What are the precautions for measuring blood sugar? Please tell me about it.

There are many things to pay attention to when measuring blood sugar, including how to measure it several times a day, such as whether you can measure the blood sugar of two fingers for comparison and so on.

For diabetes, why should blood sugar be measured seven times a day?

Many sugar friends were asked to test their blood sugar seven times a day when they were just diagnosed, which was very puzzling. In fact, it is not necessary at first, and the blood sugar should be measured regularly 7 times according to the doctor's advice.

Because of Asian eating habits, it is usually three meals a day. To understand the blood sugar of diabetic patients before and after meals, it is necessary to measure blood sugar before and after meals, and then before going to bed at night, so there is a saying that "blood sugar is measured seven times a day".

Self-test refers to blood and other influencing items.

Generally speaking, there must be a difference between detecting peripheral blood (finger) and venous blood with a blood glucose meter. But the value found will not deviate too much. Clinically, it is difficult to have enough time to wait for the venous blood glucose value when rescuing patients, mainly because of the time limit.

There are many reasons that affect the accuracy of blood sugar data, such as whether the test paper absorbs moisture, whether the operator is skilled, whether the finger touches the surface of the test paper when measuring blood sugar, and the speed of reading data when measuring blood sugar will also affect the measured blood sugar value.

In addition, it is not recommended for diabetic patients to measure two fingers separately for blood sugar comparison. Diabetic patients have more or less some vascular diseases, especially peripheral blood. It is likely that the blood vessels in one finger are unobstructed and the blood vessels in the other finger are blocked. In this case, the detected blood sugar will be different. Therefore, the blood sugar values measured by different fingers of the same hand will be different.

If you don't want to compare blood sugar values, you can compare blood sugar tests under the same instrument, unified test paper, the same drop of blood and the same person.
