Creatinine is one of the most important markers used to assess how well your kidneys are functioning. High creatinine levels in the blood can indicate kidney damage or reduced kidney function — but what’s considered normal?
Let’s understand what your creatinine level really means and when it’s time to consult a nephrologist.
Creatinine is a waste product formed when your muscles use energy. Your kidneys filter it out of your blood and excrete it through urine.
So, the amount of creatinine in your blood gives doctors a good idea of how well your kidneys are doing their job.
| Category | Normal Range (mg/dL) |
|---|---|
| Adult Men | 0.7 – 1.3 mg/dL |
| Adult Women | 0.6 – 1.1 mg/dL |
| Children (1–18 years) | 0.3 – 1.0 mg/dL |
| Elderly | May vary slightly due to muscle loss |
Note: These values can vary slightly between laboratories, depending on their testing methods.
High creatinine (also called hypercreatininemia) can occur due to:
Kidney diseases (e.g., chronic kidney disease)
Dehydration
High-protein diet
Certain medications (like NSAIDs or antibiotics)
Muscle injury or breakdown
Diabetes or high blood pressure-related kidney issues
Low creatinine is less common but may occur in:
Low muscle mass (elderly, malnourished)
Pregnancy
Liver disease
Certain muscle disorders
If your creatinine levels remain consistently above 1.3 mg/dL (in men) or above 1.1 mg/dL (in women), or if your eGFR is below 60, it’s time to see a nephrologist.
They can help identify the cause of your kidney function decline and suggest personalized treatment plans.
