How is creatinine testing used in monitoring kidney transplants?

After a kidney transplant, monitoring creatinine levels is essential for assessing how well the transplanted kidney is functioning. Elevated creatinine levels can signal that the new kidney is not filtering waste properly, potentially indicating rejection or other complications. Regular creatinine testing helps doctors detect any issues early and adjust immunosuppressive medications or other treatments to protect the transplanted kidney. Maintaining stable creatinine levels is a good sign that the kidney is functioning well after transplantation.
