GFR Calculated Low Calculator
GFR Calculated Low: A Comprehensive Guide
Introduction & Importance
GFR, or Glomerular Filtration Rate, is a measure of your kidney function. A low GFR indicates that your kidneys are not filtering blood as well as they should. Understanding your GFR is crucial for managing kidney health and preventing complications.
How to Use This Calculator
- Enter your age, creatinine level, and select your gender.
- Click ‘Calculate’.
- Your GFR and a visual representation will appear below.
Formula & Methodology
The formula used in this calculator is the Modification of Diet in Renal Disease (MDRD) study equation:
GFR (mL/min/1.73m2) = 186 × (creatinine (mg/dL))-1.154 × (age (years))-0.203 × (0.742 if female)
Real-World Examples
| Age | Creatinine (mg/dL) | Gender | GFR (mL/min/1.73m2) |
|---|---|---|---|
| 50 | 1.2 | Male | 75 |
| 60 | 1.5 | Female | 54 |
| 70 | 2.0 | Male | 38 |
Data & Statistics
| GFR (mL/min/1.73m2) | Kidney Function |
|---|---|
| ≥90 | Normal or high |
| 60-89 | Mildly decreased |
| 45-59 | Moderately decreased |
| 30-44 | Severely decreased |
| < 30 | Kidney failure |
Expert Tips
- Regularly monitor your GFR to track kidney health.
- Lifestyle changes can slow the progression of kidney disease.
- Consult your doctor for personalized advice.
