I can understand an auto Anti-A1 and can see that using a standard triple adsorption the reference lab found no underlying alloantibodies. What makes no sense to me is that they attribute an Anti-A1 in their harvested serum to a donor; the patient has Anti-A1 that they have been unable to adsorb out. I would question their interpretation. How are the transfused cells surviving in your patient?

We QC each rack in use once each day. A new vial is not QC'd when opened until the daily QC is done. We do a QC on each panel when it arrives and check one cell with anti-K and another cell with anti-M. Panels are visually checked for hemolysis before put into use. Heterozygous cells positive and a negative cell are run with other typing reagents once each day and again at the discretion of the tech, sometimes just a positive.
