Creatinine is a waste product cleared by the kidneys, so its blood level is a key marker of kidney function, used to calculate eGFR.
| Measure | Range |
|---|---|
| Men | 0.7–1.3 mg/dL |
| Women | 0.6–1.1 mg/dL |
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.
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.
