What does joining a registry involve?

You must be aged between 18 and 50 years old. We will check that there is no medical reason preventing you from being a stem cell donor. After we accept you as a donor, we will take a blood sample, so that we can identify your tissue type for the registry from your DNA - the genetic material our bodies are made up from. We may store the extracted DNA for the sole purpose of undertaking possible newer methods of HLA typing in future.


Patients and potential donors are matched by comparing the white cells in the blood to reveal tissue types. If your tissue type matches with that of a patient needing a transplant, you will be contacted by the BMCDT Marrow Registry. You may also be contacted by the hospital carrying out the marrow transplant. This is a serious commitment and you should consider the full implications for both you and the patient when you first complete the consent form and provide a blood sample for testing. If, however, you do not wish to proceed, you may withdraw at any stage. We would recommend, however, that you do not get registered as a donor, if you are not sure that you will be ready to donate marrow sometime in the future.


If you are identified as the best possible match with a patient, we will ask your permission to pass your details on the hospital undertaking the marrow transplant. You will then have a medical examination and a few more blood tests done to make sure that you are a suitable marrow donor. This may take place either at the BMCDT Marrow Registry office or at the hospital undertaking the transplant.
