Blood tests are better in the morning.

Morning on an empty stomach. Generally speaking, most of the so-called tests that require fasting blood are biochemical tests. For example, the liver.

Function, blood sugar, protein, lipids, electrolytes potassium, sodium, chloride, etc. Biochemical tests are performed using quantitative methods.

The biochemical components of the blood are determined to understand their trace changes and to make a diagnosis accordingly and**. Biochemical tests.

All normal values are obtained by statistical processing based on the values measured in the fasting blood of normal people.

All of the test results are within a normal range.

Fasting blood refers to venous blood drawn in the morning before eating, and various biochemical components are relatively stable. measured.

The values can reflect the biochemical changes of the body more realistically. If blood is taken after eating, in the blood.

There will be temporary changes in biochemical composition, and the measured results do not reflect the real condition of the body, and cannot be compared.

Fasting blood is measured with normal values, so that accurate clinical judgments cannot be made.

However, if virological testing is performed, fasting blood is not required.

Heart rate varies widely, and may be related to the environment you measure, your physical condition on the day, and your mood. However, the normal heartbeat is 60 to 80 beats per minute, so this is within the normal range, so don't worry.

Before the blood test, fasting time is generally 8 hours for staple food, and 4 hours of fasting for water, drinks and other liquids to reach the standard, so it is best not to eat anything or water after 9 pm.

Blood lipids, especially triglycerides, are susceptible to elevated levels due to the fat content of food. Therefore, you should not eat for 12 hours before the blood draw, drink plenty of water for 8 hours, and drink alcohol for 3 days.

Do not eat animal food, because animal fat, offal, bone marrow and other cholesterol content are very high, so as to avoid the temporary increase of blood lipids in the short term due to fat and alcohol in food. It is best to avoid activities such as potlucks that may cause excessive fat intake for 3 days before the blood draw.

The best time to test fasting blood sugar is between 8 and 12 hours after meals, the night before blood drawing, you should eat normally, meals should be light, do not drink alcohol, do not drink coffee and strong tea after meals, do not eat after 10 o'clock, and ensure adequate sleep.

When you wake up the next morning, don't eat anything, drink little or no water, and at the same time, avoid being too emotional and doing too strenuous activities, and the blood draw time is best at 6 or 8 o'clock in the morning, so that the blood sample can reflect the real condition of the body.

12 to 14 hours. Not all tests require fasting blood draws, and only when biochemical items such as blood sugar and lipids are checked, fasting blood is required. Fasting blood refers to the venous blood drawn about 12 to 14 hours before the meal in the early morning, because the digestion and absorption activities of the gastrointestinal tract have been basically completed during this period, and the various components in the blood are relatively constant, so the measured values can more truly reflect the changes in the body and help to diagnose the disease.

It is best to draw blood on an empty stomach but not on an excessive fasting (more than 14 hours before the previous meal), because excessive fasting will lead to an increase in bilirubin, triglycerides, glycerol, and free fatty acids in the blood, and bilirubin can be doubled after 48 hours of fasting, and excessive fasting can also lead to hypoglycemia.

Guidance: It is recommended that you should get enough sleep at night before blood drawing, and should not do strenuous exercise in the morning. Because strenuous exercise can temporarily increase alanine aminotransferase (ALT) and aspartate aminotransferase (AST), it can also cause changes in blood potassium, sodium, blood sugar and other components, affecting the measurement results. In addition, it is also necessary to relax when blood is drawn, because fear will cause blood vessels to constrict, making it more difficult to collect blood.

Blood donation is not harmful to health. But 400cc is not a lot. Let's go back to 200 next time.

Fasting blood collection is a traditional practice of blood transfusion medicine, and its purpose is mainly to eliminate problems such as blood dilution and chyle blood to ensure blood quality. However, the disadvantage is that fasting is easy to lead to a relative decrease in blood sugar, and the blood volume decreases during blood collection, so it is often easy to cause mild or severe blood donation reactions in blood donors. The postprandial blood collection is a new concept of blood transfusion, because eating can not only increase blood sugar concentration, but also increase blood volume, so it can greatly reduce blood donation reactions, especially the occurrence of severe blood donation reactions, the key is to control the vegetarian nature of blood donation and eat, and eliminate the occurrence of chyle blood.

In order to verify the effect of postprandial blood donation, relevant experts conducted a comparative test on 979 fasting blood donors and 1716 postprandial blood donors, and the results were: there was no case of chyle blood; There were 3 cases of general blood donation reaction in fasting blood donors and only 1 case of postprandial blood donation. There was one case of severe blood donation reaction among fasting blood donors, and none of the postprandial blood donors. This shows that it is feasible to donate blood after meals, as long as the first two meals of blood donation are mainly vegetarian, it can not only ensure blood quality, but also solve the problem of blood donation reaction.

2.Before blood lipid checks, do not eat foods with high fat content, such as shabu-shabu;

3.Before checking cholesterol, it is necessary to eat less foods with high cholesterol content such as eggs, which will affect the composition of the blood and cause "misjudgment".
