及时准确的POCT血糖检测,是住院患者血糖管理的基础。与个人自我血糖监测不同,由于住院病人情况的复杂性,院内POCT血糖监测不仅使用毛细血管血、还会用到动脉血、静脉血或新生儿血。作为POCT血糖监测过程中最重要的组成部分,为病人选择正确类型的血样和合适的血糖仪进行检测,决定着最终检测结果的准确性和临床相关性。在人体正常状态下,由于体内血液会顺畅的循环流动,使得动脉、静脉和毛细血管中的血液成分保持相对的一致性,此时我们选用毛细血管血来检测血糖,就可以相对真实的反映体内的血糖水平,而且采集方便、创伤小。因此毛细血管血比较适用于个人患者在家庭环境下进行自我血糖监测时使用。目前市售的所有便携式血糖仪都可以用来检测毛细血管血。但是临床上有很多疾病状态会对血液循环产生显著 Timely and accurate detection of POCT blood glucose, blood glucose management in hospital patients based. Different from self-blood glucose monitoring, due to the complexity of hospitalized patients, POCT blood glucose monitoring in the hospital not only uses capillaries, but also arterial blood, venous blood or neonatal blood. As the most important part of the POCT blood glucose monitoring process, the right type of blood sample and the right blood glucose meter are selected for the patient to determine the accuracy and clinical relevance of the final test result. In the normal state of human body, due to the smooth circulation of blood in the body, the blood components in arteries, veins and capillaries are relatively consistent. At this time, we use capillary blood to detect blood glucose, which can relatively reflect the body in vivo Blood sugar level, but also easy to collect, less trauma. Therefore, capillary blood is more suitable for personal use of self-monitoring of blood glucose in a home environment. All portable blood glucose meters currently available on the market can be used to detect capillary blood. However, there are many clinical conditions that can cause significant blood circulation
