WebCystatin C can be used to calculate your glomerular filtration rate (GFR). Your healthcare provider can use this to see how well your kidneys are working and if there is a problem. It can also be used to check the progress of your disease, if you have kidney problems. 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 … notes from the underground read onlineWebUse of an age-dependent K with ht/sCr models reduced average bias, notably in young children and young adults; age-dependent cystatin-C models produced similar agreement to using a constant K in children under 18 years, but reduced bias in young adults. notes from the underground study guide
