Glomerular Filtration Rate (GFR) Calculator – Low
Introduction & Importance
Glomerular Filtration Rate (GFR) is a measure of your kidney function. It’s crucial to understand your GFR as it helps monitor your kidney health and detect any potential issues early.
How to Use This Calculator
- Enter your age, creatinine level, and select your gender.
- Click the “Calculate” button.
- Your GFR result will appear below the calculator, along with a chart for better understanding.
Formula & Methodology
The GFR calculator uses the Modification of Diet in Renal Disease (MDRD) formula to estimate your GFR:
GFR (mL/min/1.73m2) = 186 * (Creatinine (mg/dL))^(-1.154) * (Age)^(-0.203) * (0.742 if female)
Real-World Examples
Data & Statistics

| 60-89 | Mildly reduced |
| 45-59 | Moderately reduced |
| 30-44 | Severely reduced |
| 15-29 | Failure |
| 14 or below | Failure |
Expert Tips
- Regularly monitor your GFR to keep track of your kidney health.
- Lifestyle changes, such as a healthy diet and regular exercise, can help maintain good kidney function.
