An o-Toluidine Method for Body-Fluid Glucose Determination

Abstract

Since publication of the above paper, we have found that a procedure similar to the one described for determination of aldosaccharides in body fluids using o-toluidine in glacial acetic acid solution was described by Eric Hultman in Nature183, 108 (1959). A modification of Hultman's procedure has recently been described by A. Hyvärinen and E. A. Nikkilä in Clin. Chim. Acta7, 140 (1962).The omission of reference to Dr. Hultman's paper was entirely unintentional. Our own procedure was, of course, derived entirely experimentally, based upon Dr. O. M. Forsell's suggestion to us of Mar. 13, 1960, that we should consider the use of o-toluidine as a glucose reagent; and this suggestion is properly credited in the paper as a personal communication. The papers by Hultman and by Hyvärinen and Nikkilä nicely confirm some of the significant experimental details and results of our procedure; but obviously the Hultman paper has priority with respect to this principle.
