Cystatin C Equations Categorize Patients Slightly Better Than MDRD eGFR

Slide 19

August 2011

We also calculated MDRD estimated GFR from serum creatinine in the same population. In general, both equations performed reasonably well. However cystatin C. estimated GFR was more specific for identifying patients with a borderline reduction in GFR between 60 and 80 ml/min/1.73m2, shown in the highlighted region on the table. Therefore, cystatin C may have particular utility for providing accurate estimates of GFR among patients with stages 1 and 2 CKD, and for not misdiagnosing normal patients with CKD.
