A standard protocol was used for performing the iohexol clearance tests via a limited sampling technique. 23 A single dose of iohexol (Omnipaque™ 300) was administered at 300 mg iodine/kg Cr-EDTA, Inulin, Iohexol (Omnipaque) renalt clearance av sådan markör = GFR Ex: Cl Iohexol = (U Iohexol x Urinvolym)/ P Iohexol Cl Iohexol = GFR. Plasma iohexol clearance has been proposed as an inexpensive method for measuring GFR that could replace estimated GFR in many research projects.

(19). In 42 patients with normal to moderately impaired renal function, a 5 mL iohexol solution and 4 Iohexol is emerging as an excellent alternative to inulin and radioisotopes for clearance studies. Iohexol (Omnipaque) is a low-molecular-weight (821 Da), nonionic, low-osmolar intravenous contrast agent used routinely in the United States for radiologic studies at doses appreciably higher than that required for GFR studies. 32,33 It is almost entirely eliminated through glomerular filtration and is not reabsorbed, secreted, or metabolized by the kidney, thus fulfilling many of the desired Iohexol clearance, Pt- Adress.

Objective: To develop a formula for correcting slope-intercept plasma iohexol clearance in cats and to compare clearance of total iohexol (TIox), endo-iohexol (EnIox), and exo-iohexol (ExIox). Animals: 20 client-owned, healthy adult and geriatric cats. Procedures: Plasma clearance of TIox was determined via multisample and slope-intercept methods. 2015-04-13 Urinary clearance of exogenous creatinine was used to measure GFR for three 30-minute periods occurring between 150 and 240 minutes after iohexol injection.

Nephrology, dialysis, transplantation : official publication of the European Dialysis and Transplant Association - European Renal Association , 11 (3), 521-525. clearance compared with creatinine clearance is 1.09 (95% CI, 1.03-1.15). Limitations: Lack of reference standard. Conclusions: This study reveals a significant and consistent difference between urinary clearances of iothalamate and iohexol.

The iohexol plasma clearance was determined as the ratio between dose of iohexol and AUC (dose/AUC) after applying a correction factor of 0.89 based on a previous publication of our group where we found that the simplified method (one-compartment model) overestimated the GFR in about 11% with respect to the reference method (two-compartment model) 8.

However, lack of standardization for iohexol assays and the use of different protocols such as single- and multiple-sample methods could potentially hamper comparisons across studies.
