Hi everyone, A few years ago many Transfusion Services started performing an immediate spin crossmatch in addition to IgG gel crossmatch even though the Transfusion Service had a validated computer system to detect ABO incompatibility. Is anyone not doing an immediate spin crossmatch in addition to IgG gel crossmatch when the patient has a clinically significant antibody (or history of) when you have a validated computer system to detect ABO incompatibility? If so, why not? has an inspector had a problem with this? what have you based your decision (CAP, AABB)? thanks for your input JB
