Paediatric eGFR Equation:
| From: | To: |
The Paediatric eGFR equation estimates glomerular filtration rate (GFR) in children using serum creatinine and height. This simplified formula is specifically designed for paediatric populations and provides a quick assessment of kidney function in children.
The calculator uses the paediatric eGFR equation:
Where:
Explanation: This equation utilizes the direct relationship between height and muscle mass, which correlates with creatinine production, to estimate kidney function in children.
Details: Accurate GFR estimation in children is essential for detecting congenital kidney abnormalities, monitoring kidney function in paediatric nephrology patients, and adjusting medication doses appropriately for age and size.
Tips: Enter height in centimeters and serum creatinine in mg/dL. Ensure accurate height measurement and use fasting creatinine values when possible for optimal accuracy.
Q1: What age range is this equation appropriate for?
A: This equation is typically used for children aged 1-18 years. For infants under 1 year, different equations may be more appropriate.
Q2: How does this differ from adult eGFR equations?
A: Paediatric equations account for the relationship between height and muscle mass, which is more variable in growing children compared to adults.
Q3: What are normal eGFR values in children?
A: Normal eGFR in children varies by age but generally ranges from 90-140 mL/min/1.73m², with higher values typically seen in younger children.
Q4: Are there limitations to this equation?
A: This equation may be less accurate in children with extreme body compositions, malnutrition, or rapidly changing kidney function.
Q5: When should creatinine be measured in children?
A: Morning fasting samples are preferred. Avoid testing after high-protein meals or during acute illness that may affect kidney function.
