GFR Calculation Low
Introduction & Importance
GFR, or Glomerular Filtration Rate, is a measure of your kidney function. A low GFR indicates that your kidneys are not working as well as they should. Understanding your GFR is crucial for managing your health and preventing kidney disease.
How to Use This Calculator
- Enter your age, serum creatinine level, and gender.
- Click the ‘Calculate’ button.
- Your GFR result will appear below the calculator, along with a chart showing your GFR category.
Formula & Methodology
The GFR calculation is based on the Modification of Diet in Renal Disease (MDRD) Study Equation. The formula is:
GFR (mL/min/1.73m2) = 186 * (Creatinine (mg/dL))^(-1.154) * (Age (years))^(-0.203) * (0.742 if female)
Real-World Examples
Case 1
A 45-year-old male with a creatinine level of 1.2 mg/dL has a GFR of 65 mL/min/1.73m2.
Case 2
A 60-year-old female with a creatinine level of 1.5 mg/dL has a GFR of 48 mL/min/1.73m2.
Case 3
A 35-year-old male with a creatinine level of 0.8 mg/dL has a GFR of 105 mL/min/1.73m2.
Data & Statistics
| GFR Category | GFR Range (mL/min/1.73m2) | Kidney Function |
|---|---|---|
| Normal | ≥90 | Normal |
| Mildly Low | 60-89 | Mildly reduced |
| Moderately Low | 30-59 | Moderately reduced |
| Severely Low | 15-29 | Severely reduced |
| Kidney Failure | ≤15 | Kidney failure |
Expert Tips
- Regularly monitor your GFR to track your kidney health.
- Lifestyle changes, such as a healthy diet and regular exercise, can help slow the progression of kidney disease.
- If you have diabetes or high blood pressure, it’s especially important to monitor your GFR.
Interactive FAQ
What is the normal range for GFR?
A normal GFR is 90 or above.
What does it mean if my GFR is low?
A low GFR indicates that your kidneys are not working as well as they should. This could be a sign of kidney disease.
