Excellent agreement has been demonstrated between 51Cr-EDTA-clearance and iohexol-clearance estimates (14, 15) (correlation co-efficients 0.92-0.95). Agreement with 99Tc-DTPA methods has not been well-demonstrated. Plasma iohexol clearance measurement is more practicable than urinary

Patienten får ej ha genomgått röntgenundersökning med jodhaltigt kontrastmedel 4 dygn före iohexol-undersökningen eller vara överkänslig mot jodhaltiga kontrastmedel. I det senare fallet rekommenderas krom51-EDTA clearance på Bild- och funktionsanalys i Malmö eller Klinisk fysiologi i Kristianstad.

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 . 2018-08-28 Iohexol clearance is considered a reliable reference method for the determination of GFR. The aim of this study is to, for the first time, evaluate the diagnostic accuracy of plasma cystatin C compared with iohexol clearance in cardiac surgery. Iohexol clearance determinations are now per-formed at numerous hospitals in Sweden. A national quality assurance program, now including 20 different laboratories, was initiated in 1996.

Iohexol is a benzenedicarboxamide compound having N-(2,3-dihydroxypropyl)carbamoyl groups at the 1- and 3-positions, iodo substituents at the 2-, 4- and 6-positions and an N-(2,3-dihydroxypropyl)acetamido group at the 5-position. It has a role as a radioopaque medium, an environmental contaminant and a … Patienten får ej ha genomgått röntgenundersökning med jodhaltigt kontrastmedel 4 dygn före iohexol-undersökningen eller vara överkänslig mot jodhaltiga kontrastmedel.

Nephrology, dialysis, transplantation : official publication of the European Dialysis and Transplant Association - European Renal Association , 11 (3), 521-525. RATIONALE AND OBJECTIVES: We wanted to improve determination of the glomerular filtration rate (GFR) with plasma clearance techniques because the alternative-renal clearance techniques-may involve inaccurate urine sampling or risk of urinary tract infection when bladder catheterization becomes necessary. Therefore, we compared the renal and plasma clearances of iohexol and chromium-51 2012-10-25 2021-02-25 clearance of iohexol. Methods: A total of 46 healthy volunteers and 124 chronic kidney disease (CKD) patients with varying degrees of renal dysfunction received 5 ml iohexol (300 mgI/ml) i.v. and pla sma samples were drawn at 2-, 3- and 4-h post-injection. Plasma-iodine concentrations were detected by high-performance liquid chromatography (HPLC).

Plasma iohexol clearance measurement is more practicable than urinary To measure the accuracy of iohexol clearance using a clinically simple 2-sample single injection technique, a comparison was made in 30 patients with classical continuous infusion techniques for Determination of plasma clearance of contrast agents has been advocated as a means to assess glomerular filtration rate. To evaluate the feasibility of different agents for this purpose, we have compared, in healthy volunteers, the dose dependence of plasma clearance for three contrast media (iohexol, a nonionic agent, and iothalamate and metrizoate, which are ionic substances), with special Renal clearance of creatinine was significantly lower than renal clearance of iohexol (p = 0.0019) and 51Cr-EDTA (p = 0.0001).

that iohexol is excreted unchanged in urine and its renal clearance is almost identical to 51Cr-EDTA clearance. The reliability of GFR determination by iohexol plasma clearance was demonstrated a few years later by Krutzén et al. (19). In 42 patients with normal to moderately impaired renal function, a 5 mL iohexol solution and 4

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 Measuring GFR by iohexol has several advantages: simplicity, low cost, stability and low interlaboratory variation. Iohexol plasma clearance represents the best chance for implementing a standardized GFR measurement protocol applicable worldwide both in clinical practice and in research. glomerular filtration rate, iohexol Plasma iohexol clearance has been proposed as an inexpensive method for measuring GFR that could replace estimated GFR in many research projects. 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. Calculated plasma clearance of iohexol after a single bolus injection correlates well with the “gold standard of renal function” inulin clearance and is recommended as a robust standard for evaluating renal function [ 1, 2, 3 ].
