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]. WebNovel pediatric glomerular filtration rate (GFR) estimating equations including cystatin C have been proposed to enhance the reliability of GFR calculation. Materials and methods: We examined a pediatric oncologic data set with a total of 363 GFR measurements.

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. WebCystatin C is 13,000-D cysteine proteinase inhibitor produced by all nucleated cells at a constant rate. It is freely filtered at the glomerulus, and then, it undergoes catabolism within the kidney tubules, resulting in no urinary excretion. Thus, the serum level of cystatin C depends on GFR, and it can be used as a measure of kidney function ... 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 ).
