My niece has lymphoma. we want to know how we can get tested locally to see if we are a donor match for her next stemcells. she cannot use her own aga?

Should be no problem: The is a national marrow registry. You could go on line to get more information. Another approach would be to have your family ask her oncologist for a local center near you. The evaluation not complicated.

Agree with Dr. B: You may also contact the local blood bank as you would need help from one to collect the stem cells.
