Last June I received a pancrease transplant, 5.5 years ago I had a kidney transplant, the kidney is doing fine all creating levels are 1.0 or less. My problem is lipase is jumping around, for example today it was 2227, last week it was 1223, the week before it was 900 and the week before that it was 718, the lowest it has been was 312. I have had 3 biopsies with negative rejection results. They have checked for CMV- negative. Do you know what is causing this erratic behavior?
