Common causes of kidney dysfunction after transplantation detected by simple urine test

A new noninvasive urine test can distinguish among different causes of acute kidney dysfunction after transplantation. The test, which is described in a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN), may allow patients to avoid invasive kidney biopsies when their transplanted organ is not functioning properly.

 

When creatinine levels are elevated in the blood of a kidney transplant recipient, it is an indication that the transplanted kidney is not functioning well. There are several reasons for transplant kidney dysfunction, and none of the blood or urine tests can reliably differentiate them.
