I have to take a blood test tomorrow, can I eat the fruit tonight?

It depends on what the items of your blood test are, because the current experience of routine blood tests will include a "blood sugar" measurement, and there are two indicators of blood sugar measurement, one is fasting blood glucose, and the other is blood sugar 2 hours after meals.

Fasting blood sugar requires that you should not eat after 8 p.m. the night before, so that the test is accurate.

The blood sugar 2 hours after a meal can only be measured 2 hours after eating, and the content of grapes eaten must be determined if it is correct, which is more difficult to do, so it is generally measured fasting blood sugar. So you can't eat before a blood test.

It has no effect on checking liver function.

Liver function tests generally don't require you to go for a test in the morning. It should be said that among all the blood test items, only those who check blood sugar will be required to check in the morning, just to ensure that they have an empty stomach while not making people faint from hunger.

As long as you don't eat anything toxic before the liver function test, it will not affect the results.

In addition, if the liver function test is not normal, it is generally not immediately qualitative, and the doctor will ask you if you have taken any recent medications (some drugs have an effect on liver function), and will not be determined until all interfering factors are removed. So eating has no effect on liver function.

In addition, if you test blood lipids, you will be asked not to eat too greasy things the day before, otherwise lipid metabolism will take a certain period, which will affect the accuracy of the measurement results.

Therefore, in order to avoid donating blood, some people will eat a lot of greasy things the day before, in the hope that the blood lipids will not be normal and avoid responsibility (-

It depends.

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.

It depends on what you test, if it is a blood lipid item, it is best not to eat meat, because then the blood drawn tomorrow morning will be "lipid blood".

It's best not to eat anything, except for dinner, don't eat breakfast the next day, because the blood test technique is not very accurate, in order not to affect the results, it's better not to eat, no, liver function and the like can't eat breakfast, if breakfast can be eaten, it doesn't matter what the night is eliminated, just eat it if you want!

Depending on what items you test, if it is blood sugar, blood lipids, etc., then it is recommended to have a light diet and don't eat fruits, although fruits have little effect. The most important thing is not to drink water or eat anything on the morning of the test so that you can get the real test results.

No, to put it simply, you don't want to suspect the doctor that you have DM.

Depending on when you eat supper, you generally need to keep an empty stomach for 8 to 10 hours for a blood test, and after 10 o'clock in the evening before the blood is drawn, don't eat again! Of course, for the sake of the accuracy of the check, don't drink any more water! If you have a urine test, don't urinate first when you get up in the morning, and wait until you go to the hospital to leave your morning urine, and then solve it!

If it is a physical examination, it is best to have an empty stomach and hold your urine! There is a lot of data hidden in a person's blood, and if you eat something, it can affect the results of the test. For example, after eating, the body absorbs the sugar content of the food, will the blood sugar rise?

Then, when the doctor looks at the results and judges, he thinks that your blood sugar is high and there is a risk of high blood sugar, but in fact you don't. It can lead to errors in judgment and cause unnecessary trouble. <>

Do not drink heavily for 3 days before the blood draw. The main ingredient of alcohol is ethanol, which can be converted into aldehydes in the liver, which can cause degeneration or necrosis of liver cells, so the results will be biased when liver function is checked. Alcohol has a paralyzing effect, the kidney tissue is affected, the excretion of harmful substances such as urea nitrogen is affected, and it accumulates in the body, and there is a transient high level, and if it is only checked once, it is likely to be misdiagnosed as kidney disease.

Drinking alcohol can also affect the concentration of blood lipids, which can lead to errors in the test results, so you should not drink a lot of alcohol in the 3 days before the blood draw, and you should not even drink a small amount of alcohol within 24 hours. <>

Avoid high-fat, high-protein diets for 3 days before the test. Urea nitrogen and serum creatinine of renal function test indicators will be transiently increased due to eating, especially eating meat and high-protein foods, which will affect the judgment of results. Animals are high in cholesterol such as internal organs, brain, bone marrow, and fat, and the fat and alcohol in these foods will also have a temporary effect on blood lipids.

Therefore, a high-fat, high-protein diet should be avoided for three days before the blood is drawn. Do not do strenuous exercise such as running, playing ball, high jump, etc., 2 to 3 days before the blood test. Because the amount of exercise is too large and too vigorous, the lipase activity in the fat will increase, and the blood lipids will decrease accordingly, which will also have a certain impact on the reliability of the test results.

It doesn't affect much, as long as you don't eat too greasy, it's fine, and as long as you do it a little later the next day, it's okay after more than eight hours.

Of course, as long as you don't eat very greasy things at night, you have to be light, it doesn't matter if you don't eat before the physical examination, it will affect your blood lipid level, and the simple blood routine is not affected, if there are liver function, blood lipids and other tests, it will have a certain impact.

Possibly, so be sure to pay attention to your food choices and don't continue eating after 12 p.m.
