Iohexol measurement
Web2 mrt. 2024 · GFR was measured using iohexol plasma clearance (Omnipaque, 240 mg I/mL, GE Healthcare, Belgium) as the method of reference once in every patient [ 12, 13, 31 ]. After verification of the participant’s identity, a rest of 5 minutes was observed. The syringe with iohexol was weighed before and after the injection to an accuracy of 0.01 g. 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].
