Glossary Term



A blood test performed before a transplant to find out if the specific donor organ to be transplanted is likely to be rejected by the prospective recipient. If the test is positive, the donor and recipient are “”incompatible”” and the transplant is unlikely to be performed with an organ from that donor.
( April 2020)

A blood test to determine compatibility between donor and recipient. A positive crossmatch indicates incompatibility. If the crossmatch is “negative,” then the transplant may proceed. Crossmatching is performed for many organ transplants.
