. Thanks Teresa
