Cystatin C is a small protein[1] that is produced by all cells that contain a nucleus (i.e. the majority of cells in the body). In healthy people, it is produced and destroyed at a constant rate and is found in a variety of body fluids such as blood, spinal fluid, and breast milk.

Cystatin C is filtered out of the blood by the glomeruli[2], which are clusters of tiny blood vessels in the kidneys that allow water and dissolved substances and wastes to pass through their walls while retaining blood cells and larger proteins. What passes through the walls of the glomeruli forms a filtrate fluid. The kidneys reabsorb cystatin C, glucose and other substances from this fluid. The remaining fluid and wastes are carried to the bladder ...
