Iohexol measurement
Web1 sep. 2024 · The iohexol assay can be performed either by High Performance Liquid Chromatography (HPLC), chemical measurement based on iodine determination, X-ray adsorption spectroscopy [10] or capillary electrophoresis [11]. In clinical practice, HPLC is the most used technique due to their sensitivity, specificity and also flexibility [4], [8]. WebIohexol is a non-ionic, water-soluble contrast agent used as a reference marker to determine the glomerular filtration rate (GFR) which measures the level of kidney function. [ It finds applications in angiographic and urography procedures. [] [ 3] Application

WebThe new iohexol assay from deltaDOT/RVC provides a highly accurate measure of glomerular filtration rate. Because GFR is directly correlated with functional renal mass, quantification of GFR is generally accepted as the best measure of renal function. The test is simple to carry out, safe and provides rapid results.
