WebClinical practice recommendations suggest ordering cystatin C as a confirmatory test for patients with eGFR cr of 45-59 mL/min/1.73m 2 with uACR <30 mg/g, and in patients for whom the creatinine may be a less reliable indicator of GFR near decision points. eGFR cr-cys provides a more accurate estimate of GFR. 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 … WebCystatin C is made by all nucleated cells, not just muscle. As a result, cystatin C production varies less than creatinine production between individuals, and blood concentrations of cystatin C are fairly similar between individuals who have the same GFR. However, cystatin C has other potential confounders. imagine school town center palm coast fl
