Plasma concentrations of iohexol can be used for measurement of GFR through multiple plasma iohexol determinations following an intravenous bolus injection of iohexol (plasma disappearance), or following a continuous infusion (or subcutaneous injection) of iohexol when used in conjunction with urine iohexol determinations (urinary clearance; HEXU / Iohexol, Timed Collection, Urine).

Intern analyskod. IOHEX Iohexol total clearance was identical to 51 Cr-EDTA, whereas urinary clearance of iohexol was slightly higher. Finally, they showed that iohexol was distributed within the extracellular volume [ 22 ].

Iohexol clearance is considered a reliable reference method for the determination of GFR. The aim of this study is to, for the first time, evaluate the diagnostic accuracy of plasma cystatin C compared with iohexol clearance in cardiac surgery. Platinum clearance had a significant linear relationship to GFR (99mTc-DTPA) (CL (PT) = 2.5 x GFR (99mTc-DTPA)) and to GFR (Iohexol) (CL (PT) = [1.3 x GFR (Iohexol)] + 1.4).

Calculated plasma clearance of iohexol after a single bolus injection correlates well with the “gold standard of renal function” inulin clearance and is recommended as a robust standard for evaluating renal function [ 1, 2, 3 ]. The mathematical model for the drug elimination curve is an open two-compartment system.

IOHEX Iohexol- och Cr-EDTA-clearance ger både absolut och kroppsytenormerad njurfunktion.

Iohexol clearance

Limitations: Lack of reference standard. Conclusions: This study reveals a significant and consistent difference between urinary clearances of iothalamate and iohexol. Comparison of studies reporting renal clearance measurements using iohexol versus Iohexol clearance: a gold standard method in routine use Oxford University Hospitals NHS Trust has been routinely offering an iohexol clearance service for the measurement of GFR since June 2011. The service is widely used by the hospital’s pediatric service, and is used in a variety of clinical situations, including determining renal function in surgical patients and for chemotherapy dosing.

Likaså bör clearance utföras  Iohexol (TiAb) Jacobsson L. A method for the calculation of renal clearance based on a single ('iohexol'/exp OR 'iohexol') AND ('inulin'/exp OR 'inulin'). Även svaren på GFR vid beställning av iohexolbelastning (Pt-Glomerulär filtration [GFR] (Iohexolclearance) kommer att kompletteras med  Studying anephric patients, extra-renal clearance of iohexol was between 2 and 3 mL/min/1.73 m 2 [ 24, 33–35 ]. Studying the difference between plasma and urinary clearances in healthy subjects, the extra-renal clearance of iohexol was between 0 and 6 mL/min/1.73 m 2 [ 22, 26, 30, 36] or 5% [ 25 ].

To evaluate the feasibility of different agents for this purpose, we have compared, in healthy volunteers, the dose dependence of plasma clearance for three contrast media (iohexol, a nonionic agent, and iothalamate and metrizoate, which are ionic substances), with special Renal clearance of creatinine was significantly lower than renal clearance of iohexol (p = 0.0019) and 51Cr-EDTA (p = 0.0001). There were no significant differences between the renal clearances (Clren adv) of iohexol and 51Cr-EDTA or between their plasma clearances (ClAUC-3comp).

Iohexol clearance for the determination of glomerular filtration rate: 15 years' experience in clinical practice. eJIFCC Vol 13 No2: http://www.ifcc.org/ejifcc.htm.

glomerular filtration rate, iohexol Plasma iohexol clearance has been proposed as an inexpensive method for measuring GFR that could replace estimated GFR in many research projects. 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. Calculated plasma clearance of iohexol after a single bolus injection correlates well with the “gold standard of renal function” inulin clearance and is recommended as a robust standard for evaluating renal function [ 1, 2, 3 ]. The mathematical model for the drug elimination curve is an open two-compartment system.
