Thanks for your replies! More info related to your comments... A DAT was not done at the time the antibody was identified, because the auto control in gel was negative. The patient has only received A Negative RBCs at our hospital (total of 9 at that time and 3 since then) and no platelets. She is a nursing home resident that was admitted for pneumonia, respiratory failure, and UTI. She has a previous history of coronary bypass surgery where she may have received blood products. Her platelet counts have always been in normal range 300-400s in our records. The DEL idea seems plausible to me. The Anti-D was relatively weak with reactions ranging from w+ to 2+.
