WebEstimated glomerular filtration rate (eGFR) calculators provide an estimate of kidney function. eGFR serves as a key marker for chronic kidney disease and is calculated using estimating equations that may not always be precise. Estimates of GFR may be higher or lower than a person’s actual GFR, and uncertainty increases as GFR increases. WebOct 1, 1999 · The concentrations of serum cystatin C were constant in children >1 year, and the nonparametric reference interval was calculated to be 0.51–0.95 mg/L. The present reference interval is slightly lower than in studies reported previously ( 11 ) ( 12 ) ( 16 ). The difference is probably attributable to the use of a particle-enhanced ...

Estimated GFR and Risk of Death — Is Cystatin C Useful?

WebJan 1, 2005 · Cystatin C (cys-C) is a low molecular mass protein that was initially known as inter alia γ-trace, post-γ-globulin, and gamma-CSF. The amino acid sequence of the single polypeptide chain of human cys-C was determined in 1981 [1]. The protein did not display any significant homology with the sequences of any protein at that time.

Estimated GFR and Risk of Death — Is Cystatin C Useful?

WebFeb 24, 2015 · Abstract. Background: Pediatric studies are relatively scarce on the superiority of cystatin C over creatinine in estimation of glomerular filtration rate (GFR).This study measured cystatin C and serum creatinine levels, and compared GFR estimated from these two parameters in patients with chronic renal disease.

WebNov 20, 2024 · Cystatin C (CysC), a cysteine protease inhibitor and low molecular weight protein, is an endogenous marker for glomerular filtration rate (GFR). Thus, the kidney function may be estimated based on CysC [1]. It is produced by all human nucleated cells at a stable rate, as it is the product of a housekeeping gene [2].
