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.

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.

but standard blood tests are normal, a more specific test of kidney function, the GFR test, can be performed. There are several ways to measure GFR, including iohexol clearance, creatine clearance, and renal scintigraphy (nuclear scan). The iohexol clearance test is performed by giving an intrave-

If such a test could be developed, it would allow veterinarians to 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. 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 is widely available as radiographic contrast material, but iohexol assays are available only in a limited number of laboratories (eg Royal Veterinary College UK, Michigan State University USA). Technique (intrinsic) limitations. Multisample plasma clearance techniques are labor-intensive and expensive. It does not require any specialized equipment or urine collection and can be completed in four hours.36,37 (Iohexol measurement for the iohexol clearance test is available at the Diagnostic Center for Population and Animal Health, Michigan State University, 4125 Beaumont Road, Lansing, MI 48910-8104; phone: (517) 353-1683; FAX: (517) 353-5096; www.animalhealth.msu.edu.) Each dog received each CT technique 6–8 weeks apart starting with bolus tracking with each dog receiving 2 ml/kg iohexol (300 mgI/ml – total dose 600 mg/kg) (Omnipaque, Adcock Ingram Healthcare, Bryanston South Africa) administered with a pressure injector at 3 ml/sec. Test bolus dogs received a manually injected test bolus of iohexol 300 mgI/ml (15% or 0.3 ml/kg of the total dose of 2 ml/kg) followed by an additional dose of 2 ml/kg administered with a pressure injector at 3 ml/sec. Serum iohexol concentration is measured using deltaDOT High Performance Capillary Electrophoresis technology.

• 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 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. 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. clearance compared with creatinine clearance is 1.09 (95% CI, 1.03-1.15).

Studies have shown that GFR measurement by plasma clearance of iohexol (plasma iohexol clearance test [PICT]) is comparable with urinary clearance of exogenous creatinine in healthy cats and dogs 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. 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.

The purpose of this study was to evaluate simplified methods for iohexol plasma clearance estimation in dogs and cats. Serial blood samples were taken before and 5, 20, 40, 60, 80, 100, 120, 150, 180, and 240 minutes after a bolus injection of iohexol in 51 dogs and 25 cats. Iohexol plasma concentration was determined with X-ray fluorescence.

In some cases, poor arterial visualization has been attributed to patient movement.
