What it means
A creatinine test measures the level of creatinine — a waste product made when your muscles break down a substance called creatine — in your blood or urine. Healthy kidneys filter creatinine out of the blood and send it into the urine. When kidneys are not working well, creatinine builds up in the blood. A blood sample is drawn from a vein in your arm. Normal blood creatinine is roughly 0.7–1.2 mg/dL in adults, though it varies by age, sex, and muscle mass. Doctors order this test to evaluate kidney function, diagnose kidney disease, and monitor patients taking medications that can affect the kidneys.
