Cystatin C - Wikipedia

WebCystatin C is a low molecular weight protein (13.36 KD) member of the cystatin superfamily of cysteine protease inhibitors. It is produced by all nucleated cells and exhibits a stable production rate. Cystatin C is freely filtered by the glomerulus and metabolized after tubular reabsorption.26. WebHence, CysCRR could be applied to measure the MM clearance in HF hemodialysis. This study highlights the significance of cystatin C as an important dialysis adequacy marker replacing the conventional markers such as urea and creatinine in HF hemodialysis. Among the middle molecules cystatin C scores over beta-2 microglobulin. WebThe combined serum creatinine-cystatin C equation yields slightly higher accuracy and less bias than equations using serum creatinine alone. Using the combined serum creatinine-cystatin C equation is particularly important when the eGFR value is close to a critical decision point, such as when determining drug dosing or kidney transplant ... dairy milk set finally retail shelves
