Iohexol is very stable in serum, but we would recommend that any samples sent from outside the UK are shipped chilled or frozen to allow for the longer delivery time.

Background Iohexol clearance is an accurate and precise exogenous marker of glomerular Þltration rate (GFR), but protocols are generally lengthy or require multiple sampling. Shorter or simpler protocols would be more practicable. Methods Two clearance estimates, two weeks apart, were undertaken in 11

Urinary inulin clearance is considered the gold standard of glomerular filtration rate (GFR) measurement but plasma clearance of less expensive and more accessible tracers is more commonly performed. Many plasma sampling protocols exist but little is known about their accuracy.
We developed a protocol to measure GFR in conscious swine by using the plasma clearance of iohexol. We used two groups, test and validation, with eight animals each. Ten milliliters of iohexol (6.47 g) was injected into the marginal auricular vein and blood samples (3 mL) were collected from the orbital sinus at different points after injection.

Background: Iohexol clearance is an accurate and precise exogenous marker of glomerular filtration rate (GFR), but protocols are generally lengthy or require multiple sampling. Shorter or simpler p
The mean proportional bias of iohexol clearance compared with creatinine clearance is 1.27 (95% CI, 1.20-1.34), whereas that of iothalamate clearance compared with creatinine clearance is 1.09 (95% CI, 1.03-1 In veterinary practice, a routine method for measuring GFR is based on monitoring plasma clearance of iohexol by high‐performance liquid chromatography‐ultraviolet (HPLC‐UV). 6-9 One major limitation is that conventional iohexol clearance protocols require repeated blood sampling over several hours, which is labor‐intensive, time‐consuming, and stressful for the animal. The aim of the present study was to evaluate the performance of plasma clearance of both the dominant exogenous marker iohexol using multiple different sampling protocols and the traditional 2–4-hour 99m Tc-DTPA protocol against urinary inulin clearance determined simultaneously. The overall goal is to identify accurate yet simple-to-perform protocols using iohexol plasma clearance for CKD patients according to important characteristics such as GFR level and edema.

make plasma iohexol clearance a reasonable option for both clinical trials and epidemiologic studies. However, standardization of iohexol assays is lacking, and different sampling protocols may lead to difficulties comparing results across studies.

There is no simple method to measure glomerular filtration rate (GFR) in swine, an established model for studying renal disease. We developed a protocol to measure GFR in conscious swine by using the plasma clearance of iohexol. We used two groups, test and validation, with eight animals each. Ten milliliters of iohexol (6.47 g) was injected into the marginal auricular vein and blood samples The plasma clearance of iohexol was described as a simple alternative to inulin clearance for the direct measurement of GFR in 1995. [27] Since then, iohexol clearance has been widely adopted as a gold standard measure of GFR in epidemiologic studies, and as an alternative to more cumbersome and expensive radionuclide measurements [22] [32] .
GFR was measured as plasma iohexol clearance in all three cohorts. Multiple- sample protocols were used in AGES-Kidney and BIS, and a single-sample protocol
The substance can be measured in plasma, serum and urine using high-performance liquid chromatography. So far, good agreement has been shown for GFR determined by the classic inulin clearance and by the iohexol plasma clearance.
Plasma clearance is determined after intravenous administration of 5–10 mL of the In patients with large oedema or ascites, urinary clearance protocols should be employed. In conclusion, plasma clearance of iohexol may well be the best candidate for a common GFR determination protocols based on iohexol plasma clearance. Animals: Seventeen CKD-positive and 23 CKD-negative dogs of different breeds and sex. Methods: Prospective nonrandomized study. Plasma iohexol was measured 5, 15, 60, 90, and 180 minutes after injection.
