Measuring creatinine levels is a way of evaluating kidney function.

What is this test?

This test measures creatinine levels in both the blood and a 24-hour urine sample. Results will provide measurements for serum creatinine, urine creatinine, 24-hour urine creatinine, estimated glomerular filtration rate (eGFR), and creatinine clearance. Creatinine is a waste product produced by the breakdown of creatine in the muscles. Because creatinine is normally excreted from the body through the kidneys, measuring creatinine levels is a way of evaluating kidney function. The creatinine clearance test can help determine the rate at which blood is being carried to the kidneys, as well as how well the kidneys are filtering waste products like creatinine. EGFR is calculated based on a person's creatinine levels. It is an estimate of how much blood per minute is being filtered by the kidneys. A decline in kidney function causes lowered eGFR, which can lead to the buildup of waste products in the blood. The creatinine clearance test is typically ordered as a follow-up to abnormal results on tests such as Blood Creatinine, Comprehensive Metabolic Panel (CMP), or Complete Urinalysis or when someone is experiencing symptoms of a kidney disorder. This test can also be used to monitor people with kidney disease or congestive heart failure.
