Histocompatibility Committee

The Histocompatibility Committee applies evolving science and technology in transplant immunology to develop, implement, and inform OPTN bylaws, policies, and clinical guidance for organ donation and transplantation. The Committee provides subject matter expertise to the OPTN for issues related to testing, matching, allocation, personnel qualifications, and other issues in transplant histocompatibility and immunology. The Committee’s goals are to promote patient safety, to strive to continuously improve clinical outcomes, and maximize the use of donated organs.
