The National Donor Deferral Registry (NDDR®) is a database of permanently deferred plasma donors in North America. It is one of many voluntary, self-regulating initiatives taken by the source plasma collection industry and is an important component of the industry-driven safety measures that help ensure the safety of the final therapies.
The NDDR® first was made available to all blood and source plasma facilities in December 1993. All donors who test "reactive" for the viral agents for HIV, HBV, and HCV are added to the NDDR® and are permanently prohibited from donating plasma at participating licensed and industry-certified centers in the U.S. and Canada. Cieloworks, a valued partner of PPTA, is responsible for the administration and customer support services of the NDDR®.
