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:
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.
eGFR by Creatinine = KCreat × (Height / 100) / Serum Creatinine
eGFR by Cystatin C = KCysC / Serum Cystatin C
Average eGFR = (eGFR by Creatinine + eGFR by Cystatin C) / 2
