My transplant team is very picky and that's why my nephrologist uses them. I've only tested one live donor and I think they are too picky. He was perfectly healthy, but he had a small amount of protein in his 24-hr urine. Their cut-off is 150 mcg and he spilled 168 mcg. Now, I know that could be "the start" of kidney disease and I have told him to go get checked by a nephrologist. But to hear that their cut-off "used" to be 200 (and there are a lot of hospital's who's cut-off is still 200) and they lowered it still urks me a little. My 2nd donor will be admitted for testing on the 24th. If he is not eligible then my 1st donor will definitely go to a nephrologist and get a kidney biopsy. If that's negative we will attempt to resubmit him.
The testing
in my opinion is fairly easy. The age cut-off for my hospital is 60 yo for donation and 76 yo for a recipient. Over the age of 45 they have to have a colonoscopy, but that's the only invasive test I know of. Everything else is blood work (lots of blood work), urine, chest x-ray, and cardiovascular. I think that's it. They have to be in good general health otherwise, as well (teeth, skin, preferably non-smoker, etc.). I hope your brother is doing well and makes whatever decision is best for him.
Also, my coordinator says she's never had a donor come back with kidney problems. They have a follow-up following hospital discharge and she never sees them again. Look at
www.livedonorsonline.com. You will find alot of donors with both good and bad experiences. I find that a helpful site.
Good Luck!
