Creatinine

This test measures creatinine levels in a sample of your blood and/or urine (pee). Creatinine is a normal waste product in your body. It's made when you use your muscles and some of the muscle tissue breaks down.

Normal range

24 published ranges, each from a named source
Female
0.5–1.1 mg/dL (varies by lab)ABIM 0.5–1.1 · LabCorp 0.57–1 mg/dL
Male
0.7–1.3 mg/dL (varies by lab)ABIM 0.7–1.3 · LabCorp 0.76–1.27 mg/dL

These labs do not agree for female: the published adult ranges differ by up to 14%, so the same result can read as normal at one lab and be flagged at another — ABIM 0.5–1.1 · LabCorp 0.57–1 mg/dL. Both are real published values, shown as each lab states them.
