@danab I am 2 1/2 years post-transplant and still get tested monthly. I think that my transplant center will continue that forever, they are very scrupulous about this. I am fortunate, they allow me to use Quest labs which I believe is a national chain, and there is one just about 5 miles down the road from me. I go at 7:00 in the morning and have the results by that afternoon! The hospital labels my tests as "stat".
