REGGI and the American Rare Donor Program.

The American Rare Donor Program (ARDP) was formed in 1998 to provide rare blood units for patients in need. Members of the program identify rare donors and submit donor information for entrance into a database, REGGI. Information on patients in need of rare blood is also submitted and entered into REGGI. REGGI serves to match phenotypes of registered donors with patients having the respective antibodies. A search process for available units ensues, and blood is provided to the patient. This report provides information on REGGI and its use in the ARDP.
