Nephrology, dialysis, transplantation : official publication of the European Dialysis and Transplant Association - European Renal Association , 11 (3), 521-525. clearance compared with creatinine clearance is 1.09 (95% CI, 1.03-1.15). Limitations: Lack of reference standard. Conclusions: This study reveals a signiﬁcant and consistent difference between urinary clearances of iothalamate and iohexol.

Many plasma sampling protocols exist but little is known about their accuracy. Here, the study objectives were to compare plasma iohexol and 99mTc-DTPA GFR with varying sampling strategies to the Plasma clearance of iohexol is a key tool to precisely determine glomerular filtration rate (GFR) in clinical research and clinical practice. Despite evidence that iohexol pharmacokinetics are Iohexol Clearance Known as: IOHEXCLR A measurement of the volume of serum or plasma that would be cleared of Iohexol through excretion for a specified unit of time. Röntgenundersökning med kontrastmedel såsom Iomeprol (Iomeron, Jomeron) och Omnipaque (Iohexol, Johexol) stör iohexolanalysen. 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 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 ]. The mathematical model for the drug elimination curve is an open two-compartment system.

iGFR), as described above, also denoted as mGFR (measured GFR). 2015-04-13 · Additionally, iohexol clearance has been successfully standardized for the assessment of renal function in dogs [8–11] compared with Tc 99m DTPA clearance and inulin clearance.
