What are the normal liver function indicators?

The liver is an important detoxification organ in the human body, and people only know about the detoxification function of the liver. In fact, there are certain indicators for liver function. Exceeding or falling below the normal indicators is harmful to the liver. We should pay more attention to liver examinations on a daily basis, as well as pay attention to diet and rest in life. Not drinking, staying up late, and not getting angry are the basic elements for protecting the liver. So what are the liver function indicators of normal people?

Normal liver function

Liver function tests are tests that reflect the physiological function of the liver. Liver function tests often include ALT, AST, AST/ALT, GGT, ALP, TBILI, DBILI, IBILI, TP, ALB, GLB, A/G, LDH-L, Ch, SF, PA and other items. Understanding the standards of these test indicators will help people increase their understanding of liver function and diagnosis.

Basic meaning

Because the liver has various functions, there are many ways to test liver function. The tests related to liver function include serum protein test, common serum enzyme test, alkaline phosphatase (ALP) test, γ-transpeptidase (γ-GT) test, serum bilirubin test, CB/STB, alanine aminotransferase (ALT, GPT), aspartate aminotransferase (AST, GOT), etc. Understanding the normal values ​​of liver function and the standards and parameters of various tests will help increase the understanding and diagnosis of liver function.

Drinking alcohol can damage your liver

The view that drinking alcohol damages the liver has been recognized by the medical community. However, some people still think that liver damage can only be caused when drinking liquor or getting drunk. This view is wrong. The main component of wine is ethanol. After ethanol enters the human body, it will be metabolized into acetaldehyde, which can directly damage the structure and function of liver cells, leading to decreased liver function, especially the liver's metabolism of sugar, fat and protein. In addition, ethanol can increase the synthesis of oxygen free radicals that are toxic to the liver, accelerating the process of liver fibrosis. This will cause more severe liver damage.

reason

Liver function tests must be performed on an empty stomach, and the fasting time is generally 8-12 hours. This is especially true for those who are undergoing liver function tests for the first time.

Patients with liver disease are advised to abstain from alcohol the day before a blood test. This is because the values ​​of many items in liver function tests are related to diet. For example, drinking alcohol can easily increase the values ​​of certain serum enzymes, and eating greasy foods can increase blood lipids. Therefore, patients with liver disease must pay attention to fasting when undergoing examinations to ensure a scientific diagnosis.

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

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.

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

It is best not to drink alcohol before the test; avoid taking certain medications because they may affect the accuracy of liver function tests.

Liver function test is an important test to measure whether there is liver cell necrosis or inflammation in the liver. If you are infected with hepatitis B, you must not neglect regular check-ups.
