1. What is the Pediatrics eGFR Equation?

The Pediatrics eGFR equation estimates glomerular filtration rate (GFR) in children using serum creatinine and height. This simplified formula provides a quick assessment of kidney function specifically designed for pediatric populations.

2. How Does the Calculator Work?

The calculator uses the Pediatrics eGFR equation:

Where:

• \( eGFR \) — Estimated glomerular filtration rate (mL/min/1.73m²)
• \( Height \) — Patient height in centimeters (cm)
• \( Scr \) — Serum creatinine in milligrams per deciliter (mg/dL)
• \( 0.413 \) — Constant coefficient for the equation

Explanation: The equation utilizes the relationship between height, serum creatinine, and kidney function to estimate GFR in pediatric patients.

3. Importance of Pediatric eGFR Calculation

Details: Accurate GFR estimation in children is essential for detecting kidney dysfunction early, monitoring chronic kidney disease progression, and adjusting medication dosages appropriate for pediatric patients.

4. Using the Calculator

Tips: Enter height in centimeters and serum creatinine in mg/dL. Both values must be positive numbers. Ensure accurate height measurement for reliable results.

5. Frequently Asked Questions (FAQ)

Q1: What age range is this equation designed for?
A: This equation is specifically designed for pediatric patients, typically from infancy through adolescence.

Q2: How does this differ from adult eGFR equations?
A: Pediatric equations account for growth and development factors, using height as a key variable instead of age, gender, and race used in adult equations.

Q3: What are normal eGFR values for children?
A: Normal eGFR values in children vary by age and body size, but generally range from 90-140 mL/min/1.73m², with higher values in younger children.

Q4: When should this equation not be used?
A: This equation may be less accurate in patients with extreme body compositions, rapidly changing kidney function, or specific medical conditions affecting muscle mass.

Q5: How often should eGFR be monitored in children?
A: Frequency depends on clinical indication, but typically every 3-12 months for stable patients with known kidney disease, or more frequently during acute illness or treatment changes.
