Member organizations

Transplant hospitals, organ procurement organizations (OPOs) and histocompatibility laboratories in the United States all belong to the Organ Procurement and Transplantation Network (OPTN). Voluntary health organizations, such as the American Diabetes Association; general public members, such as ethicists, transplant recipients and donor family members; and medical professional and scientific organizations, such as the American Medical Association also belong. Members play an active role in forming the policies that govern the transplant community.
