Reproducibility of GFR measured by chromium-51-EDTA and iohexol.
We read with interest the article published by Bird et al about the reproducibility of measured GFR by iohexol and Cr-51-EDTA [ 1 ]. We would like to make one comment and to share our own results on this fundamental (although understudied) topic. As we already pointed out in a NDT editorial, we share the same reserves about the opportunity to index glomerular filtration rate (GFR) with body sur...
متن کاملReproducibilities and responses to food intake of GFR measured with chromium-51-EDTA and iohexol simultaneously and independently in normal subjects.
BACKGROUND The aim was to evaluate the reproducibility of glomerular filtration rate (GFR) measured with iohexol and its response to food in a direct and independent comparison with Cr-51-ethylenediaminetetraacetic acid (EDTA), and examine the influence of two different whole body scaling parameters, body surface area (BSA) and extracellular fluid volume (ECV). METHODS Fasting and non-fasting...
متن کاملGFR measurement with iohexol and 51Cr-EDTA. A comparison of the two favoured GFR markers in Europe.
BACKGROUND 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 to the multiple-sample and single-sample calculations, using 51Cr-EDTA as the reference method. METHODS Forty-nine patients with an estimated GFR >40 ml/min wer...
متن کاملMeasured GFR as a confirmatory test for estimated GFR.
Clinical assessment of kidney function is central to the practice of medicine. GFR is widely accepted as the best index of kidney function in health and disease, and accurate values are required for optimal decision making. Estimated GFR based on serum creatinine is now widely reported by clinical laboratories, and in most circumstances, estimated GFR is sufficient for clinical decision making....
متن کاملCorrection factors after having neglected the first exponential in the estimation of chromium-51 EDTA clearance: a reappraisal.
The aim of the present work was to evaluate two classical formulae allowing the correction for having neglected the first exponential in the slope-intercept method used for the determination of EDTA clearance, namely the Chantler's linear correction formula (CH) and the Bröchner-Mortensen's quadratic correction formula (BM). First, a comparison study was performed with the two correction formul...
