To determine the reliability of seven different alternative glucose test strips manufactured for use with three different glucose meters.
Venous blood samples were obtained from volunteers to test trade name glucose test strips on the manufacturers' glucose meters (One Touch II, Glucometer II, and Glucometer III), and the remainder of each sample was used for laboratory determination of blood glucose levels. In addition to the trade name test strips, Quick Check and First Choice test strips were tested on all meters, and Biotel test strips were also tested on the Glucometer III.
In linear regression analysis, the R2 ranged from 0.84 to 0.97 for the test strips compared with plasma glucose values. The test strips with the highest accuracy and precision at all ranges of blood glucose levels were the One Touch II and Glucometer III trade name strips and the Quick Check and First Choice alternative strips for the One Touch II glucose meter and the First Choice alternative strip for the Glucometer II. Subgroup analysis based on ranges of blood glucose values, however, revealed that the alternative strips were not as accurate as the trade name test strips, with the exception of the First Choice alternative test strip for the Glucometer II. All of the trade name test strips were more precise than the alternative test strips designed for the individual meters.
Alternative glucose test strips can be used to predict the actual laboratory blood glucose values but are generally not as accurate or precise as the trade name test strips.
确定为与三种不同血糖仪配套使用而生产的七种不同的替代血糖测试条的可靠性。
从志愿者身上采集静脉血样本，以在制造商的血糖仪（One Touch II、Glucometer II和Glucometer III）上测试商品名血糖测试条，每个样本的其余部分用于实验室测定血糖水平。除了商品名测试条外，还在所有血糖仪上测试了Quick Check和First Choice测试条，并且在Glucometer III上也测试了Biotel测试条。
在线性回归分析中，与血浆葡萄糖值相比，测试条的R2范围为0.84至0.97。在所有血糖水平范围内具有最高准确度和精密度的测试条是One Touch II和Glucometer III商品名测试条以及One Touch II血糖仪的Quick Check和First Choice替代测试条以及Glucometer II的First Choice替代测试条。然而，基于血糖值范围的亚组分析显示，除了Glucometer II的First Choice替代测试条外，替代测试条不如商品名测试条准确。所有商品名测试条都比为个别血糖仪设计的替代测试条更精密。
替代血糖测试条可用于预测实际实验室血糖值，但通常不如商品名测试条准确或精密。
