When a potential donor registers with us, their cheek swab samples are sent to the DKMS Life Science Lab in Dresden, Germany for testing. At the lab, the sample is analysed to determine the HLA (Human Leukocyte Antigens) characteristics – a fairly complex procedure that can take up to six weeks. After the HLA has been typed, the data is stored confidentially and made available in an anonymous form via the DKMS registry and registries around the world, via the World Marrow Donor Association. Transplant physicians search these registries for matching donors for their patients. Only donor ID, Gender, date of birth and HLA characteristics are shared with the registries. Once you are on the registry, you will be informed and will receive a welcome email from us.
