Beschreibung

General description

Iohexol 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.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Iohexol may be used as an internal standard for the determination of iohexol in human plasma, serum and urine samples by HPLC-UV method. It may also be used as a model compound to analyze the applicability of iohexol for glomerular filtration rate (GFR) measurement by the plasma clearance of iohexol in investigating renal failure.
