比较表精度

任何人谁一直试图控制他或她的糖尿病超过几天经常被与检查血糖水平感到失望了。我们失望的是，有时并不怎么高的水平去，但怎么我们的飘忽不定仪和试纸似乎是道德的。仪表精度是一种痛苦 - 的情绪上的痛苦，可以超过采血的身体上的痛苦。究竟是哪个仪表系统精度？这可能是问题的人初诊糖尿病患者问我最多的。而现在是第一次，我们有一个答案的开始。在我15年的糖尿病之后的发展我还没有看到的血糖仪一个科学的比较，我们必须与工作。到现在。而现在我们有来自各大品牌以及一些次要的比较米的研究。这项研究比较了27血糖监测系统包括四大美国市场，LifeScan公司，罗氏，拜耳，雅培和系统上。 These are the four companies that seem to have a lock on reimbursement from almost all medical insurance plans. Strangely, the study appears without fanfare. I only learned about it from an executive of i-SENS, the Korean meter manufacturer that invited me to visit South Korea last month. i-SENS makes blood glucose meters and test strips for many other companies that sell them under their own names, and I don't know which, if any, of the meter systems that the new study evaluated came from i-SENS.该研究发表在糖尿病技术与治疗的2010年2月发行的“27血糖的系统精度评估监测系统根据DIN EN ISO 15197.”更好的消息是，该杂志的出版商，玛丽安力博特公司，正在提供到到11世界糖尿病日，这是11月14日除了糖尿病技术与治疗学荣誉年底起其出版物的全文免费在线访问，这包括代谢综合征及相关疾病和儿童肥胖。您可以在查电表的精度研究全文http://www.liebertonline.com/doi/pdfplus/10.1089/dia.2009.0128。
乍一看，这项研究可能不会出现相关的美国人，因为按照欧洲标准评估系统。But the fact is that the U.S. Food and Drug Administration has de facto adopted those standards for the U.S. The European standards are that at least 95 percent of our blood glucose test results have to fall within plus or minus 15 mg/dl of the true result when the level is below 75 mg/dl. The standard allow a little more leeway at higher levels. Our test results have to fall within plus or minus 20 percent when the level is above 75 mg/dl. That's simply because test results at lower levels are critical -- particularly in terms of insulin dose -- so these standards make sense. The good news is that blood glucose systems from three of the four major meter manufacturers fulfilled the European requirements. Five meters from the big four fulfilled the requirements 100 percent. These are Roche's Accu-Chek Aviva and Accu-Chek Active, Abbott's FreeStyle Freedom and FreeStyle Lite, and LifeScan's One Touch Ultra2. Also scoring 100 percent were two meters from a smaller company, Bionime. In total, 16 of the 27 systems in the study fulfilled Europe's minimum accuracy requirements. That means, of course, that more than 40 percent of them simply aren't good enough. Quite a few of these meters are, however, not even sold in the U.S. We knew, of course, that our meters in general aren't good enough. And now we know which ones that we can tend to trust. Anyway, I do encourage you to read the system accuracy evaluation study. At a minimum, please note the tables on "BG Monitoring System Accuracy Results" and "Clarke Error Grid Analysis." Then, you may want to get a meter to replace the old one that you have been using.
