How do you handle rule outs on a future work up when the patient has a previous known antibody. Currently we require 3 homozygous (if possible) rule out cells for a new antibody, but only one homozygous rule out for all significant antibodies on future work ups. I was wondering what everyone else does in this situation

Thanks for the information. I still would like to know if you have given M - units in the past when the M showed at Coombs phase what do you do when it doesn't show in future testing? We have 2 different view points in my Blood Bank. Once significant always significant or if it's not there don't worry about it

I would like to know how people handle Anti-M when they find it at IAT phase. Do you give antigen negative blood or prewarm it away and consider it not significant? Also if you have patient history of the Anti-M showing at IAT phase and the next time you do a workup it doesn't show how do you handle it. Significant or not?
