About Us

Transplant Living is a project of the United Network for Organ Sharing (UNOS), a nonprofit organization that maintains the national Organ Procurement and Transplantation Network (OPTN) under contract with the Health Resources and Services Administration of the U.S. Department of Health and Human Services.

Developing High Quality Content

Developed by UNOS, content for the Transplant Living Web site is designed to support, not replace, the relationship that exists between a patient/site visitor and his/her physician. To help ensure that the Web site is accurate, unbiased and understandable, a dedicated team of transplant candidates, recipients, living donors, healthcare professionals and Web content specialists--from a wide variety of specialties affiliated with different hospitals, schools of medicine and organizations, including the Patient Services Department and the OPTN/UNOS Patient Affairs Committee--have the opportunity to review all content and provide input before it is posted.

UNOS' Mission

UNOS is the leader in the field of transplantation data and research. Our mission is to advance organ availability and transplantation by uniting and supporting its communities for the benefit of patients through education, technology and policy development.

UNOS at Work

UNOS assists the transplant community and the patients it serves in a number of ways:

  • managing the national transplant waiting list, matching donors to recipients 24 hours a day, 365 days a year
  • monitoring every organ match to ensure that organ allocation policies are followed
  • bringing together OPTN members to develop policies that make the best use of the limited supply of organs and give all patients a fair chance at getting the organ they need based on medical criteria—regardless of age, sex, ethnicity, religion, lifestyle, financial, or social status
  • maintaining the database that contains all organ transplant data for every transplant that occurs in the U.S. These data are used to improve transplantation, develop organ-sharing policies, support patient care, and help patients make informed health care choices
  • providing patient-focused information for transplant candidates and their loved ones
  • educating professional groups about their important role in the donation process

UNOS' Partners

UNOS works in partnership with companies, organizations and individuals who recognize the importance of sharing best practice throughout the transplant community.
