National Donor Deferral Registry (NDDR®)

National Donor Deferral Registry (NDDR®) Logo

The National Donor Deferral Registry (NDDR®) helps ensure that deferred donors cannot donate their plasma again.

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.

Please be advised that neither PPTA nor its contract partner can remove a donor’s information from the NDDR®. For further information regarding a deferral, please contact the company/center that placed you on the NDDR® as they are the ones who would have access to more specific information concerning your test results and deferral record. If you do not know which facility you received the reactive test, you may contact Cieloworks using the Information for Donors Found in the NDDR form. CieloWorks can only provide the name and location of the plasma collection center associated with your entry into the NDDR® and the date of entry; they cannot provide specific test result information.

The NDDR® was first 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®.
