Plasma clearance measurement is the protocol of choice as it combines a reliable GFR determination with convenience for the patient. Single-sample protocols
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.

Iohexol-clearance används för bedömning av njurarnas filtrationsförmåga (GFR).

In 1984, we introduced iohexol clearance as a method for the determination of glomerular filtration rate (GFR) in clinical work (4). 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

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.
Patients previously enrolled in the SCOPE study, are invited to participate in this additional protocol.

[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 Blood specimens withdrawn at 60, 90, 120, 150, 180 and 240 min post-iohexol were analysed for iohexol. Plasma concentrations of iohexol can be used for measurement of GFR iohexol determinations (urinary clearance; HEXU / Iohexol, Timed Collection, Urine). We compared iohexol assays and GFR measurement protocols in 3 population- based European cohorts. Study Design.
