samples to be submitted for measurement of iohexol clearance. Dogs were well hydrated at the time of the test, had free access to water for 12 hours before testing, and had no clinical signs consistent with dehydration or hypovolemia. Food was withheld for 12 hours before testing. A single dose of iohexol (Omnipaque 300) was administered

Plasma was analyzed for iohexol by 3 assay methods: chemical , high-performance liquid chromatolography (HPLC) , and inductively coupled plasma emission spectroscopy (ICP) . Plasma exogenous creatinine-iohexol clearance test All dogs were fasted for at least 10 h prior to the test day and fed immediately after ending the sampling period. Procedures: In each cat, GFR was estimated via plasma clearance of iohexol and creatinine. Results of a 1-compartmental model (CL1comp) were calibrated to a trapezoidal method estimate (CLtrap) by use of a correction formula applicable to dogs or humans and standardized to body weight; for iohexol clearance, data were also standardized to extracellular fluid volume (ECFV). clearance compared with creatinine clearance is 1.09 (95% CI, 1.03-1.15). Limitations: Lack of reference standard. Conclusions: This study reveals a signiﬁcant and consistent difference between urinary clearances of iothalamate and iohexol.

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.

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.

clearance compared with creatinine clearance is 1.09 (95% CI, 1.03-1.15). 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 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 purpose of this study was to evaluate simplified methods for iohexol plasma clearance estimation in dogs and cats.

Studies on dogs and cats administered a single intravenous injection of iohexol indicated that a dose of 300 mg I/kg body weight was sufficient for measurement of glomerular filtration rate by

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.

using inulin, creatinine or iohexol [7, 9, 14, 25, 26]. In current veterinary practice, iohexol clearance from plasma is recognized as a standard, clinical available method for assessing GFR in both dogs and cats [15]. However, this test requires sophisticated technology and cannot be used for screening in a primary care practice.

We are very interested in seeing azotaemic, PUPD, dysuric or haematuria patients. There’s often a lot to be gained from further investigation with ultrasonography, renal biopsy and specialist nephropathology, iohexol clearance tests and more.
