CertifiedLabsWhat is Cystatin C Test?
Cystatin C is a protein made by cells throughout the body at a steady rate. The kidneys filter it out of the blood, so its level is a useful marker of how well the kidneys are working. The Cystatin C blood test measures this protein to estimate kidney function. It can be especially useful when the standard creatinine-based estimate may be less reliable, such as in older adults or people with low muscle mass.
