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. Iohexol is used for investigation of glomerular filtration. The test material is two samples of serum or plasma with addition of iohexol. The participants can measure the iohexol concentration and calculate the glomerular filtration rate. Frequency: 4/year. Examinations P–Iohexol Pt—Iohexol-clearance, rel Pt—Iohexol-clearance, abs 1.

Iohexolclearance skall därför undvikas inom 4 dygn efter kontraströntgen (vid GFR <20 kan upp till 7 dygn behövas). Iohexolclearance ger ett tillförlitligt mått på njurarnas glomerulära filtrationsförmåga (GFR). Används när en precis skattning av GFR är önskvärd såsom inför njurtransplantion, vid dosering av vissa läkemedel eller njurmedicinska frågeställningar. Iohexol-clearance används för bedömning av njurarnas filtrationsförmåga (GFR). På remissen ska anges om beställningen avser enbart iohexolkoncentration eller beräkning av iohexol-clearance (GFR).

Conclusions: This study reveals a significant and consistent difference between urinary clearances of iothalamate and iohexol. Comparison of studies reporting renal clearance measurements using iohexol versus Iohexol clearance: a gold standard method in routine use Oxford University Hospitals NHS Trust has been routinely offering an iohexol clearance service for the measurement of GFR since June 2011.

Iohexol is used for investigation of glomerular filtration. The test material is two samples of serum or plasma with addition of iohexol. The participants can measure the iohexol concentration and calculate the glomerular filtration rate.

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.

Provtagningsanvisning Iohexolclearance - Region Gävleborg

Median GFR7p was 65.9 (range 6.3–153) mL/min/1.73 m2. 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.
