Hello & Welcome Sisiterdonor!
Congratulations on your FANTASTIC NEWS! (Sorry this greeting is belated.)
My younger brother is being evaluated as a donor for me. He told me he had completed the first round of testing the night before my birthday. Honestly, the best b'day gift I've ever received. I'm trying to not get my hopes up too high, just in case, but your story makes me feel sooo happy for you and your brother!!! Thank you for sharing your story.
Wishing all the best for you and your brother!
