Normal value of liver function index
There are many indexes of liver function. Knowing the normal values of these indexes is of great significance to interpret the liver function test sheet and judge whether the liver is healthy or not.
1, normal value of liver function index-aspartate aminotransferase (AST):
The normal value of aspartate aminotransferase is 8-40 u/L. When alanine aminotransferase is obviously increased, the ratio of aspartate aminotransferase to alanine aminotransferase is >; 1, indicating liver parenchyma damage.
2. Normal value of liver function index-alanine aminotransferase (ALT)
The reference value of male is 5-40 U/L, and that of female is 5-35 U/L.. Alanine aminotransferase (ALT) is the main item to diagnose the substantial damage of liver cells, and its level is often parallel to the severity of the disease. When alanine aminotransferase test results deviate from the normal value of liver function test, it may be that there is something wrong with the liver.
3. Normal values of liver function indexes-total protein (TP), albumin (A) and globulin (G)
The normal values of total protein (TP) are 64-83 g/L for sitting position, 60-78 g/L for lying position, 35-52g/L for albumin (a), 22-38g/L for globulin (g) and 65,438 for albumin (A)/ globulin (g).
4. Normal value of liver function index-alkaline phosphatase (ALP)
Normal reference value for adults: 40- 150 u/l alkaline phosphatase (ALP) is mainly used for the examination of obstructive jaundice, primary liver cancer, secondary liver cancer and cholestatic hepatitis.
5. Liver function index-normal value of glutamyltransferase (GGT)
Male: 1 1-50 U/L, female: 7-32u/L GGT is not as good as alanine aminotransferase in reflecting hepatocyte necrosis damage, but it has certain significance in differentiating jaundice.
6, liver function indicators-serum total bilirubin and direct bilirubin are normal.
Causes of high liver function index
There are many reasons for abnormal liver function indexes in daily life, and different reasons lead to different severity. If it is only non-pathological liver injury, patients can recover as long as they get rid of bad living habits; If it is pathological liver injury, you must go to a regular hospital in time to avoid delaying your illness.
1, overwork: overwork will destroy the relatively balanced immune state of human body, increase the burden on the liver, and lead to abnormal liver function.
2, diet: drinking or eating greasy, fried, spicy food, will increase the burden of gastrointestinal and liver metabolism, causing abnormal liver function.
3. Change the environment: change the original living habits and living environment, such as business trips and tourism, which leads to internal environment disorder and abnormal liver function due to changes in raw water and soil conditions.
4. Viral hepatitis, fatty liver, alcoholic hepatitis, drug-induced liver, liver cirrhosis and liver cancer are the most common causes of abnormal liver function.
5. Mistaking or abusing drugs: A patient takes various self-made traditional Chinese medicine preparations in disorder, and over time, the patient has inflammation or poisoning, and the liver function damage is aggravated.
6. Suffering from other diseases: colds, diarrhea, cholecystitis, massive bleeding, gastrointestinal diseases, stones, tumors and chronic heart failure can also lead to liver function fluctuations.
What if the liver function index is too high?
When the liver function is abnormal, you must go to a large professional hospital for examination. If pathological liver injury is found, you must receive professional treatment in time to avoid delaying your illness. The treatment of liver disease is different from other diseases. Don't rush to see a doctor. Improper treatment may lead to the deterioration of the condition.
In daily life, we should also pay attention to forming good habits, which will also help alleviate the illness to some extent.
1, peace of mind. Chinese medicine believes that anger hurts the liver. For people with liver injury and abnormal liver function, we must be in a good mood, control anger and not get angry, otherwise liver qi will stagnate, liver fire will rise and liver disease will worsen.
2. Ensure rest. People with abnormal liver function should not engage in excessive and strenuous exercise and labor, otherwise it will increase the burden on the liver and be unfavorable to the condition.
3. Don't take medicine indiscriminately. Because many drugs are metabolized by the liver, and many drugs are harmful to the liver, which will cause drug damage to the liver and aggravate liver injury.
4. Check regularly. Check the liver function every half a month or 1 month to grasp the changes of the disease in time and provide basis for doctors' treatment.
5. Pay attention to a reasonable diet and reduce the intake of high-cholesterol foods. The following are dietary suggestions when liver function is abnormal:
Eat more foods rich in fiber.
Foods with very high fiber content such as coarse grains and bread can effectively reduce the content of low-density lipoprotein cholesterol in the human body. Nutrition experts point out that in order to achieve the effect of affecting cholesterol content, dietary fiber must reach 15~30 grams. Patients with high total cholesterol should eat more vegetables, fruits and bacteria and algae foods, such as konjac, auricularia, kelp, Undaria pinnatifida, onion, pumpkin, sweet potato, etc. These foods are rich in dietary fiber and help to excrete cholesterol.
Analysis of liver function test results
The analysis of liver function test results is actually not very complicated. As long as we clearly know what these tests represent and their normal values, we can finally get our liver function status through comparison.
Liver function examination mainly includes two aspects: 1, blood biochemical examination (liver function examination). 2. Detection of virus markers (five items of hepatitis B). The commonly used items of liver function examination mainly include total protein (TP), albumin (ALB) and globulin (GLO), which mainly reflect the synthetic function of the liver.
On the liver function test list, patients will see the data of alanine aminotransferase (ALT), aspartate aminotransferase (AST), transpeptidase (GGT) and lactate dehydrogenase (LDH). There are many kinds of enzymes in human body, among which ALT is the most in the liver, AST is the most in the heart, and AST is second only to ALT in the liver. Therefore, if the liver is damaged, the most sensitive reaction is ALT, and the value will rise rapidly. If ALT does not rise, AST rises, which may be a heart disease.
1. The items reflecting the synthetic reserve function of liver include prealbumin (PA), albumin (Alb), cholinesterase (CHE) and prothrombin time (PT).
They are routine tests that reflect the storage capacity of the liver by detecting its synthetic function. The decrease of prealbumin and albumin suggests that the ability of liver to synthesize protein is weakened. The increase of CHE can be seen in hyperthyroidism, diabetes, nephrotic syndrome and fatty liver. Prolonged prothrombin time (PT) indicates that the ability of the liver to synthesize various coagulation factors decreases.
2. The items reflecting liver fibrosis and cirrhosis include albumin (Alb), total bilirubin (TBil), monoamine oxidase (MAO) and serum protein electrophoresis.
When suffering from liver fibrosis or cirrhosis, serum albumin and total bilirubin will decrease, accompanied by monoamine oxidase increase.
3. The items reflecting the function of liver secretion and excretion include total bilirubin (TBil), direct bilirubin (DBil) and total bile acid (TBA).
