    • A system for measuring a glucose level in a blood sample includes a test strip (10) and a meter. The test strip (10) includes a sample chamber, a working electrode (22), a counter electrode (24), fill-detect electrodes (28, 30), and an auto-on conductor (48). A reagent layer is disposed in the sample chamber. The auto-on conductor (48) causes the meter to wake up and perform a test strip sequence when the test strip (10) is inserted in the meter. The meter uses the working and counter electrodes (22, 24) to initially detect the blood sample in the sample chamber and uses the fill-detect electrodes (28, 30) to check that the blood sample has mixed with the reagent layer. The meter applies an assay voltage between the working and counter electrodes (22, 24) and measures the resulting current. The meter calculates the glucose level based on the measured current and calibration data saved in memory from a removable data storage device associated with the test strip (10).
    • 用于测量血液样品中的葡萄糖水平的系统包括测试条(10)和计量器。 测试条(10)包括样品室,工作电极(22),对电极(24),填充检测电极(28,30)和自动导体(48)。 试剂层设置在样品室中。 当测试条(10)插入仪表中时,自动导体(48)使仪表醒来并执行测试条序列。 仪器使用工作电极和对电极(22,24)来初始检测样品室中的血液样品,并使用填充检测电极(28,30)来检查血液样品是否与试剂层混合。 仪表在工作电极和对置电极(22,24)之间施加测定电压,并测量所得到的电流。 仪器根据与测试条(10)相关联的可移动数据存储设备中保存在存储器中的测量电流和校准数据来计算葡萄糖水平。
