WebResults: The highest correlation coefficients were found for the cystatin C-based estimates in comparison with creatinine-based estimates or creatinine clearance, even though Bland-Altman plots revealed GFR overestimation for all equations tested. The cystatin C-based Hoek formula exhibited the highest overall precision and accuracy. WebGFR was estimated using the Cockcroft-Gault formula for creatinine clearance and Larsson formula for cystatin C-based GFR. Larsson formula: eGFR = 77.24 × cystatin C −1.2623 The gold standard for measuring GFR viz. inulin clearance, urinary clearance of exogenous radioactive markers ( 125 I-iothalamate and 99m Tc-DTPA (diethylene-triamine ...
WebSerum cystatin C level alone provides GFR estimates that are nearly as accurate as serum creatinine level adjusted for age, sex, and race, thus providing an alternative … WebCystatin C was first suggested as a new marker for GFR in 1979, when it was observed that the plasma level of cystatin C was up to 13 times higher in patients on hemodialysis than in healthy persons. 4 The method developed in 1979 for determination of the cystatin C level in body fluids was enzyme-amplified single radial immunodiffusion. 4 Although this …
WebSep 9, 2013 · Recently, cystatin C, a nonglycosylated protein consisting of 120 amino acid residues encoded by CST3, has gained traction as an alternative marker. 6 Cystatin C is synthesized and secreted at a nearly constant rate by virtually all nucleated cells. Given its 13-kDa size, cystatin C is freely filtered by the glomeruli. WebSep 23, 2024 · Models with cystatin C, age, and sex alone derived from the development data set yielded GFR estimates that were very close to the measured GFR in Black participants (median difference between ...
