  1. 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!
  2. Thank you for the interesting plausible insight.
  3. Has anyone encounter the following anomaly? If yes, please enlighten us with possible causes or references which may provide an explanation. Thanks! Patient has history of anti-C and anti-Jkb Antibody screen negative on freshly collected sample. Compatibility testing with C and Jkb negative units were compatible. Sample stored in fridge overnight. Sample was pulled out of fridge to perform crossmatch for add-on orders. All crossmatches were incompatible. Screen repeated and everything was positive. Panagglutination observed on panels. Phenomenon persisted with 3 subsequent samples.
  4. AABB emphasized that if we're using GEL method for crossmatching, there should be another method in place to detect IgM ABO incompatiblity (i.e. tube at IS). If our facility has a computer system in place that detects and alerts ABO incompatiblity between the patient and the donor when selecting the unit for crossmatching (part of our electronic crossmatch process), then does that meet this requirement? If possible, please direct me to any references that relates to this topic. Thank you.
