Creatinine Clearance Calculator (Low Serum Creatinine)
Creatinine clearance is a measure of kidney function, indicating how well your kidneys filter waste from your blood. This calculator focuses on low serum creatinine levels, which can occur due to various factors, including muscle loss, dehydration, or certain medical conditions.
- Enter your age, weight, and serum creatinine level.
- Select your gender.
- Click the “Calculate” button.
The formula used in this calculator is the Cockcroft-Gault equation, which estimates creatinine clearance based on age, weight, gender, and serum creatinine level:
Creatinine Clearance (mL/min) = [(140 – Age) * Weight (kg)] / (72 * Serum Creatinine (mg/dL))
For females, the result is multiplied by 0.85 to account for lower muscle mass.
| Range (mL/min) | Kidney Function |
|---|---|
| ≥90 | Normal |
| 60-89 | Mildly reduced |
| 30-59 | Moderately reduced |
| 15-29 | Severely reduced |
| < 15 | Kidney failure |
- Regularly monitor your kidney function, especially if you have diabetes, high blood pressure, or a family history of kidney disease.
- Stay hydrated to help your kidneys function properly.
- Limit your intake of protein, sodium, and phosphorus if you have kidney disease.
What is the normal range for serum creatinine?
The normal range for serum creatinine is 0.6 to 1.2 mg/dL for males and 0.5 to 1.1 mg/dL for females.
