Web6 jul. 2024 · The complement-dependent cytotoxicity crossmatch (CDC-XM), a technique that uses T and B lymphocytes to detect donor-specific antibodies (DSA) via activation of the classical pathway of complement, has been widely used for the detection of alloantibodies in transplant patients since it was introduced in the 1960s. WebFor example, a patient could develop antibodies to A2 and A24. In this case A2 and A24 may be considered unacceptable antigens (mismatches) for this patient. If the patient were transplanted with a kidney that had A2 and/or A24, it could be rejected hyperacutely.
