What happens if my creatinine test results are abnormal?

If your creatinine levels are higher than normal, it may indicate kidney dysfunction or reduced kidney filtration ability. Your doctor may recommend further testing, such as a glomerular filtration rate (GFR) test or a creatinine clearance test, to get a clearer picture of your kidney function. Abnormal creatinine levels could signal chronic kidney disease (CKD), kidney injury, or other underlying conditions. Your healthcare provider will evaluate the cause and discuss appropriate treatment options based on the results.
