The American Association of Tissue Banks (AATB) is a professional, non-profit, scientific and educational organization. AATB is the premier standard setting body promoting the safety and use of donated human tissue. The Association was founded in 1976 by a group of doctors and scientists who had started in 1949 our nation's first tissue bank, the United States Navy Tissue Bank.

The overwhelming majority of the human tissue distributed for transplant comes from AATB-accredited tissue banks.

AATB supports the advancement of tissue bank professionals and tissue banking technologies so no one suffers from the lack of donated human tissue.
