Precautions:

1, fasting blood glucose test is the most important thing to pay attention to. Generally speaking, fasting blood glucose is mainly the blood glucose level 8 ~ 12 hours after fasting. Because fasting for a period of time, the blood sugar level will tend to be stable, and there will be no sudden fasting and sudden drop of blood sugar, so the obtained blood sugar level is more accurate.

2, the night before the blood sugar test must ensure adequate sleep and good sleep quality, because unhealthy sleep habits will affect the human environment, induce hormone secretion disorder, and lead to an increase in blood sugar levels.

3. Too excited or fluctuating emotions will affect the central nervous system of the human body and lead to an increase in blood sugar.
