I believe we all have such experience. When we go to the hospital for physical examination, some blood test items need to be checked on an empty stomach. Why is this? Why does the blood test need to be done on an empty stomach? Next, let's have a look.
Why do blood tests need to be done on an empty stomach? What advantage does fasting blood test have?
Each kind of test method is different, the normal value is also different, and the data of the normal value is obtained through the determination of a large number of normal people's fasting blood. Because the body is relatively in the basic metabolic state when fasting, it can eliminate the influence of food and other factors, and the mood is relatively stable, so it can reflect the real situation of human blood and provide valuable proof for the diagnosis of diseases.

If the blood test after eating, after the food is digested, some components in the food will enter the blood, which will increase the concentration of some components in the blood, so the test results may not be accurate.
In the past, there are many items that need fasting blood test, but with the modernization of blood test technology, the way of testing blood has changed, so, such as liver function, renal function and other blood test items, have gradually not required fasting. Perhaps, with the development of medicine in the future, fasting blood test will become history.
