What Preparations Are Needed for a Fasting Blood Glucose Test?

The day before a fasting blood glucose test, you need to ensure that you are in a true fasting state, avoid vigorous exercise, and pay attention to rest and other precautions.

1. Fasting State: Fasting means not eating after dinner on the day before the blood glucose test. No snacks, drinks, etc., are allowed during this period. You can eat normally during the day without excessive dieting to avoid affecting the blood glucose results. The fasting time should be 8 to 10 hours before the blood glucose test the next day.

2. Avoid vigorous exercise before a fasting blood glucose test. Vigorous exercise can increase adrenaline and insulin levels, causing a slight increase in blood glucose and affecting the accuracy of the test results. Avoid vigorous exercise.

3. If the patient experiences insomnia, stays up late, etc., on the day before the test, although they can maintain a fasting state, blood glucose fluctuations will still be affected to some extent, which will have a certain impact on the blood glucose test results. Therefore, patients should ensure sufficient rest and avoid excessive fatigue before the test.
