Do men need to fast when checking liver function?

There are many organs in the human body, and these organs play an important role in people's daily life. When a person has a problem with an organ, some physical examinations are necessary. When there is a problem with liver function, liver function must be checked. So, do you need to fast when checking liver function? According to practice, you need to fast when checking liver function. Next, let's learn about whether you need to fast when checking liver function. I hope the following content will be helpful to everyone.

Liver function tests are performed by various biochemical tests to detect various indicators related to liver metabolism to reflect the basic status of liver function. Since liver functions are diverse, there are many methods for liver function tests. The specific tests should be selected based on the medical history and symptoms to help diagnose and evaluate liver function.

Due to the diverse functions of the liver, there are many methods for testing liver function. Protein tests related to liver function include serum total protein, albumin to globulin ratio, serum turbidity and flocculent test, and alpha-fetoprotein test; serum enzymes related to liver disease include alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase; tests related to biotransformation and excretion include sodium sulfobromophthalide retention test; and tests related to bile pigment metabolism include bilirubin quantification and urine tricholine test. These test items can be accurately tested by blood tests.

Liver function tests are an auxiliary means of diagnosing liver and gallbladder diseases. If a correct diagnosis is to be made, a comprehensive analysis must be conducted in combination with the patient's medical history, physical examination, and imaging examinations. It should also be pointed out that there are many items in liver function tests, but not every test item needs to be done. Usually, doctors will select a group or several of the tests based on the patient's medical history and symptoms.

Reasons for fasting

1. You cannot eat or drink water before the liver function test and must stay on an empty stomach for 8 to 12 hours.

2. Do not drink alcohol, eat spicy food, or greasy food the night before the liver function test. You must eat light food.

3. Do not stay up late or take medicine the night before the liver function test, otherwise it may lead to elevated transaminase and abnormal liver function test.

Liver function is a routine examination item. All liver function tests require fasting blood draws. This is because normal human blood contains a certain amount of large molecular β and γ globulins, which can combine with certain chemical reagents to precipitate, while small molecular albumin and α1-globulin can prevent the formation of precipitation. When the specified chemical reagents are added to the normal human serum, no precipitation or slight precipitation occurs due to the inhibitory effect of albumin. Since the serum albumin of hepatitis B patients decreases and β and γ globulins increase, obvious precipitation occurs after adding chemical reagents to their serum.

Do you need to fast when checking liver function? Through the above reading, we can also get the answer we want. Then we should pay more attention to our physical health in life. No matter how busy we are at work, we should pay attention to our diet and work and rest time. Go to bed on time and it is best not to stay up late unless it is a special situation.
