What are the five tests of liver function?

The so-called five tests of liver function are mainly aimed at the inspection of human liver metabolites, which are divided into five substances: albumin, transaminase, bilirubin, phosphatase and collagen. The abnormality of different substances reflects different liver tissue damage.

1, albumin: It mainly includes prealbumin, albumin, cholinesterase, total protein and other substances, so these substances are indispensable for the synthesis of protein in the liver, so the abnormality of these substances can reflect the abnormality of protein synthesis and metabolic function of hepatocytes.

2. Transaminase: mainly including alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, adenosine deaminase, etc. Because transaminase is the "catalyst" of human metabolism and exists in liver cells, it can be used to reflect whether liver cells are damaged and the diagnosis of the degree of damage.

3. Bilirubin: It mainly includes direct bilirubin (DBIL), indirect bilirubin, blood ammonia (NH3), total bilirubin, etc. When the excretion and secretion of the human body and the detoxification function of the liver appear obstacles, these substances will be abnormal.

4. Phosphatase: Alkaline phosphatase (ALP), glutamate transpeptidase (GGT), nucleotidase and other substances are mostly distributed in the bile duct epithelium of the liver. The abnormality of these phosphatase indexes can reflect the disorder of bile secretion function in human liver.

5. Collagen: type III procollagen, type IV procollagen, hyaluronic acid, etc. It is a necessary substance for liver fibrosis and cirrhosis in human body, and can be used to diagnose the development trend of liver fibrosis and cirrhosis in human body at will.

The most harmful behavior to the liver:

1, lack of sleep. Nowadays, many people have the habit of working or playing at night, but staying up late is the easiest way to get liver disease. The reason is that the human body will enter the self-repair mode during sleep, and staying up late often not only leads to insufficient sleep, but also affects the self-repair of the liver at night.

People who have been infected with hepatitis virus will get worse if they stay up late. Professor Neil Colin, an expert from the American Sleep Association, said that "late sleepers" should try to adjust their work and rest schedules, and it is best to fall asleep before 1 1 every night to ensure 7-8 hours of adequate sleep every night, so as to effectively detoxify the liver and ensure overall health.

2. Don't urinate in time after getting up in the morning. Dr Daniel Paradi, an expert from the European Association for Liver Research, said that detoxification in the body can be carried out through urination, perspiration and defecation. Urinating as soon as possible after getting up in the morning can discharge toxins accumulated overnight in time to avoid toxins staying in the body and causing liver "poisoning".

3, overeating. Many people know that eating too much will increase the burden on the stomach and induce fatty liver. Dr Paradi pointed out that overeating is not only harmful to gastrointestinal health, but also easy to lead to a large increase of free radicals in the body. The key function of the liver is to help the human body deal with free radicals, eliminate toxins and purify the blood. The more free radicals in the human body, the more serious the damage to liver function.

4. Don't eat breakfast. Nutrition experts say that eating breakfast helps to neutralize stomach acid, protect the liver and reduce the risk of diseases such as pancreatitis, diabetes, gallstones and constipation. Dr. Hermite Suri, a holistic nutritionist in Ontario, Canada, said that a healthy breakfast can prolong satiety and avoid liver damage.
