For people with diabetes, self-monitoring of blood glucose is of great importance. By monitoring the change of blood glucose, we can keep abreast of the control of blood glucose and reduce the harm of diabetes and its complications. Clinically, we often encounter some patients with bias in the understanding of blood glucose testing. How to measure blood glucose? 1. First of all, blood glucose monitoring should be chosen at a suitable time. Diabetic patients need to monitor blood glucose before and after three meals and at bedtime, that is, seven times a day, specifically, the clinic mostly uses two indicators: fasting blood glucose refers to overnight fasting for more than 8 hours, and the blood glucose value taken before breakfast, which is the true meaning of basic blood glucose; 2 hours after meal blood glucose refers to the blood glucose value of breakfast, lunch and dinner for 2 hours from the first bite, not 2 hours after eating. This point should be noted in particular, the bedtime blood glucose generally refers to the value measured before going to bed at night (about 21:00 —-22:00). 2. Secondly, the frequency of blood glucose monitoring. The frequency of blood glucose monitoring should be decided under the guidance of a specialist and after comprehensive consideration of blood glucose level and current treatment plan. Generally speaking, if you are a newly diagnosed patient or have just recently adjusted your treatment plan or have recent blood glucose fluctuations or other conditions (such as surgery, alcohol consumption, trauma, etc.), you should increase the frequency of blood glucose monitoring, 4-7 times a day. If the blood glucose is often low recently, you should monitor the pre-meal blood glucose and night blood glucose (usually take the test at 1:00 am and 3:00 am). Now many diabetic patients have bought fast blood glucose meter, the following and you talk about the method and steps of blood glucose test: 1, disinfect your fingers with alcohol and dry them, rotate your fingers, try not to use your toes 2, install the test paper correctly, check the test paper type 3, pen blood collection needle to collect blood 4, to flow out a drop of blood, drop in (suck in) the corresponding part of the test paper 5, wait for the result 6, read the value, and make a record .
