The ExacTech system, a new device for home measurement of blood glucose was tested in the laboratory, in the out-patient clinic, and by diabetic patients. The system is based on an electrochemical principle, and consists of specially impregnated strips and a small, pencil-shaped meter. (1) Six meters were tested in the laboratory at blood glucose concentrations of 4, 10 and 20 mmol/l. Low coefficients of variation were found at 10 and 20 mmol/l, but those at 4 mmol/l were rather high (approximately 10%). Analysis of variances showed no difference in the between and the within variation of the meters. (2) The blood glucose concentrations of 50 consecutive out-patients were determined by the ExacTech system and a standard laboratory method. Correlation analysis showed an r value of 0.95 (P less than 0.001). (3) The results obtained by 13 patients repeating the correlation experiment were in agreement with the second part of the study. The ExacTech system is very simple to operate by the patients, and can be recommended for home monitoring of blood glucose.
ExacTech系统是一种用于家庭血糖测量的新设备，已在实验室、门诊以及糖尿病患者中进行了测试。该系统基于电化学原理，由经过特殊浸渍的试纸条和一个小型铅笔状血糖仪组成。（1）在实验室中，于血糖浓度为4、10和20毫摩尔/升的情况下对六台血糖仪进行了测试。在10和20毫摩尔/升时变异系数较低，但在4毫摩尔/升时变异系数相当高（约10%）。方差分析表明各血糖仪之间和内部的变异无差异。（2）采用ExacTech系统和标准实验室方法对50名连续门诊患者的血糖浓度进行了测定。相关分析显示r值为0.95（P小于0.001）。（3）13名患者重复进行相关实验所得到的结果与该研究的第二部分一致。ExacTech系统患者操作非常简便，可推荐用于家庭血糖监测。
