WebThe 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.

Creatinine can also be assayed in urine, for example so as to estimate creatinine clearance (requires blood and 24h urine collection within +/-24h of each other).This is now rarely required as largely replaced by calculation of estimated glomerular filtration rate (eGFR), or by use of the Cockroft-Gault equation as appropriate. cluster raisins vine yellow box
