Calculating gfr from cystatin c
Web15 jan. 2024 · Cystatin C is often used with creatinine to estimate GFR [ 9, 26 ]. Blood urea nitrogen (BUN), a breakdown product of protein metabolism, is also used to measure how well the kidneys are working [ 27 ]. High Cystatin C Higher than normal cystatin C levels mean that kidney function is likely reduced. WebeGFR-cystatin C (2012) eGFRcr(2024) eGFR-cr-cystatin C (2024) TRACEABLE TO IDMS ?

WebEquations based on the plasma concentration of creatinine or cystatin C generally estimate kidney function (GFR) with sufficient and equal accuracy. This option is currently underutilized in clinical practice. (In usual practice, an eGFR equation is defined as having sufficient accuracy when at least 75% of the estimates fall within ±30% of the measured …
Web3 okt. 2024 · If, for an adult, the GFR estimated by the cystatin C-based equation agrees with that estimated by the creatinine-based equation, no invasive determination of GFR is required and the GFR-estimate representing the mean of the two estimates, (eGFR cystatin C + eGFR creatinine )/2, should be used. Web1 jul. 2006 · Cystatin C (Cys C) has been shown to be an alternative marker of renal function. However, estimation of the glomerular filtration rate (GFR) based on Cys C has received little attention. Recently, several Cys C-based equations were developed in different patient cohorts. To date, the benefit of a Cys C-based GFR calculation in patients after renal …
