WebWhen in steady state, there is an inverse relationship between creatinine/cystatin C and GFR, allowing GFR to be estimated from either using simple equations. Because of the non-linear relationship between creatinine/cystatin C and GFR, relatively small initial increases in these markers represent significant decreases in GFR. WebPlease use the NIDDK-funded CKiD U25 eGFR calculator, 2 an interactive app developed by the hCode team, to calculate eGFR for children and young adults ages 1 to 25. For patients ages 18 to 25, we recommend using both the pediatric 2024 CKiD U25 calculator and the adult calculator. Comparing the estimates from both calculators may provide a ...
