Hello all, We are in disagreement among technologists at the hospital that I am working regarding "Match Unrelated Donor samples". Once the MUD sample is received, we did type and screen on the sample and were done until recently. Regardless if the donor sample is RH negative or positive. When the HPC product comes that is from this donor, we do retype on it, immediate spin cross-match with the recipient and issue it to be transfused ( we issue it even if there is ABO disagreement/ discrepancy). Now, my question to you all is, is it necessary to perform weak D (Du) on this sample if it is RN negative? Can you share with me what you ion your hospital. Thank you Simret
