A new instrument, Eyetone, has been produced for use with a Dextrostix reagent strip for estimating blood sugar levels. It differs from the Dextrostix Reflectance Meter in having only one meter scale, a two-point calibration, and a range of measurement limited to 10-400 mg/100 ml. Results with the manufacturers' original calibration were unsatisfactory, but when recalibrated the performance of the instrument gave a regression equation line close to the ideal. The three Eyetone instruments tested were comparable in their accuracy and functional stability. Packed cell volumes in the blood samples in the range of 30-50% had a negligible effect on the results. The Dextrostix-Eyetone method represents a quick and reliable alternative to conventional laboratory methods for blood sugar estimation. It is especially useful for patients outside hospital.
一种名为“眼通仪(Eyetone)”的新仪器已生产出来,用于搭配葡萄糖试纸条估算血糖水平。它与葡萄糖反射仪的不同之处在于,只有一个仪表刻度、两点校准,且测量范围限于10 - 400毫克/100毫升。使用制造商原始校准的结果并不理想,但重新校准后,该仪器的性能给出了一条接近理想的回归方程线。所测试的三台眼通仪在准确性和功能稳定性方面相当。血样中血细胞压积在30%至50%范围内对结果的影响可忽略不计。葡萄糖试纸条 - 眼通仪法是传统实验室血糖估算方法的一种快速可靠的替代方法。它对院外患者特别有用。
