Glomerular Filtration Rate Estimation (eGFR) ≤25 Years Old

The estimated Glomerular Filtration Rate (eGFR) calculator is an essential tool for assessing kidney function, particularly in children and young adults up to 25 years old. It provides a numerical estimate of how well the kidneys are filtering waste from the blood. This calculator uses both serum creatinine and cystatin C levels, along with age, sex, and height, to provide a more accurate estimation of kidney function compared to using creatinine alone.

eGFR Categories for Children and Young Adults:

• Normal or High: eGFR 90 mL/min/1.73 m² or higher
• Mildly Decreased: eGFR 60-89 mL/min/1.73 m²
• Mildly to Moderately Decreased: eGFR 45-59 mL/min/1.73 m²
• Moderately to Severely Decreased: eGFR 30-44 mL/min/1.73 m²
• Severely Decreased: eGFR 15-29 mL/min/1.73 m²
• Kidney Failure: eGFR less than 15 mL/min/1.73 m²

This eGFR calculator uses equations from the Chronic Kidney Disease in Children (CKiD) study, which are specifically designed for pediatric and young adult populations. It's important to note that while eGFR is a valuable screening tool, it should be used in conjunction with other clinical assessments for a comprehensive evaluation of kidney function.
