What should I pay attention to before liver function examination?

1, need an empty stomach before examination. Before liver function examination, you need to be on an empty stomach for 8- 12 hours, because after eating, especially drinking or eating a high-protein diet will lead to precipitation, which will lead to misdiagnosis, affect the doctor's judgment on the condition, and the treatment effect of patients will also be affected to some extent. 2, can't do strenuous exercise. Transaminase is one of the liver function tests, which often leads to the increase of transaminase, even in normal people, such as overwork, vomiting, strenuous exercise and so on. It will increase in a short time, so avoid strenuous exercise before liver function test. 3. Avoid taking drugs. Patients who need to take medicine for a long time should not take medicine before liver function examination. Taking some drugs may affect the accuracy of liver function test. 4. Choose a regular hospital. Irregular small hospitals, with incomplete medical equipment and unprofessional doctors, are prone to misdiagnosis and mistreatment. Only large regular liver disease hospitals can avoid these phenomena and ensure the accuracy and reliability of the examination results. According to the examination results, we can judge the condition, and when we need treatment, we should actively accept scientific treatment to avoid the aggravation of the condition, which will make the patient's condition develop to cirrhosis and liver cancer, thus increasing the difficulty and time of treatment, so it is very important to actively accept scientific treatment.
