Labcorp cystatin c.

Cystatin C is a low-molecular-weight protein that functions as a protease inhibitor produced by all nucleated cells in the body. It is formed at a constant rate and freely filtered by the kidneys. Serum levels of cystatin C are inversely correlated with the glomerular filtration rate (GFR). In other words, high values indicate low GFRs, while ...Cystatin C, first described in 1961 and formally named in 1984, is a non-glycosylated, basic protein encoded by the CST3 gene that is found in virtually all nucleated cells. It is a potent inhibitor of lysosomal proteinases and extracellular inhibitors of cysteine proteases that play a pleiotropic role in human vascular pathophysiology, in ...Cystatin C has been shown to be a reliable and accurate marker of kidney function across diverse populations.

Cystatin C is similar to creatinine in that it is produced at a constant rate and is freely filtered by the glomerulus. However, unlike creatinine, cystatin C is not solely produced in muscles and consequently, not linked to skeletal muscle mass. As a result, serum cystatin C correlates more closely to GFR than serum creatinine, especially in ...
