Weband by some medications (e.g., corticosteroids). In clinical situations where confirmation of the eGFR by serum cystatin C is warranted, equations that combine serum cystatin C and serum creatinine provide a more precise eGFR than equations using serum cystatin C alone. Estimation of GFR from serum creatinine remains the clinical standard ... WebJun 18, 2024 · An alternative to creatinine, cystatin C, is a protein produced in all nucleated cells and distributed in extracellular fluid. It is freely filtered and mostly reabsorbed and catabolized by the proximal tubule. Cystatin C is not affected by muscle mass or diet and is less strongly associated with age, sex, and race than creatinine, but smoking ...
