Transfusion of DAT+ units safety?

[AR1R1kk]

Any paper available that mentions low/high risk of DAT+ units in male patients? Thank you in advance

Main practical issue from a transfusion perspective is a positive IAT XM.
If RBC given via electronic issue you would be unlikely to ever know the unit was DAT positive.

I always figured that, if it was benign enough in the donor that they met donor requirements, it was likely to be relatively benign in the recipient. Not perfect, of course.

According to rgulations DAT+ Donors blood should not be used for patients and should be discarded or used for any other purpose 

not safe to use DAT+ RBCs

In the UK, NHSBT stopped performing a DAT routinely on donor units some time ago (when I was still working).  If a unit was found to be DAT positive through, for example, an incompatible cross-match, and the unit was returned to the supplier, the unit was tested, and then discarded, and the hospital reimbursed.  If considered necessary, the donor's GP was informed.

However, of course, it is almost certain that many DAT positive units were not discovered, and were transfused to a patient as a result of electronic issue.  I have NEVER heard of a patient having any serious clinical sequalae as a result of this practice.
