Researchers at Weill Cornell Medical College have developed a urine test to diagnose and monitor fibrosis or scarring in kidney transplant patients experiencing organ rejection. The simple test could eliminate the need for the many invasive and potentially harmful needle biopsies now used in this situation. Best of all, it would enable doctors to identify and treat fibrosis earlier to avoid complications and damage to the transplant.
