Clinical Utilities
Since it is formed at a constant rate and freely filtered by the healthy kidney, cystatin C is a good marker of renal function. Serum concentrations of cystatin C are almost totally dependent on glomerular filtration rate (GFR).1,2 A reduction in GFR causes a rise in the concentration of cystatin C.
