PRE TRANSPLANT - GFR has been fluctuating from 19 to 23 as of Jan 18 when I went for evaluation at the Mayo Clinic for possible transplant. I do not have diabetis or am not obese. Still do not know why I have kidney failure. Have had no hospitalizations or dialysis. Some days I feel better than others. But as of yet no really sick days. I will find out after my final heart stress test on Feb 7th if Mayo will recommend me for a kidney transplant. So far they say I am a good candidate.
