Evaluation of an improved Reagent Strip system for measuring blood glucose.

Using a new, synthetic whole-blood control and an improved reflectance meter, the within-run precision of Dextrostix Reagent Strips for quantitative determination of blood-glucose levels is compared with three common manual methods (hexokinase, o-toluidine, and glucose oxidase), and one automated method (neocuproine-AutoAnalyzer). In addition, the strip is compared on a day-to-day basis with the o-toluidine method. Dextrostix, used with the new instrument and control, provides results that compare very well with the other methods for within-run precision, and with the o-toluidine method for day-to-day results.
