Not a Match :o(

I got a response back from the National Marrow Donor Program and I am not a match for the patient I had been contacted about. Here is what they said:

Dear Claudia

Thank you for your involvement in the National Marrow Donor Program. We appreciate the time you took to speak with us, update your health history and donate an additional blood sample in the attempt to be a potential bone marrow/stem cell donor. We were able to perform additional testing for compatibility between you and your potential recipient. The results of the testing indicate that you and the patient do have some differences, but could still be considered a suitable match.

Since the differenes do exist, the physician is requestion that we continue to test and search for other donors who have greater compatibility. At this time no further testing will be requested of you. If the physician cannot find another donor that matches the patient more closely, we may contact you to be a bone marrow or stem cell donor in the future.
