WebSummary Because measurements of GFR are tedious, estimated GFRs based on creatinine or cystatin C are widely used for assessing kidney function. Both measured GFRs and the Staging System for CKD based on GFR have analytical and clinical shortcomings. The advantages of serum creatinine and cystatin C, and eGFR will be discussed. WebCystatin C, another biomarker for estimating the GFR, has less non-GFR variation related to age, sex, and race than serum creatinine. 7 We proposed the use of cystatin C in the same EKFC equation ...
