[Factors Resulting Correlation and Differences in Renal Function Evaluation Index Using the Serum Cystatin C and Creatinine as Measured by an Enzymatic Method].

We previously reported the association of the estimated glomerular filtration rate (eGFR) calculated from the serum creatinine level (S-Cr) measured using the Jaffe method with the GFR (eGFR) estimated from the serum cystatin C level (CysC). However, few studies have compared the eGFR using the enzymatic method with the eGFR. It is unclear whether there are differences in the results of renal function assessment.
