In recent years, iohexol has been used as a filtration marker. 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 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.

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

2.2 Iohexol clearance protocol A standard protocol was used for performing the iohexol clearance tests via a limited sampling technique. 23 A single dose of iohexol (Omnipaque™ 300) was administered at 300 mg iodine/kg intravenously through an IV catheter. 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 2018-08-28 · 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 ).

Iohexol-clearance används för bedömning av njurarnas filtrationsförmåga (GFR). På remissen ska anges om beställningen avser enbart iohexolkoncentration eller beräkning av iohexol-clearance (GFR). Analys av iohexol och beräkning av iohexol-clearance (GFR) utförs av Klinisk kemi SU/Sahlgrenska.

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. Cross-sectional investigation. Setting & clearance of iohexol can be estimated in dogs and cats from 1 or 2 blood samples with a reasonable margin with the simplified procedure and to establish an. 31 Aug 2020 Keywords: renal function; iohexol plasma clearance; sheep model The sampling protocol was based on a previous publication in swine [26].

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.
