What to pay attention to before blood sugar test

Blood sugar testing is very necessary, whether it is to understand the health status of the body or to treat certain diseases. Conducting necessary blood sugar testing is beneficial for symptomatic medication and for health care in life. If you want to know your blood sugar level, you often need to do a blood sugar test. Since our body's blood sugar is affected by many factors, in order to maximize the accuracy of the test, many issues must be paid attention to before and after the blood sugar test.

Some blood glucose meters require you to adjust the code displayed on the meter before testing to make it consistent with the code on the test strip box. After the blood collection site is disinfected with alcohol, blood collection must continue after the alcohol evaporates to avoid a chemical reaction between the alcohol and the substance on the test strip, which would result in inaccurate blood sugar test values. The amount of blood collected must be able to completely cover the entire testing area of ​​the test strip. Insufficient blood volume will lead to test failure or low measured value; if too much blood overflows the test area, it will not only contaminate the instrument but also cause errors in the test results. Check as soon as possible to ensure the quality of blood glucose testing. Insert the blood test strip completely into the bottom of the test hole.

Generally speaking, for patients who need to do a fasting blood sugar test, the doctor will tell you not to eat in the morning when having your blood drawn. As for what time to have your blood drawn, how long you should fast for, or whether you can drink water, sometimes there is no special emphasis. When some people hear that they need to check their fasting blood sugar, they go to the test without eating breakfast or drinking water that morning. Generally speaking, drinking boiled water will not interfere with the blood sugar monitoring results. The "fasting" required for fasting blood glucose monitoring generally refers to no calorie intake, such as eating staple foods, meat, eggs, milk and other foods, without strictly restricting drinking water. So you can eliminate your concerns and drink a small amount of water if you are thirsty before measuring your fasting blood sugar. However, some sugary drinks should be limited as they may affect the results of blood sugar tests.

This is an introduction to the precautions for blood sugar testing. It should be emphasized here that many diabetic patients have high blood sugar levels. It is best for such patients to have a blood sugar test once a month, which can help them judge their blood sugar levels well and provide a reliable basis for the dosage of insulin.
