WebNational Center for Biotechnology Information WebIf I am unclear as to whether or not this estimate makes sense, I send out a cystatin C. GFR can be estimated by 70.69 x CysC -0.931. If the two univariate estimates agree within 10%, then that is the eGFR. If there is disagreement, try to see which estimate is likely off. If this is not obvious, you may have to measure GFR in such a patient.

WebUse. Since it is formed at a constant rate and freely filtered by the healthy kidney, cystatin C is a good marker of renal function. Serum concentrations of cystatin C are almost totally dependent on glomerular filtration rate (GFR). A reduction in GFR causes a rise in the concentration of cystatin C. 1,2.

WebGlomerular 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. WebThe biggest drawback with cystatin C as a GFR-marker is that treating a patient with moderate and high glucocorticoid doses will result in an increased synthesis of cystatin C and an increase in cystatin C levels, ...
