Japan Marrow Donor Program (JMDP)

JMDP's guide for international registries states that it was established in 1991 with the cooperation of the Japanese Red Cross Society under a Japanese government initiative and is accredited by WMDA. Donors aged 20 to 54 can be searched for patients. The guide sets out the rules for registries abroad: preliminary search results within one business day, limits on how many JMDP donors a transplant centre may hold at once, and marrow volume caps tied to the donor's haemoglobin to protect the donor. It also states that JMDP has suspended cord blood searches for overseas patients because Japan's revised personal information law no longer allows HLA and similar data to be sent abroad without the donor's consent. Its English home page notes nearly 2,000 patients waiting for transplants.
