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 or 3 blood samples obtained over a few hours. Is the test reliable? Yes. Several papers have been published on the use of iohexol to accurately measure GFR. A summary of the approaches that have been taken in measuring GFR, including the use of iohexol, can be found in An overview of glomerular filtration rate testing in dogs and cats by Von Hendy-Willson et al. (3) Iohexol is determined by Inductively Coupled Plasma-Mass Spectrometry (ICP/MS) focusing on the iodine components of iohexol.
Animals Medical records of 119 dogs that had GFR estimation performed via serum iohexol clearance between 2012 and 2017. Methods Prospective study using archived samples. GFR, SDMA, and serum creatinine results were reviewed and submitting practices contacted for outcome data. All dogs included in the study population were non‐azotemic. Clearance was calculated by use of results for all 9 samples (ie, reference method). Results for 3 limited-sample strategies for determination of plasma clearance of iohexol and inulin were compared with results for the reference method.

Three or 4 days elapsed between serial determinations. The GFR of each dog was determined by performing simultaneous iohexol and Gd-DPTA plasma clearances. Blood samples were drawn from the jugular vein at baseline and at 2, 3, and 4 hours post IV administration of 46.9 mg/kg Gd-DTPA, and iohexol at a dose of 300 mg iodine/kg. Iohexol is determined by Inductively Coupled Plasma-Mass Spectrometry (ICP/MS) focusing on the iodine components of iohexol.

(3) Iohexol is determined by Inductively Coupled Plasma-Mass Spectrometry (ICP/MS) focusing on the iodine components of iohexol. Results are supplied as clearance with units of ml/min/kg, as well as the percentage reduction in GFR relative to a cohort of normals from the same species. 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. Röntgenundersökning med kontrastmedel såsom Iomeprol (Iomeron, Jomeron) och Omnipaque (Iohexol, Johexol) stör iohexolanalysen. Iohexolclearance skall därför undvikas inom 4 dygn efter kontraströntgen (vid GFR <20 kan upp till 7 dygn behövas). Iohexol-clearance används för bedömning av njurarnas filtrationsförmåga (GFR).
The MSU VDL offers GFR determination based on single injection of iohexol (300 mg iodine equivalents/kg body weight) performed by the client veterinarian and submission of serum samples taken two, three, and four hours post-dose. Note that patients should be well hydrated and food withheld 12 hours prior to initiation of the GFR test. The iohexol clearance test is a recently developed alternative to detect renal dysfunction. It entails recording an accurate body weight, administering a precise amount of iohexol IV, and accurately timing the collection of blood samples as directed after administration. A paired t test was used to evaluate differences between the 2 plasma clearance methods. Results—A strong linear correlation (r2 = 0.90) was found between GFRs derived from the plasma clearance of Gd-DTPA and those derived from the plasma clearance of iohexol. By use of limits of agreement analysis, almost all (13/14) dogs had Gd-DTPA GFRs
• Assessment of glomerular filtration rate- iohexol clearance test The vast majority of dogs and cats presented for PU/PD will have one of the above conditions identified during the initial evaluation or follow-up testing.

If it is not possible to determine the cause of PU/PD and Other tests include nuclear scintigraphy, clearance tests of endogenous and exogenous creatinine, clearance of chromium-51 EDTA, and the iohexol clearance test.35 Of the aforementioned tests, the iohexol clearance test is probably the most practical and easiest to perform (see the Related Link "Case study: Acute kidney failure from hypotension in a dog" below).
