Serum Creatinine: normal range and what it means
Short answer: The normal serum creatinine range is 0.7 – 1.3 mg/dL for men and 0.5 – 1.1 mg/dL for women. In SI units that is about 62 – 115 µmol/L for men and 44 – 97 µmol/L for women. Labs differ a little, so also check the range printed on your report.

Normal range
This marker’s healthy range depends on sex and age.
| Normal range | Men | Women |
|---|---|---|
| Low | < 0.7 mg/dL | < 0.5 mg/dL |
| Normal | 0.7 – 1.3 mg/dL | 0.5 – 1.1 mg/dL |
| Elevated | 1.3 – 1.7 mg/dL | 1.1 – 1.6 mg/dL |
| High | ≥ 1.7 mg/dL | ≥ 1.6 mg/dL |

What it measures
Creatinine is a waste product from muscle metabolism. Healthy kidneys filter it out, so its level indicates how well your kidneys are working.
What moves it
Kidney function (primary), muscle mass, hydration and some medications.
How to bring it into range
Staying hydrated, controlling blood pressure and blood sugar, and avoiding kidney-stressing drugs.
How fast it responds
Acute changes within days; chronic changes over months to years.

Common questions
- What is the normal serum creatinine range?
- The normal serum creatinine range is 0.7 – 1.3 mg/dL for men and 0.5 – 1.1 mg/dL for women. In SI units that is about 62 – 115 µmol/L for men and 44 – 97 µmol/L for women. Labs differ a little, so also check the range printed on your report.
- What does a high Serum Creatinine mean?
- A value above the reference band means Serum Creatinine is outside the range typical for a healthy adult. A single reading is rarely conclusive on its own — what matters is the trend across draws and the other markers around it, which is why HealthOS reads the whole panel together rather than one number at a time.
- How do I improve my Serum Creatinine?
- Staying hydrated, controlling blood pressure and blood sugar, and avoiding kidney-stressing drugs.
