Clinical Significance
C4d, a stable split product of classical complement activation, is a marker of antibody-mediated acute allograft rejection as well as hyperacute rejection, acute vascular rejection, acute cellular rejection, and borderline rejection. Detection of C4d has been used diagnostically as a predictor of transplant kidney graft survival and for managing acute rejection.
