So I have another question related to cold antibodies, and this came up at work just in the last two weeks: I found a cold antibody in an oncology patient, that was not picked up in gel, but was discovered upon investigation of incompatible immediate spin crossmatch in tube. I reran the screen in tube, and also did a cold panel, and sure enough, the cold was only reacting at room temp and colder. I got the crossmatch to be compatible, prewarmed, and when I did up the paperwork for the units, I put a recommendation that a blood warmer could be used during infusion, just as a heads-up, if the patient's doctor wanted to do that, and then our supervisor sort of slapped my wrist on that one. I was told to never write notes on the transfusion paperwork, and a blood warmer should only be used if the cold antibody is reacting at 37 degrees. What do you all think? I don't see the harm in alerting the people performing the infusion, of things that may be helpful to them, and I just figured why take a chance with an oncology patient, regardless of what the antibody is. Basically I think there's a lot worse offenses that can be had in blood bank, and those were minor in comparison to some, but then, too, this supervisor doesn't always like me all the time and I go through periods where it seems like there's fault-finding just for the glory of power and one-up-manship. . . ..
