World Marrow Donor Association (WMDA) is an international association. Worldwide, over 50,000 patients per year are looking for a matched donor outside their family.
Nearly 50% of the patients that find a donor find his or her perfectly matched donor in another country. WMDA works towards a global standardisation by establishing an accreditation programme for organisations that provide blood stem cells for patients in need of a transplant. The accreditation programme ensures the welfare of the donors and high-quality stem cells for patients worldwide.
