An o-toluidine method for body-fluid glucose determination.
Featured Article: Dubowski KM. An o-toluidine method for body fluid glucose determination. Clin Chem 1962; 8:215–35. This report described a simple, rapid, and versatile method for manual measurement of glucose in whole blood, serum, cerebrospinal fluid (CSF), and other body fluids, with results fully compatible with the then–widely used automated Hoffman procedure for body-fluid glucose: reduc...
متن کاملAn enzymatic method for glucose determination in body fluids.
ENZYMATIC REACTIONS, BECAUSE of their great specificity, are among the most valuable analytic tools at the disposal of the chemist. The method for glucose here described represents an adaptation of such biologic reagents and is a distinct departure from sugar methods now in common use. It is based upon a unique principle communicated to us by Keston (1) prior to publication (2). Traditional met...
متن کاملFormaldehyde interference with the o-toluidine procedure for glucose.
We recently noticed a significant error in the results for glucose determined by the o-toluidine method in qualitycontrol material prepared in our own laboratory. This interference was traced to one component of this control material, a uric acid stock solution containing formaldehyde. Uric acid has been reported to interfere (1, 2) and not interfere (3) in the o-toluidine procedure. The otolui...
متن کاملAutomated determination of glucose in serum or plasma by a direct o-toluidine procedure.
A LDOHEXOSES REACT WITH o-toluidine in the presence of glacial acetic acid to produce a green color, which follows Beer’s law over a wide range of concentrations. This reaction is relatively selective for glucose. An improvement in manual procedures involving this reaction (1, 2) was reported by Feteris (3), who determined glucose directly on serum without deproteiization. She also improved the...
متن کاملMagnetic Multi-Walled Carbon Nanotube as an Adsorbent for Toluidine Blue O Removal from Aqueous Solution
Toluidine Blue O (TBO) is a cationic dye which is extensively used in the industries. In the present paper a simple and efficient wet chemical method was introduced for removal of TBO from waste aqueous solution. Magnetic multi-walled carbon nanotubes were synthesized using commercially available multi-wall carbon nanotubes and magnetic iron oxide nanoparticles which were examined for removal o...
