How to measure fasting blood glucose most accurately

There is generally no such thing as a "most standard" method for measuring fasting blood glucose. Fasting blood glucose measurement is helpful for evaluating glucose control and is primarily used for diabetes screening and management. To perform a standard fasting blood glucose measurement, follow these steps:

1. Ensure fasting duration: Before the fasting blood glucose test, ensure a fasting period of at least 8 hours but not exceeding 12 hours. This means no food or beverages (except water) should be consumed from after the previous evening's dinner until before breakfast the next day.

2. Avoid strenuous exercise: Avoid strenuous physical activity within 24 hours before the test, as exercise may affect blood glucose levels.

3. Stay relaxed: Emotional stress or anxiety can also affect blood glucose readings, so remain calm and relaxed before the measurement.

4. Pay attention to sampling time: The accurate time for fasting blood glucose sampling is typically in the morning before breakfast. It is recommended to perform the test between 8:00 AM and 10:00 AM, as blood glucose levels tend to be relatively stable during this period.

5. Proper use of the glucose meter: Operate the blood glucose meter correctly according to the manufacturer's instructions, including steps such as calibrating the device, inserting the test strip, collecting the blood sample, and reading the result.

6. Record the results: Promptly record the measured blood glucose value, along with the time of measurement and any factors that may have affected the glucose level, such as diet, exercise, or medications, to assist in subsequent analysis and adjustment of treatment plans.
