WebThis version does not include race, as do the 2009 and 2012 CKD-EPI creatinine and creatinine-cystatin C equations. See here for more on our approach to addressing race and bias on MDCalc. With the 2024 equation, for the same creatinine value, the 2024 equation will estimate a lower GFR for Black patients and a higher GFR for non-Black patients. WebNov 9, 2024 · Cystatin C is a relatively small protein that is produced throughout the body by all cells that contain a nucleus and is found in a variety of body fluids, including the blood. It is produced, filtered from the blood by the kidneys, and broken down at a constant rate. This test measures the amount of cystatin C in blood to help evaluate kidney ...

WebRationale & objective: In prior research and in practice, the difference between estimated glomerular filtration rate (eGFR) calculated from cystatin C level and eGFR calculated from creatinine level has not been assessed for clinical significance and relevance. We evaluated whether these differences contain important information about frailty. WebCystatin C is a non- glycosylated, basic protein ( isoelectric point at pH 9.3). The crystal structure of cystatin C is characterized by a short alpha helix and a long alpha helix which lies across a large antiparallel, five- stranded beta sheet. Like other type 2 cystatins, it has two disulfide bonds.
WebNov 16, 2005 · Serum cystatin C is a cysteine proteinase inhibitor, that is produced by all nucleated cells in the body, does not undergo tubular secretion, and reflects glomerular filtration rate (GFR)accurately. Normal levels for serum cystatin C are 0.5–1.3 mg/L for children 1–17 years, and 0.5–1 mg/L for adults.
