Kidney Transplantation Committee: Kidney Paired Donation (KPD) Histocompatibility Testing Policies *
This proposal includes requirements for histocompatibility testing on donors and recipients in the OPTN KPD Program. It includes required methods for HLA typing, antibody screenings, and crossmatching; a list of HLA types that must be reported for donors and candidates; and processes that must be followed for identifying unacceptable antigens and in the event of unacceptable positive crossmatches.
