Iothalamate study
Web15 jul. 2024 · This diagnostic/prognostic study examines the estimated glomerular filtration rates (eGFR) and iothalamate clearance glomerular filtration rates (iGFR) and the Chronic Kidney Disease-Epidemiology (CKD-EPI) equation race coefficient in the Chronic Renal Insufficiency Cohort study. Introduction Web6 dec. 2024 · Iothalamate can be done using the native form or tagged with radioisotopes. Neither of these methods as currently practiced commonly collect urine; thus, plasma clearances are used [ 23–26 ]. We will discuss the pros and cons of these methods later, but before we discuss, it would be useful to compare how these methods compare with eGFR.
