Cystatin C is produced by all nucleated cells at a constant rate and the production rate in humans is remarkably constant over the entire lifetime. Elimination from the circulation is almost entirely via glomerular filtration. For this reason, the serum concentration of cystatin C is independent from muscle mass and gender in the age range 1 to ...Cystatin C has been around now for over a decade. It is not affected by tubular secretion, it is not affected by race, and it is a better marker of subsequent bad outcomes (see NephJC summary of study from Lees et al, Nat Med 2019).
