Hello. Our institution wants to start stocking low titer group O whole blood. My questions are as follows:
1) What kind of compatibility testing is required. Can an electronic crossmatch be performed? SafeTrace TX will perform ELXM with an "O" to an "A" patient and call it incompatible, whereas when we did an immediate spin crossmatch, we determined it to be compatible.
2) What is your titer cutoff for these low titer whole bloods?
Thank you!
