National Deferred Donor Registry (NDDR)

• The National Deferred Donor Registry (NDDR) is a private industry database used by most U.S. plasma centers. When a donor is deferred, their name may be permanently added to this list, preventing plasma donation at centers nationwide.

• Many donors are surprised to learn that this registry is not government-run. It is maintained by the Plasma Protein Therapeutics Association (PPTA) and relied upon by companies such as Biolife, CSL Plasma, Grifols, and Octapharma.

• A listing in the NDDR often feels like a permanent ban, even when test results were later cleared or when donors did not fully understand their rights.

• Your story may help highlight how the NDDR is used and whether fair appeal options are available.
