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. Comparison of studies reporting renal clearance measurements using iohexol versus

Clearance of iohexol, chromium-51-ethylenediaminetetraacetic acid, and creatinine for determining the glomerular filtration rate in pigs with normal renal function: comparison of different clearance techniques Ioheksol-clearance er et mål for hvor mye av blodets plasma som renses for ioheksol i løpet av en viss tid. Clearance angis i milliliter per minutt, og brukes for å bestemme den glomerulær filtrasjonsraten (GFR), som er et mål på nyrefunksjonen.Ioheksol er et kontrastmiddel som vanligvis brukes ved røntgenundersøkelse. 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. Iohexol is an X-ray contrast medium containing iohexol in various concentrations, from 140 to 350 milligrams of iodine per milliliter.

Measurement of Peripheral Pressures eGFR är baserad på samband mellan P/S-Kreatinin och (iohexol) clearance i en population och är därför inte individrelaterad. Individens Flerpunkts-clearance görs när patienten har ovanliga ”kroppsproportioner” eftersom uträkning av fördelningsvolym av Iohexol inte behövs. För patienter med GFR determination in adults with a single-sample iohexol plasma clearance method based on the mean sojourn time.

Iohexol total clearance was identical to 51Cr-EDTA, whereas urinary clearance of iohexol was slightly higher. Finally, they showed that iohexol was distributed within the extracellular volume [22]. This iohexol distribution pattern applies also to patients with CKD and obese subjects [22–26]. Importantly for a GFR marker, other studies

Iohexol clearance for GFR-determination in renal failure - single or multiple plasma sampling? Nephrology, dialysis, transplantation : official publication of the European Dialysis and Transplant Association - European Renal Association , 11 (3), 521-525.

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.

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. Platinum clearance had a significant linear relationship to GFR (99mTc-DTPA) (CL (PT) = 2.5 x GFR (99mTc-DTPA)) and to GFR (Iohexol) (CL (PT) = [1.3 x GFR (Iohexol)] + 1.4). Iohexol Clearance in Critically Ill Patients With Augmented Renal Creatinine Clearance (GFR-ARC) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators.
