Greetings, This may be just semantics, but I am wondering what you call an antibody that does not have an identified specificity. This could apply to plasma that has demonstrated reactivity in the antibody screen but not the antibody panel or for plasma whose reactivity does not fit a pattern (and all clinically significant antibodies are ruled out). One of our techs calls these 'HLA antibodies' or 'HTLA antibodies' but I tend to call them nonspecifics. I have heartburn over calling these something that I am not sure they are. Anyone else have thoughts on this terminology? Does it really matter? Thanks!
