Serum Creatinine: normal range & what your result means
Creatinine is a waste product cleared by the kidneys, so its blood level is a key marker of kidney function, used to calculate eGFR.
Typical adult reference range
| Measure | Range |
|---|---|
| Men | 0.7–1.3 mg/dL |
| Women | 0.6–1.1 mg/dL |
What a HIGH result can mean
- High creatinine suggests reduced kidney filtering — from dehydration, medicines or kidney disease
What a LOW result can mean
- Low creatinine is usually harmless (low muscle mass, pregnancy)
Ranges vary by lab. Reference ranges are TYPICAL ADULT values and vary by laboratory, age, sex, pregnancy and the method used. Always read your result against the range printed on YOUR report, and let your doctor interpret it alongside your history.
Frequently asked questions
What raises creatinine besides kidney disease?
Dehydration, a high-protein meal or intense exercise before the test, and certain medicines can raise it. Your doctor looks at the trend and eGFR together.
Can high creatinine be reversed?
If it is from a reversible cause like dehydration or a medicine, yes. Chronic kidney disease is managed to slow progression. Finding the cause is the first step.
