WebIothalamate sodium has a MW of 637 Da. It can be used as 125 I-radiolabeled or without radioactive label, its plasma concentration then being assessed by x-ray fluorescence or by HPLC or, more recently, by capillary electrophoresis. It is only minimally bound to proteins, and its renal handling has some similarities with that of inulin. WebIn the MDRD study, GFR was measured as the urinary clearance of 125I-iothalamate (iGFR) after a subcutaneous injection of 35 microcuries without simultaneous administration of epinephrine. GFR was calculated as the ratio of time-weighted averages of urine excretion rates of the iothalamate marker and the serum concentrations of the marker …

WebNursing Mothers: Iothalamate salts are excreted unchanged in human milk. Although it has not been established that serious adverse reactions occur in nursing infants, because of the potential for adverse reactions, caution should be exercised when Cysto-Conray II is administered to a nursing woman. WebStudies of Individual Renal Function Serum creatinine, iothalamate clearance, and other estimates of GFR are measures of total renal excretory function and do not address changes within each kidney. They may be influenced by numerous factors, including body mass, protein intake, and age. WebBackground: Nonradiolabeled iothalamate clearance is an accurate way to determine glomerular filtration rate (GFR). Objectives of this study are to define the normal range of nonradiolabeled iothalamate clearance in potential kidney donors and assess whether creatinine-based GFR estimates are accurate in this population. snow removal huntsville ontario
