The Use of Cystatin C in Estimating Glomerular Filtration Rate

Published:February 25, 2023DOI:


      • Cystatin C is a low-molecular-weight protein found in all tissues in the body.
      • Cystatin C is freely filtered at the glomerulus and metabolized in the proximal tubule.
      • Cystatin C used in equations to estimate the glomerular filtration rate provides a more accurate assessment of kidney function compared with serum creatinine.
