Red Blood Cell Crossmatch
- The electronic crossmatch
- The emergence of blood bank information systems has given rise to a new crossmatch method called the electronic crossmatch (EXM)
- This can replace the tube method or immediate spin crossmatch
- The immediate spin crossmatch
- When no clinically significant antibodies are detected and there are no previous records of such antibodies, the immediate spin crossmatch is sufficient
- This consists of simply mixing the patient's serum with the donor cells and centrifuging immediately; the absence of agglutination indicates ABO compatibilitiy
- The antiglobulin crossmatch
- This is a complete crossmatch
- It starts with an immediate spin crossmatch followed by an incubation of the patient's serum at 37 C and an indirect antiglobulin test
