2003-01-17 The mGFR will be obtained by the assessment of nonradioactive iohexol clearance. Patients previously enrolled in the SCOPE study, are invited to participate in this additional protocol. Iohexol is an iodinated contrast medium with characteristics similar to those of inulin, being freely filtered by the glomerulus, neither secreted nor reabsorbed by the renal tubules and recovered almost 100% 2.2 | Iohexol clearance protocol A standard protocol was used for performing the iohexol clearance tests via a limited sampling technique.23 Asingledoseofiohexol (Omnipaque™ 300) was administered at 300 mg iodine/kg intrave-nously through an IV catheter. Blood was collected at precisely 2, 3, 2018-08-28 Iohexol is a nonradioactive contrast medium, and its clearance from serum or urine is used to measure glomerular filtration rate (GFR). GFR is the most useful indicator of kidney function and progression of … Abstract: 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 Measuring the glomerular filtration rate in different age groups using iohexol, the protocol from the Belgian iohexol study.

Iohexol clearance protocol

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

Appendix 2. Protocol for procedures for iohexol clearance investigation. Measure height and body mass. Draw a 0-time sample (capillary or venous serum/plasma). Inject exactly 5 ml of iohexol (Omnipaque, Nycomed Amersham, 300 mg I/L) intravenously. After 15 min observation, the patient may leave the laboratory.

Since then, we have used the method extensively in experimen-tal medicine, and since 1988 it is the standard method for GFR measurements at our hospital. 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.

Clinical Biochemistry, 2013.

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.

However, lack of standardization for iohexol assays and the use of different protocols such as single- and multiple-sample methods could potentially hamper comparisons across studies.

Methods Two clearance estimates, two weeks apart, were undertaken in 11 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.

2001-07-01 Iohexol clearance also avoids the use of radioactive isotopes, reducing exposure for patients, carers and hospital staff. Therefore the service has several distinct advantages over conventional isotopic clearance methods (Table 1). Iohexol clearance is measured according to a standardized protocol… 2018-07-11 OMNIPAQUE™ (iohexol) Injection 140 180 240 300 350 140 350 NOT FOR INTRATHECAL USE Section I — Intrathecal Rx ONLY Section observed to allow for normal clearance of the drug from the body (see DOSAGE AND ADMINISTRATION and CLINICAL PHARMACOLOGY). Information for Patients (or if applicable, children) Iohexol is a non-ionic contrast medium, used routinely in the NHS for computed tomography (CT), catheter-based angiography and interventions.
