CKiD U25 eGFR calculator

Estimate GFR in children, adolescents and young adults less than 25 years old

About

The CKiD Under 25 (U25) GFR estimating equations were developed and validated with data from the Chronic Kidney Disease in Children (CKiD) Study, a longitudinal study of children, adolescents, and young adults from the United States and Canada with chronic kidney disease (CKD). Glomerular filtration rate (GFR) was measured directly by plasma iohexol disappearance. The equations were derived to estimate GFR using either serum creatinine or IFCC-calibrated cystatin C. In internal validation analysis, these equations outperformed 11 other published equations for estimating GFR in children and young adults with CKD.
