I rotate once every 6 weeks into Blood Bank but have a lot of experience in Blood Bank. We have been using the ECHO about 9 months and I have had very little hands-on experience with it. We recently had 3+ reactions in 2 of 3 screening cells. Tube testing for LISS and PEG were negative. We did an ECHO panel (we're not validated to report panels yet) and got an almost perfect Anti-Jka. DAT was weak positive and eluate demonstrated the Anti-Jka. Did not have enough specimen for tube panel although I'm pretty sure that would have been negative. Is anyone having similar experiences and wondering how many Anti-Jka's our tube testing has missed???
