A simple, modified procedure for the Dextrostix-Eyetone system has been evaluated in order to enable the system to measure the concentration of glucose in serum as well as in whole blood. A reduction of the ordinary time of reaction on the Dextrostix from 60 to 45 sec gave serum glucose determinations by the Dextrostix-Eyetone system that correlated almost perfectly with those obtained by a specific conventional laboratory procedure. Thus, the coefficient of correlation was 0.99 and the regression line very close to the ideal line. As the modification is very simple and does not involve any changes in the adjustment of the instrument, it is recommendable in all cases where only serum samples are available.
为使Dextrostix-Eyetone系统能够测量血清和全血中的葡萄糖浓度,对该系统进行了一种简单的改良程序评估。将Dextrostix上常规反应时间从60秒缩短至45秒后,用Dextrostix-Eyetone系统测定血清葡萄糖,其结果与特定传统实验室方法所得结果几乎完全相关。因此,相关系数为0.99,回归线非常接近理想线。由于这种改良非常简单,且不涉及仪器调节的任何变化,所以在仅有血清样本的所有情况下都值得推荐。
