Does liver function test require fasting?

I believe that many friends are usually asked by the company to have a liver function test after passing an interview. Because of the occurrence of hepatitis B, many friends feel lingering fear, so all walks of life pay more attention to liver function tests. But many friends are not particularly clear about the specific test of liver function, so does the liver function test require fasting? In the next time, please join me in the following content.

According to liver disease experts, liver function tests must be done on an empty stomach, because different precipitations will occur in the components of serum after eating before the test. After adding chemical reagents, even normal people's serum will release different degrees of precipitation. Especially after eating high-fat, high-protein foods, the precipitation is more obvious, which can easily misdiagnose a normal person and affect the accuracy of the test results. Therefore, you must fast for 8 to 12 hours before a liver function test.

In addition, before the liver function test, you must not only be on an empty stomach, but also be prohibited from drinking water. The patient is prohibited from drinking alcohol, eating high-fat, high-protein foods, and doing strenuous exercise the day before the examination. These will affect the results of the liver function test, so the patient must pay attention before the liver function test.

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

How much does a liver function test cost?

Liver function tests are indicators for understanding whether there is liver disease, the extent of liver damage, as well as identifying the cause of liver disease and determining the prognosis. Due to the diversity of liver function test indicators, different charging standards are applied to different test items. The cost of routine liver function tests ranges from tens to two hundred yuan.

Through the above paragraphs, I believe that most of you have a deeper understanding of whether fasting is required for liver function tests. Of course, I would like to remind you that when we are going to do liver function tests, we must follow the steps on the checklist completely. Don't act on your own or be clever, because this test is not only for yourself but also for others.
