… 2004-02-01 AIMS: To investigate the agreement of glomerular filtration rate (GFR) determination between 51Cr-ethylenediaminetetraacetic acid (51Cr-EDTA) plasma clearance (GFREDTA) and 99mTc-diethylenetriaminepentaacetic acid (99mTc-DTPA) plasma clearance (GFRDTPA), the Gates 99mTc-DTPA renographic method (GFRGates) and the serum creatinine Chronic Kidney Disease Epidemiology … 51 Cr‐EDTA clearance was measured with the standard bolus injection technique and glomerular filtration rate (GFR) was calculated by the single‐sample method described by Jacobsson. Mannitol, 0·25 g kg −1 body weight (150 mg ml −1 ), was infused for 4–14 min and blood samples taken at 1‐, 2‐, 3‐ and 4‐h ( n = 24) or 2‐, 3‐, 3·5‐ and 4‐h after infusion ( n = 17). Plasma clearance of 51 Cr‐EDTA (51 Cr‐EDTA‐Cl) was described in 1967 by Garnett et al. as an alternative method to measure GFR and has been used in clinical nephrology since then. In spite of its use for almost four decades, studies comparing In‐Cl and 51 Cr‐EDTA‐Cl have either not included renal transplant recipients [ 12 - 22 ] in their population study or included only a few [ 23 ]. 2013-06-15 2010-08-01 The calculation of 51 Cr‐EDTA clearance by method II (Cl II) was based on a close relation between 51 Cr‐EDTA clearance and the reciprocal apparent volume of distribution normalized with respect to body surface area.

From a large database of 51Cr-ethylenediaminetetraacetic acid (51Cr-EDTA) renal clearance determinations using the two blood sample method, 598 patients, aged 1 week to 90 years, were selected. The results of the 51Cr-EDTA slope intercept clearance of the two blood sample method were used as reference.

In this study the correlation between a 2BS and the reference method (r ¼ 0.98) was also higher compared to the SBS method (r ¼ 0.94).Concerning 51 Cr-EDTA, the SBS method established in a previous study the correlation of the 2BS method with the reference multiple sample method is slightly higher when using a two-sample protocol (r 2 ¼ 0 Renal and plasma clearance of 51Cr-EDTA and plasma clearance of iohexol were sufficiently accurate to measure GFR (moderately strong evidence). Renal clearance of DTPA, renal clearance of iohexol, and plasma clearance of inulin had sufficient accuracy (limited evidence).

The aim of the present study was to compare the most commonly used GFR markers for clearance measurements, 51Cr-EDTA and iohexol, using two different methods for iohexol analysis, HPLC and X-ray fluorescence, referring both Clearance of iohexol, 51Cr-EDTA and endogenous creatinine for determination of glomerular filtration rate in pigs with reduced renal function: a comparison between different clearance techniques. Research output: Contribution to journal › Article A method is described whereby the plasma clearance of 51Cr‐EDTA is used to estimate the glomerular filtration rate (GFR) in conscious rats. EDTA clearance rates were calculated based on one and two exponential disappearance curves and compared in groups of animals studied under conditions of normal, high and low GFR. The precision of two different clearance methods as used for routine assessment of the glomerular filtration rate (GFR) was investigated in thirty-one children aged 0.6–14 years: total [51 Cr]EDTA plasma clearance (E) determined by a simplified single injection method; and 24 h endogenous creatinine clearance (C).

There were no significant differences between the renal clearances (Clren adv) of iohexol and 51Cr-EDTA or between their plasma clearances (ClAUC-3comp). 1998-05-01 2006-07-25 Iohexol and 51Cr-EDTA are comparable as GFR markers for multiple-point clearance measurements. The single-sample method for GFR >40 ml/min can be used with a high accuracy. The precision and accuracy of X-ray fluorescence analysis of low concentrations of iohexol were less than those of HPLC.
