What should I pay attention to before liver function test?

Regular physical examinations are a very important part of modern life, because they can tell the actual health status of the body and play a certain basic role in the early detection and treatment of major diseases. Liver function test is an essential item in physical examination, but liver function test is relatively strict and requires a lot of attention. Let’s take a look at what to pay attention to before liver function test?

1. Liver function tests must be performed on an empty stomach, otherwise the chemical reaction produced after food enters the body will affect the accuracy of the test results. Therefore, you need to fast within 8 to 12 hours before the liver function test to avoid affecting the results and causing misdiagnosis.

2. It is best not to eat too greasy or spicy food the night before the liver function test. Such food can significantly increase the blood lipid test. Therefore, it is best to refrain from eating high-fat food 10 hours before blood collection.

3. It is advisable to eat some light food before the liver function test; it is best not to eat foods rich in carotene and lutein, because they may make the serum yellow and affect the jaundice index measurement results.

4. Pay attention to the medication you take before checking liver function. For example, drugs such as Atapine and vitamin D will have a certain impact on the jaundice index.

5. If you have a cold before the liver function test, it is best to wait 7 days after the cold is cured before the test, because the cold may affect the liver function test results.

6. Before the liver function test, make sure to get enough sleep, avoid strenuous exercise, and do not drink alcohol within 24 to 48 hours before the test. Strenuous exercise and alcohol can affect the value of transaminase.

Routine liver function tests require drawing venous blood, about 2 or 3 ml is enough, and the test must be done on an empty stomach. Most hospitals can give results on the same day. It is recommended to have liver function tests in the morning so that the results can be obtained in the afternoon.
