The price of blood glucose measurement is about 5-10 dollars. There are two ways to measure blood glucose in hospitals: one is to collect fingertip blood by finger prick method. The other is to use the method of venous blood collection to take external venous blood, and then use the instrument to test the blood glucose level, which is a more accurate and reliable method to measure the average level of blood glucose over the past 3 months. Postprandial blood glucose measurement is also possible, you can determine the blood glucose level 1-3 hours after the meal, in the case of fasting the blood glucose level will not exceed 6.1mmol / L, if the test exceeds 11.1mmol / L need to be taken seriously, because it has been considered to have diabetes.
