The objective of our study was to assess the influence of hematocrit (HCT), partial pressure of oxygen (PO2), and blood glucose level upon results obtained with three different blood glucose reagent strip tests used in conjunction with the appropriate meter: BM-Test 1-44, BM-Accutest, and Satellite G.
Our study was designed as a consecutive sample study of patients undergoing coronary artery surgery. The setting was the hospital theater and intensive care unit. We conducted blood analysis for HCT, PO2 and blood glucose on 20 consecutive patients undergoing coronary artery surgery using three blood glucose reagent strip testing systems and a laboratory analysis of plasma glucose.
All three blood glucose reagent strip tests showed a significant bias when compared with plasma glucose: BM-Test 1-44, 0.89 mmol/L; BM-Accutest, -1.27 mmol/L; Satellite G, 0.75 mmol/L (p < 0.05). The error found when using the Satellite G system was worse than that of either of the other two systems. Results obtained with the BM-Accutest strips were unaffected by PO2 (p = 0.745). Blood glucose value and HCT both had an influence on the results of all three blood glucose strip systems.
Caution must be taken when using reagent strip systems in the operating room or intensive care setting because, of the three systems tested, all showed a significant bias, all were influenced by blood glucose level and HCT, and only the BM-Accutest reagent strips used with the Accutrend meter was unaffected by PO2.
我们研究的目的是评估血细胞比容（HCT）、氧分压（PO2）和血糖水平对三种不同血糖仪配套使用的血糖试纸测试结果的影响：BM-Test 1-44、BM-Accutest和Satellite G。
我们的研究设计为对接受冠状动脉手术的患者进行连续样本研究。研究地点为医院手术室和重症监护病房。我们使用三种血糖试纸测试系统对20例连续接受冠状动脉手术的患者进行了HCT、PO2和血糖的血液分析，并对血浆葡萄糖进行了实验室分析。
与血浆葡萄糖相比，所有三种血糖试纸测试均显示出显著偏差：BM-Test 1-44为0.89 mmol/L；BM-Accutest为-1.27 mmol/L；Satellite G为0.75 mmol/L（p < 0.05）。使用Satellite G系统时发现的误差比其他两个系统中的任何一个都要大。BM-Accutest试纸的结果不受PO2的影响（p = 0.745）。血糖值和HCT均对所有三种血糖试纸系统的结果有影响。
在手术室或重症监护环境中使用试纸系统时必须谨慎，因为在所测试的三种系统中，所有系统均显示出显著偏差，均受血糖水平和HCT的影响，并且只有与Accutrend血糖仪配套使用的BM-Accutest试纸不受PO2的影响。
