The measurement of GFR by inulin or sinistrin is still considered the gold standard. However, it has now been largely replaced by other, simpler measures that are approximations of GFR. These measures, which involve clearance of such substrates as EDTA, iohexol, cystatin C, ¹²⁵I-iothalamate (sodium radioiothalamate), the chromium radioisotope ⁵¹Cr (chelated with EDTA), and creatinine, have had their utility confirmed in large cohorts of patients with chronic kidney disease.
