The Glucocard (Kyoto Daiichi Kagaku) blood glucose meter is designed for self-monitoring of blood glucose concentrations in capillary blood through use of an electrochemical test strip. Evaluated in this laboratory, the Glucocard had CVs of 4.6%, 6.6%, and 3.5% at blood glucose concentrations of 2.4, 4.1, and 18.9 mmol/L, respectively. The meter's response varied linearly with blood glucose concentration between 2.2 and 27.8 mmol/L. Hemolysis, urate, ascorbate, and acetaminophen interfered by > 5%. Different hematocrits, in the range 0.20-0.70, did not affect the measured glucose concentration. Comparison with glucose results measured in whole blood with a NOVA Stat Profile 5 instrument yielded the following: Glucocard = 0.898 NOVA--0.184 (r = 0.995). The main advantages of the Glucocard are its small sample volume (5 microL), wide linear range, and fully automated sample-handling steps, which reduce user-related variability.
京都第一化学株式会社的Glucocard血糖仪旨在通过使用电化学测试条对毛细血管血中的血糖浓度进行自我监测。在本实验室进行评估时，Glucocard血糖仪在血糖浓度分别为2.4、4.1和18.9 mmol/L时的变异系数（CV）分别为4.6%、6.6%和3.5%。该血糖仪在2.2至27.8 mmol/L的血糖浓度范围内，其响应与血糖浓度呈线性变化。溶血、尿酸盐、抗坏血酸盐和对乙酰氨基酚的干扰率>5%。不同的血细胞比容（范围为0.20 - 0.70）不会影响所测的葡萄糖浓度。与使用NOVA Stat Profile 5仪器在全血中测得的葡萄糖结果进行比较，结果如下：Glucocard = 0.898×NOVA - 0.184（r = 0.995）。Glucocard血糖仪的主要优点是样本量小（5微升）、线性范围宽以及样本处理步骤完全自动化，这减少了与用户相关的变异性。
