Hi all, we are having a recurring antibody problem on our ECHO and i was wondering if anyone else is see this: ECHO screen strongly pos: 3-4+ PEG screen neg-2+ LISS screen neg cold screen 1-3+ only at 4 degrees DAT neg we have seen 6 of these in the last three weeks, i thought maybe it could be a strip problem but one of them had an ECHO panel run and it was 3-4+ also the only thing we can find is a cold auto at 4 degrees, but i thought ECHO did not detect these!! i am going to call immucor again, but they haven't been too helpful to this point:cries:
