目的：本研究比较了四种增值血糖仪的准确性和精密度。方法：使用雅培糖尿病护理(Alameda，CA)Optium(TM)、诊断设备公司(迈阿密，佛罗里达州)DDI Prodigy(R)、Home Diagnostics，Inc.(佛罗里达州劳德代尔堡)HDI True Track Smart System(R)和美国Arkray(明尼阿波利斯，明尼阿波利斯)HypoGuard Assue(R)Pro对糖尿病患者进行手指棒状血糖测量。手指血糖测量结果与实验室参考结果进行了比较。准确度通过Clarke误差网格分析(EGA)、Parkes EGA以及实验室价值标准(CHI(2)分析)的5%、10%、15%和20%进行评估。结果：共获得125例糖尿病患者的手指，其中高加索人占90.4%，女性占51.2%，2型糖尿病患者占83.2%，平均年龄59岁(SD14岁)。平均血糖151 mg/dL(SD+/-65 mg/dL；范围58~474 mg/dL)。Clarke EGA在94%的Optium、82%的Prodigy、61%的True Track和77%的Assue Pro样本中证明了临床准确性(与所有其他样本相比，Optium和True Track的P<；0.05)。根据Parkes EGA，True True赛道的精确度明显低于其他米。在5%以内的准确率分别为34%、24%、29%和13%(与True Track相比，Optium、Prodigy和Assue Pro的P<；0.05)。与True Track相比，Optium、Prodigy和Assue Pro的准确率在10%以内要高得多。与其他仪表系统相比，Optium结果在15%和20%的精确度内表现出更大的优势。结论：雅培公司的精确度明显高于其他计量器系统，而HDI True True计量器的精确度明显低于其他计量器系统。
Purpose: This study compared the accuracy and precision of four value-added glucose meters.Methods: Finger stick glucose measurements in diabetes patients were performed using the Abbott Diabetes Care (Alameda, CA) Optium (TM), Diagnostic Devices, Inc. (Miami, FL) DDI Prodigy (R), Home Diagnostics, Inc. (Fort Lauderdale, FL) HDI True Track Smart System (R), and Arkray, USA (Minneapolis, MN) HypoGuard Assure (R) Pro. Finger glucose measurements were compared with laboratory reference results. Accuracy was assessed by a Clarke error grid analysis (EGA), a Parkes EGA, and within 5%, 10%, 15%, and 20% of the laboratory value criteria (chi(2) analysis). Meter precision was determined by calculating absolute mean differences in glucose values between duplicate samples (Kruskal-Wallis test).Results: Finger sticks were obtained from 125 diabetes patients, of which 90.4% were Caucasian, 51.2% were female, 83.2% had type 2 diabetes, and average age of 59 years (SD 14 years). Mean venipuncture blood glucose was 151 mg/dL (SD +/- 65 mg/dL; range, 58-474 mg/dL). Clinical accuracy by Clarke EGA was demonstrated in 94% of Optium, 82% of Prodigy, 61% of True Track, and 77% of the Assure Pro samples (P < 0.05 for Optium and True Track compared to all others). By Parkes EGA, the True Track was significantly less accurate than the other meters. Within 5% accuracy was achieved in 34%, 24%, 29%, and 13%, respectively (P < 0.05 for Optium, Prodigy, and Assure Pro compared to True Track). Within 10% accuracy was significantly greater for the Optium, Prodigy, and Assure Pro compared to True Track. Significantly more Optium results demonstrated within 15% and 20% accuracy compared to the other meter systems. The HDI True Track was significantly less precise than the other meter systems.Conclusions: The Abbott Optium was significantly more accurate than the other meter systems, whereas the HDI True Track was significantly less accurate and less precise compared to the other meter systems.
