In recent years, iohexol has been used as a filtration marker. The substance can be measured in plasma, serum and urine using high-performance liquid chromatography. So far, good agreement has been shown for GFR determined by the classic inulin clearance and by the iohexol plasma clearance. Serum iohexol concentration is measured using deltaDOT High Performance Capillary Electrophoresis technology. Results are then used to calculate clearance of iohexol. This enables GFR to be accurately determined with only 3 samples after application of a correction formula.
Gaspari F, Perico N, Ruggenenti P, et al: Plasma clearance of nonradioactive iohexol as a measure of glomerular filtration rate. J Am Soc Nephrol 1995;6:257-263. 3. There is no simple method to measure glomerular filtration rate (GFR) in swine, an established model for studying renal disease. We developed a protocol to measure GFR in conscious swine by using the plasma clearance of iohexol. We used two groups, test and validation, with eight animals each.

The mean proportional bias of iohexol clearance compared with creatinine clearance is 1.27 (95% CI, 1.20-1.34), whereas that of iothalamate clearance compared with creatinine clearance is 1.09 (95% CI, 1.03-1 In veterinary practice, a routine method for measuring GFR is based on monitoring plasma clearance of iohexol by high‐performance liquid chromatography‐ultraviolet (HPLC‐UV). 6-9 One major limitation is that conventional iohexol clearance protocols require repeated blood sampling over several hours, which is labor‐intensive, time‐consuming, and stressful for the animal. The aim of the present study was to evaluate the performance of plasma clearance of both the dominant exogenous marker iohexol using multiple different sampling protocols and the traditional 2–4-hour 99m Tc-DTPA protocol against urinary inulin clearance determined simultaneously. The overall goal is to identify accurate yet simple-to-perform protocols using iohexol plasma clearance for CKD patients according to important characteristics such as GFR level and edema.
make plasma iohexol clearance a reasonable option for both clinical trials and epidemiologic studies. However, standardization of iohexol assays is lacking, and different sampling protocols may lead to difficulties comparing results across studies. We compared iohexol assays and clearance protocols in

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] . METHODS: Two clearance estimates, two weeks apart, were undertaken in 11 healthy individuals and 26 diabetic patients with minimal to moderate renal impairment (chronic kidney disease stages 1-3). Blood specimens withdrawn at 60, 90, 120, 150, 180 and 240 min post-iohexol were analysed for iohexol. Plasma concentrations of iohexol can be used for measurement of GFR iohexol determinations (urinary clearance; HEXU / Iohexol, Timed Collection, Urine).

In 1984, we introduced iohexol clearance as a method for the determination of glomerular filtration rate (GFR) in clinical work (4). Since then, we have used the method extensively in experimen-tal medicine, and since 1988 it is the standard method for GFR measurements at our hospital. Iohexol clearance is now performed by at least 30

Värdet normaliseras till kroppsytan. 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. Abstract: Plasma clearance of iohexol was evaluated in eight anesthetized California sea lions (Zalophus californianus), without evidence of renal dysfunction, to determine if the one-compartment 2018-08-28 · Iohexol plasma clearance is the most convenient method for measuring GFR in almost all clinical settings. However, in particular situations, where the extracellular volume is increased (ascites, oedema, in intensive care units) the evaluation of urinary clearance may be considered a more reliable procedure ( 21 ). Iohexolclearance ger ett tillförlitligt mått på njurarnas glomerulära filtrationsförmåga (GFR). Används när en precis skattning av GFR är önskvärd såsom inför njurtransplantion, vid dosering av vissa läkemedel eller njurmedicinska frågeställningar.

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 Plasma clearance of iohexol was evaluated in eight anesthetized California sea lions (Zalophus californianus), without evidence of renal dysfunction, to determine if the one-compartment model and the sample protocol used in dogs and cats could be applied to this species. Nonlinearity between samples in 75% (6/8) of sea lions voided those results.
