How to test your blood sugar accurately in an empty stomach? 



What do diabetics need to know when to monitor their blood sugar on an empty stomach? Diabetes: How does glucose meters work? This article will help you test blood sugar with Blood Glucose meters?

1. The time on an empty stomach to reach 8 hours

Many people with diabetes think they don't eat when they get up in the morning, and the result of blood sugar monitoring is fasting blood sugar, but that's not the case, diabetics need to fast for eight hours to get the right fasting blood sugar before they can count as fasting blood sugar.

2. Blood sugar needs to be monitored between 6:00 a.m. and 8:00 a.m

Many people with diabetes think that getting up in the morning and not eating for blood sugar monitoring is what they want fasting blood sugar, but most people do not know that the best time to measure fasting blood sugar is 6:00 a.m. to 8:00 a.m., not too early and not too late, so diabetics should adjust the time to eat the night before according to the time to measure blood sugar in the morning.

3. To ensure that sleep is normal:

Some people with diabetes have the habit of often staying up late, and staying up late will make their sleep quality lower, will let oneself appear sleep deprivation phenomenon, and sleep easy to have a certain impact on blood sugar, when sleep is insufficient or sleep quality is not good will lead to the 2nd sky abdominal blood sugar blood sugar value also followed by errors.

4. Get up to take sugar-lowering drugs

Some diabetics wake up afraid of their blood sugar rise, take drugs and then blood sugar monitoring, but do not know that after taking drugs the drug will quickly play a drug effect to let blood sugar drop, so that fasting blood sugar monitoring can not get accurate results, so diabetics need to have an empty stomach blood sugar test, be sure to check before using the drug.

5. To choose to exercise in the morning before the air-abdominal blood sugar monitoring

Some diabetics get up in the morning have the habit of morning exercise, so some patients need to get up on an empty stomach because the time is relatively early, think that they are in the morning exercise after blood sugar monitoring is also available, but do not know that morning exercise will let their body's blood sugar drop, so after morning exercise blood sugar monitoring will be the wrong blood sugar results, so be sure to do before morning exercises before the blood sugar monitoring.

Warmer Notice: For fasting blood sugar check diabetics to understand these points, so that they can check their own time will not make mistakes, to prevent some wrong behavior to allow their measured fasting blood sugar values are not accurate.

FAQ - Blood Glucose Monitoring:

Blood glucose levels often change over time. And it will vary depending on where the blood sample was taken.

Difference in measurement time

Even after the patient has just returned home from the hospital to check his blood sugar, he will find that the blood glucose level measured at home is different from the blood glucose level measured in the hospital. The reason is that with the physical activity, the body must consume blood sugar. After eating, the ingested blood sugar will enter the blood to supplement the consumed blood sugar.

Different sampling points

It is supplied from the heart to the capillaries through the arteries. After the blood supplies nutrients including blood sugar to various tissues of the body, it returns to the heart through the veins. When the blood glucose test strip is used for testing, the sampling site used is the capillaries of the fingers. The capillary blood contains part of the blood whose blood sugar has been exhausted.

Therefore, the blood glucose level measured with a blood sample from the arm in the hospital will be different from the blood glucose level measured with a blood sample from the fingertip.

Will blood sugar levels change due to different measurement methods?

Yes, it will be different. In the following cases, different measurement methods will affect the measurement results (incorrect results appear).

  1. During the blood suction process, if the blood glucose test strip is removed from the blood before the beep sounds, the measurement result will be affected.
  2. During the blood suction process, if the blood glucose test strip is kept in contact with the blood for a long time after the "di" sound, the measurement result will also be affected.

Measurements are taken after a period of time after the blood is drawn

Once in contact with air, the blood will immediately begin to clot. And after the blood clotting phenomenon develops to a more significant degree. It is impossible to obtain correct measurement results.

Therefore, it is necessary to start drawing blood immediately after the amount of blood reaches a sufficient level. If you need to repeat the measurement, wipe off the blood at the puncture point, start from the beginning, and measure again.

The blood has been sucked, and the blood has been sucked again.

During the blood suction process. If the blood glucose test strip is removed from the blood and the blood is drawn again, the correct measurement result cannot be obtained in this case. Therefore, a new blood glucose test strip should be replaced, and after the blood volume has reached a sufficient level, the measurement should be performed again (do not remove the blood glucose test strip from the blood during the blood aspiration process).

Excessive force when squeezing blood leads to inaccurate blood glucose testing.

If you apply too much force when squeezing, the transparent intracellular fluid in the subcutaneous tissue will also be squeezed out and mixed with the blood. This may lead to incorrect measurement results.

The blood glucose test strip is left in the air for too long, and the blood glucose test strip penetrates the moisture in the air, which will affect the measurement result.
