WebSerum cystatin C is a non-glycosylated, 13.3-kDa protein belonging to cystatin protease inhibitors. It has shown promise as a replacement for serum creatinine in estimation of GFR.[4,5] After glomerular filtration, it is fully catabolized in the proximal renal tubule and is not returned to blood. WebCystatin C. Cystatin C is 13,000-D cysteine proteinase inhibitor produced by all nucleated cells at a constant rate. It is freely filtered at the glomerulus, and then, it undergoes catabolism within the kidney tubules, resulting in no urinary excretion.
