WebApr 13, 2024 · Cystatin C-based GFR equations typically give an estimation of kidney function that is independent of muscle mass and diet [55, 56]. Pediatric eGFR equations also may underestimate GFR since they were derived in children with CKD . Among children with normal birth weight, 22.4% showed decreased eGFR.
WebDec 15, 2024 · Obtaining the serum cystatin C–based estimated GFR is most beneficial when a false-positive decreased estimated GFR is suspected, such as in a patient without known structural kidney disease ... WebSerum 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 Can be used as a confirmatory test for the diagnosis of chronic kidney disease (CKD) in patients with a decreased GFR as estimated from creatinine.
WebThe review also summarizes the history, features and the feasibility of cystatin C measurements as well as the most widely used formulae for the estimation of GFR in … 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 …
WebInterpretation. Cystatin C: Cystatin C inversely correlates with the glomerular filtration rate (GFR), that is, elevated levels of cystatin C indicate decreased GFR. Cystatin C …
