UNOS brings together medicine, science, public policy and technology to facilitate every organ transplant performed in the United States. Every day, UNOS assists transplant doctors, patients, and members of the public by helping to ensure that organs are procured and distributed in a fair and timely manner.

• The Organ Center matches donors to recipients and coordinates the organ-sharing process 24 hours a day, 365 days a year.
• The Technology group maintains the databases that contain all clinical transplant data for every transplant event that occurs in the U.S.
• The Research department performs data analyses, fills data requests, produces the Annual and other data reports, and authors authoritative publications.
• UNOS monitors every organ match to ensure adherence to UNOS policy, and works with the Board of Directors to develop equitable policies that maximize the limited supply of organs.
• Professional Services offers support to members of the transplant community; these services include seminar planning, providing educational programs and workshops, and much more.
• Patient Services provides assistance to patients, family members and friends, and sets professional standards for efficiency and quality patient care.
• As the founding member of the Donate Life America, UNOS raises public awareness about the importance of organ donation and works to keep patients informed about transplant issues and policies.
• UNOS offers comprehensive conference planning to assist organizations within the transplant community.
