clearance, and 3) develop sampling parameters and calculation methods for a practical test, based on iohexol clearance, that compares favorably with creatinine clearance in horse foals. Iohexol concentration time data were best described using a 3-compartment open model.
In dogs, 10-point iohexol plasma clearance ranged from 7.8 to 115.4 mL min21 m22. The smallest SDD was obtained for the combination of sampling times 5 and 120 minutes (SDD 5 6.99, mean 520.16). Linear regression analysis between the 10-point reference clearance and the 2-sample clearance (5, 120) yielded
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% . 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 ). After treatment for leishmaniasis, the dog’s azotemia resolved and the GFR improved to 3.30 mL min −1 kg −1 (dog 3b, Tables 2 and 5) which, along with dogs 2, and 5, was in the expected range of 1.840 to 3.712 mL min −1 kg −1 for nine healthy dogs determined by iohexol clearance with a one-compartment model . Serial Iohexol Clearance Determinations At least 2 weeks after iohexol-exogenous creatinine comparisons, 1 normal dog and 2 dogs with reduced renal mass had 3 serial iohexol clearance procedures performed without simultaneous urinary creati-nine clearance procedures. Three or 4 days elapsed between serial determinations.

The results of this study show that the ELISA method provides an accurate measurement of iohexol for the application of obtaining a measured GFR value in felines. Materials and Methods ELISA Iohexol FIT-GFR Kit Components Additional diagnostic tests, such as CBC, blood gas analysis for acid-base status, blood pressure, urine protein:creatinine ratio, iohexol clearance test, survey abdominal radiography, abdominal ultrasonography, contrast studies of the upper and lower urinary tract, cystoscopic examination of the urinary bladder, and renal biopsy may also provide valuable information. Iohexol. Reported normal values for clearance are: Dogs: Weighted mean of 3.1 mL/kg/min, with 95% confidence intervals of the mean of 2.5-3.6 mL/kg/min (von Hendy-Willson and Pressler review). Cats: Weighted mean of 2.5 ml?kg/min, with 95% confidence intervals of 2.2-2.9 L/kg/min (von Hendy-Willson and Pressler review).

iohexol clearance In this test, 300 mg/kg of iohexol, a commonly used radiographic contrast agent, is administered intravenously, and blood samples are typically drawn two, three, and four hours later.1,2 The timing of sample collection is flexible, but the exact time the samples were drawn needs to be accurately recorded so the precise time elapsed since injection can be calculated. Iohexol plasma clearance as a measure of glomerular filtration was determined in 31 dogs and 19 cats after an intravenous (i.v.) bolus injection. All animals were healthy and privately owned. Serial blood samples were taken before and up to 4 h after tracer injection. Iohexol plasma concentration was determined using X-ray fluorescence. 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% .

2 Several methods for measuring GFR have now been validated in dogs and cats, including plasma clearance techniques using non-radioactive markers such as creatinine and iohexol, that are easier 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. In cats, we use the interval reported by Finch et al. in a group of 20 healthy cats (1).

Recently, tests using iohexol, a radiographic contrast agent, have been developed to estimate the GFR in human beings, dogs and cats with results that have been validated by traditional standards. Most testing protocols require a single bolus injection of iohexol, followed by 2 …
