1. We currently do all antigen typing in tube, but because of our workload, we frequently order antigen negative blood from our supplier. Our expense in this area has been outrageous. I'm thinking about setting up a protocol for using expired antisera, patient sera, etc. for preliminary screening of our donor units, & then using tube method to confirm negatives. Anyone out there doing that? We frequently have students who could perform the preliminary testing. Also considering doing cell separations inhouse to antigen type recently transfused patients but haven't researched that either. 2. We do front type only on our repeat blood types on same samples, but we are not doing electronic xm yet. 3. We don't have any OB patients at this facility. Can't comment on that.
