1. What Is The eGFR Calculator Kidney?

The eGFR Calculator Kidney estimates glomerular filtration rate (GFR) using the CKD-EPI equation from serum creatinine, age, and gender. It provides an accurate assessment of kidney function for general clinical use.

2. How Does The Calculator Work?

The calculator uses the CKD-EPI equation:

Where:

• \( Scr \) — Serum creatinine (mg/dL)
• \( \kappa \) — 0.7 (female) or 0.9 (male)
• \( \alpha \) — -0.241 (female) or -0.302 (male)
• \( age \) — Age in years
• 1.012 — Female multiplier

Explanation: The equation models the non-linear relationship between creatinine and GFR, with gender-specific coefficients for improved accuracy.

3. Importance Of eGFR Calculation

Details: eGFR calculation is essential for detecting kidney dysfunction, monitoring kidney disease progression, and guiding appropriate medical interventions.

4. Using The Calculator

Tips: Enter serum creatinine in mg/dL, age in years, and select gender. Ensure creatinine values are positive and age is within reasonable clinical range (1-120 years).

5. Frequently Asked Questions (FAQ)

Q1: What Is The Normal eGFR Range?
A: Normal eGFR is typically ≥90 mL/min/1.73m². Values below 60 sustained for 3+ months indicate chronic kidney disease.

Q2: How Often Should eGFR Be Measured?
A: Frequency depends on clinical context - annually for screening, more frequently for known kidney disease or high-risk patients.

Q3: What Factors Affect Serum Creatinine Levels?
A: Muscle mass, diet, medications, hydration status, and kidney function all influence creatinine levels.

Q4: Are There Limitations To This Calculator?
A: Accuracy may be reduced in extremes of age, body size, muscle mass, and in populations with rapidly changing kidney function.

Q5: Can This Calculator Be Used For Children?
A: No, this equation is validated for adults only. Pediatric patients require age and height-adjusted GFR calculations.
