The GFR of 96 children with different stages of chronic kidney disease (CKD) (median age 9.2 years, range 3 months to 17.5 years) was determined using the iohexol plasma clearance, with blood sampling at seven time points within 5 h (GFR7p) as the reference method. Median GFR7p was 65.9 (range 6.3–153) mL/min/1.73 m2.

An accurate determination of iohexol clearance can be obtained from a single plasma sample applying the mean sojourn time approach. A separate formula  Iohexol- och Cr-EDTA-clearance ger både absolut och kroppsytenormerad njurfunktion. Skattning av eGFR med p-kreatinin eller cystatin? Bestämningen har tidigare vanligen skett genom mätning av endogent Kreatininclearance eller Cr-EDTA-clearance.

Skattning av eGFR med p-kreatinin eller cystatin? Eftersom det är tids- och resurskrävande att bestämma iohexolclearance, är läkare i många fall hänvisade till cystatin C eller kreatinin för beräkning av eGFR. GFR kan mätas som renalt clearance av inulin (”gold standard”), plasmaclearance av 51 Cr-EDTA eller plasmaclearance av iohexol. Eftersom dessa metoder är relativt dyra, komplicerade och innebär viss risk för patienter, används i praktiken oftast en skattning av GFR med hjälp av formler baserad på S-Cystatin C eller S-Kreatinin (estimerat GFR, eGFR).

23 A single dose of iohexol (Omnipaque™ 300) was administered at 300 mg iodine/kg Cr-EDTA, Inulin, Iohexol (Omnipaque) renalt clearance av sådan markör = GFR Ex: Cl Iohexol = (U Iohexol x Urinvolym)/ P Iohexol Cl Iohexol = GFR. 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.

Andra läkemedel får INTE injiceras i samma PVK som provtagning för iohexol sker. Renalt clearance och plasmaclearance för Iohexol stämmer väl överens, 

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. All use versions of the HPLC technique. Evaluation of the program shows that the method has a satisfactory performance.

Of interest, differences between plasma clearance of iohexol and urinary clearance of inulin were smaller, likely due to extrarenal elimination of iohexol. Strengths 

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 ].
