In protocol 1, a fixed contrast material dose (120 mL of iohexol 300) was delivered at an injection rate of 4.0 Iohexol clearance was used to measure GFR.

6 Aug 2020 Creatinine clearance during cimetidine administration for Renal function in the elderly (>70 years old) measured by means of iohexol clearance, serum rate in kidney transplantation: are the K/DOQI guidelines appl

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 2019-11-14 Plasma clearance of iohexol was evaluated in eight anesthetized California sea lions (Zalophus californianus), without evidence of renal dysfunction, to determine if the one-compartment model and the sample protocol used in dogs and cats could be applied to this species. Nonlinearity between samples in 75% (6/8) of sea lions voided those results. 2015-06-04 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.

Iohexol clearance protocol

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] . METHODS: Two clearance estimates, two weeks apart, were undertaken in 11 healthy individuals and 26 diabetic patients with minimal to moderate renal impairment (chronic kidney disease stages 1-3). Blood specimens withdrawn at 60, 90, 120, 150, 180 and 240 min post-iohexol were analysed for iohexol.

13 Apr 2015 Materials and Methods. Twenty-six male Wistar rats weighing 200–350 g were submitted or not to the ARF induction protocol, which was

RESULTS: A high correlation was found between the clearance of iohexol and (99m)Tc-DTPA (r = 0.95). Iohexol är ett röntgenkontrastmedel som praktiskt taget helt utsöndras via glomerulär filtration i njurarna.

In conclusion, plasma clearance of iohexol may well be the best candidate for a common GFR determination method.

Here, the study objectives were to compare plasma iohexol and 99mTc-DTPA GFR with varying sampling strategies to the 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. We compared iohexol assays and clearance protocols in 1.

A newly developed liquid chromatography–tandem mass spectrometry (LC-MS/MS) assay allowed concurrent measurement of iothalamate and iohexol in single urine and plasma specimens that minimized both experimental and bio-logical errors.

Iohexol clearance is now performed by at least 30 På förmiddagen ges en injektion av Iohexol via en venflon. Ett eller flera blodprov tas efter 3–5 timmar, men vid kraftigt sänkt njurfunktion (förväntat värde <20ml/min tas provet dagen efter. Tidsåtgång 4–5 timmar. Vid provtagning dagen efter, tidsåtgång: dag 1 ca 30 min, dag 2 ca 15 min.
