Children eGFR Equation:
| From: | To: |
The Children eGFR equation estimates glomerular filtration rate (GFR) specifically for pediatric patients using serum creatinine and height. This formula is particularly designed for children and provides a more accurate assessment of kidney function in the pediatric population.
The calculator uses the Children eGFR equation:
Where:
Explanation: This equation accounts for the relationship between body size (height) and creatinine clearance in children, providing a more accurate GFR estimation for pediatric patients.
Details: Accurate GFR estimation in children is crucial for diagnosing kidney diseases, monitoring kidney function growth and development, and guiding appropriate medication dosing for pediatric patients.
Tips: Enter height in centimeters and serum creatinine in mg/dL. Both values must be positive numbers. Ensure measurements are taken accurately for reliable results.
Q1: What age range is this equation suitable for?
A: This equation is specifically designed for children and adolescents, typically from 1 to 18 years of age.
Q2: Why is height used instead of weight in this equation?
A: Height is used as it provides a more stable and accurate representation of body surface area in growing children compared to weight.
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: Are there any special considerations for creatinine measurement in children?
A: Yes, creatinine levels in children are generally lower than adults and vary with age, muscle mass, and nutritional status.
Q5: When should this equation not be used?
A: This equation may be less accurate in children with extreme body habitus, muscle wasting diseases, or rapidly changing kidney function.
