How to Check My Name in the National Donor Deferral Registry

The National Donor Deferral Registry (NDDR) is a database that stores the names and information of North American blood plasma donors that have been given a status of “permanently deferred” when it comes to plasma donation. The database is a self-regulation move made by the plasma collection industry to protect recipients of donated plasma from receiving plasma that is infected with Hepatitis B, C or HIV 1 or 2. The NDDR was established in 1993 and can be accessed online by all plasma donation facilities in North America. Fifth Dimension (5D) is the company which administers and maintains the NDDR.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Note when and where you donated blood plasma. Consider whether you have received a positive diagnosis for Hepatitis B Surface Antigen (HbsAg), the antibody to Hepatitis C (anti-HCV) or an antibody to Human Immunodeficiency Viruses 1 and 2 (anti-HIV 1/2).
