(2-5) and is neither secreted nor reabsorbed by the kidney. Extra-renal clearance of iohexol is low and comparable to that for 51Cr-EDTA: extra-renal clearance of iohexol is reported as 0-6 ml/min/1.73m2 (2, 5, 6) compared to 2-4 ml/min/1.73m2 for 51Cr-EDTA (7, 8). Iohexol carries low risk

Key words: glomerular filtration rate, measurement, iohexol, recommendations, Plasma clearance measurement is the protocol of choice: single-sample

Plasma clearance measurement is the protocol of choice as it combines a reliable GFR determination with convenience for the patient. Single-sample protocols Iohexol total clearance was identical to 51Cr-EDTA, whereas urinary clearance of iohexol was slightly higher. Finally, they showed that iohexol was distributed within the extracellular volume [22]. This iohexol distribution pattern applies also to patients with CKD and obese subjects [22–26].

of iohexol clearance. The theoretical concentration at time 0 is calculated from the given dose/distribu-tion volume (estimated from antropometric data) and the sample is obtained at a time-point when the concentration, in the semilog representation, is about half the initial (filled symbols). Iohexol clearance is calculated as dose/area under the curve

All volunteers were informed and signed the consent form. Dual- and multi-sample methods (Cl slope) Based on the one-compartment model, plasma clearance of iohexol was calculated using the slope and the intercept of the regression equation in the final slow clearance. Iohexol clearance also avoids the use of radioactive isotopes, reducing exposure for patients, carers and hospital staff. Therefore the service has several distinct advantages over conventional isotopic clearance methods (Table 1). Iohexol clearance is measured according to a standardized protocol, as described previously [13]. Measuring the glomerular filtration rate in different age groups using iohexol, the protocol from the Belgian iohexol study.

Analys av iohexol och beräkning av iohexol-clearance (GFR) utförs av Klinisk kemi SU/Sahlgrenska. protokoll C-7215 inkluderande patientens aktuella vikt, längd, estimerat absolut GFR baserad på P-Kreatinin och/eller P-Cystatin C enligt metod på www.egfr.se [11], exakta provtagnings-tider på minuten när och given dos skickas till laboratoriet som utför iohexolanalys, beräknar iohexol-clearance och skickar ut svar till beställaren. 2.2 Iohexol clearance protocol 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 intravenously through an IV catheter. Elimination of iohexol from plasma after a single injection.

Iohexol clearance also avoids the use of radioactive isotopes, reducing exposure for patients, carers and hospital staff. Therefore the service has several distinct advantages over conventional isotopic clearance methods (Table 1).

Ten milliliters of iohexol (6.47 g) was injected into the marginal auricular vein and blood samples (3 mL) were collected from the orbital sinus at different points after injection. The plasma clearance of iohexol was described as a simple alternative to inulin clearance for the direct measurement of GFR in 1995. [27] Since then, iohexol clearance has been widely adopted as a gold standard measure of GFR in epidemiologic studies, and as an alternative to more cumbersome and expensive radionuclide measurements [22] [32] .

2020-07-01 · 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.

Urinary inulin clearance is considered the gold standard of glomerular filtration rate (GFR) measurement but plasma clearance of less expensive and more accessible tracers is more commonly performed.

Urinary inulin clearance is considered the gold standard of glomerular filtration rate (GFR) measurement but plasma clearance of less expensive and more accessible tracers is more commonly performed. Many plasma sampling protocols exist but little is known about their accuracy. Here, the study objectives were to compare plasma iohexol and 99mTc-DTPA GFR with varying sampling strategies to the

2015-04-13 · Additionally, iohexol clearance has been successfully standardized for the assessment of renal function in dogs [8–11] compared with Tc 99m DTPA clearance and inulin clearance. This marker has been successfully evaluated in different animals [ 12 – 17 ]; however, there are no reports of its use in studies involving rats. 2020-07-01 · Plasma iohexol clearance has been proposed as an inexpensive method for measuring GFR that could replace estimated GFR in many research projects.
