I'm 6 months post-transplant, and I've not tested negative for urine protein since June 11. The amount in my urine has been 30 mg/dl every time it's been checked since then, and I have a lot of foamy urine. I am very worried, although my transplant team and nephrologist do not seem concerned. I did take a 40 mg Lasix a day only when I was short of breath, but I had to take it at least 20 or more days in June and July, and I'm convinced I damaged my new kidney. I stopped Lasix around July 20th. I'm sure my old kidneys are not working at all now so I doubt they are putting out any protein. I'm about to have a breakdown worrying about it 24/7, to the point I'm about to give up.
