The Michigan State University Veterinary Diagnostic Laboratory (MSU VDL), a service unit in the College of Veterinary Medicine, is a premier, full-service, fully accredited veterinary diagnostic laboratory for all …
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.
(3) 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 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 In a recent publication, Delanaye et al. (21,22) reviewed the use of iohexol plasma clearance for GFR measurement in both clinical and research settings in depth. Comparisons between iohexol and inulin clearance, as well as with other reference markers, such as iothalamate and radiolabeled tracers, have been discussed exhaustively.
The new iohexol assay from deltaDOT/RVC provides a highly accurate measure of glomerular filtration rate. Because GFR is directly correlated with functional renal mass, quantification of GFR is generally accepted as the best measure of renal function. 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].
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.
J Urol 1991;146:675-679 2. deltaDOT/RVC Iohexol Assay Measure of Glomerular Filtration Rate in cats and dogs. The new iohexol assay from deltaDOT/RVC provides a highly accurate measure of glomerular filtration rate.
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.
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% . 2018-08-28 · Iohexol plasma clearance is the most convenient method for measuring GFR in almost all clinical settings.
This includes when visualizing arteries, veins, ventricles of the brain, the urinary system, and joints, as well as during computed tomography (CT scan). It is given by mouth, injection into a vein, or into a body cavity. Side effects include vomiting, skin flushing, headache, itchiness
All the patients had clearance values < or = 30 ml.min-1.1.73 m-2 body surface; 40 patients < 20 ml.min-1.1.73 m-2 body surface.

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).
2015-04-13 · Additionally, iohexol clearance has been successfully standardized for the assessment of renal function in dogs [8–11] compared with Tc 99m DTPA clearance and inulin clearance.

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.
The project was reviewed and approved by the RVC clinical research and ethical review board, which allowed access to joint iohexol clearance test submission 31 Aug 2020 Specific statistics of agreement were used to test the models against CL2. Keywords: renal function; iohexol plasma clearance; sheep model. We offer two different kits - Inulin (the gold standard) and Iohexol.
