Pediatric GFR Formula:
| From: | To: |
The Pediatric GFR Calculation Formula estimates glomerular filtration rate (GFR) in children using serum creatinine and height. This simplified formula provides a quick assessment of kidney function in pediatric populations.
The calculator uses the pediatric GFR formula:
Where:
Explanation: This formula utilizes the relationship between height and creatinine to estimate kidney function, as height serves as a proxy for muscle mass and creatinine production in children.
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 renal function.
Tips: Enter height in centimeters and serum creatinine in mg/dL. Ensure both values are positive and valid for accurate calculation. This formula is specifically designed for pediatric use.
Q1: What age range is this formula appropriate for?
A: This formula is typically used for children and adolescents up to 18 years of age.
Q2: How does this differ from adult GFR formulas?
A: Pediatric formulas often incorporate height as children's body size varies significantly, whereas adult formulas typically use age, gender, and race factors.
Q3: What are normal eGFR values for children?
A: Normal pediatric eGFR values 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 calculation be used in pediatric practice?
A: Use when screening for kidney disease, monitoring known renal conditions, or adjusting medications that require renal dosing in children.
Q5: Are there limitations to this pediatric formula?
A: May be less accurate in children with extreme body habitus, malnutrition, or rapidly changing kidney function. Always correlate with clinical assessment.
