@joanaiken, Every year for my annual eval, I undergo a series of tests that monitor the function of my liver and my kidney - as would be expected. The minimum amount of tests includes these basic ones: blood tests, urine samples, a renal function test, ECG, X-rays, abdominal ultrasound, and on protocol years (1,2,3,5,10) a biopsy of my transplanted kidney. I had always thought that the renal function test was because I have a kidney transplant, however, I have met several other transplant folks in that waiting room, and I think the nurse told me that all transplant patients have the kidney function test.
Since you have a liver transplant, do you mind if I ask you, Have you had the renal function tests? (involves passing and measurement of urine quantity, blood draw, dye injection) If so, did the results show evidence of your advancing kidney failure?
