The laboratory results are entered into the NMDP's registry, a computerized database of potential donors. You will meet with marrow donor counselors at the Blood Center who will help you make an informed decision about donating marrow. The marrow collection process usually does not require an overnight stay in the hospital. The procedure itself is painless, because it is performed under anesthesia. But, for an average of two weeks following the procedure, most donors experience sore hips and some must restrict their activities.
Most donors also report that donating marrow is a very positive experience.
Many marrow donors are willing to donate again in the future. The donated marrow is transfused to the patient, whose diseased cells have been destroyed by intensive chemotherapy. In time, the donated marrow engrafts and begins producing healthy blood cells. Because patients are most likely to find a compatible donor within their own ethnic group, a diverse group of potential donors is needed. Over 2 million volunteers have joined the national registry, but only a small percentage are people of color.
