The 2 liver function tests generally refer to the detection of glutamic aminotransferase and glutamic oxalacetic aminotransferase, both of which have normal values of 0-40 u/L. These two enzymes are the two most basic indicators of liver function tests, and the abnormal elevation of glutamic aminotransferase and glutamic oxalacetic aminotransferase can be used to determine whether the metabolic function of the liver is normal, whether the liver is damaged, and the severity of liver damage. Reasons for abnormally elevated transaminases 1, physiological elevation: can be caused by heavy drinking, strenuous exercise, lack of sleep, taking drugs, etc., mostly mildly elevated; 2, pathological elevation: usually caused by various acute and chronic hepatitis, liver cirrhosis, liver cancer, etc., manifested as different degrees of elevated transaminases. Treatment measures should be determined by professional doctors to determine the specific causes of elevated aminotransferases and then carry out treatment. If the aminotransferases are elevated due to physiological factors, they will usually decrease naturally with the recovery of damaged tissues and return to normal levels, but attention should be paid to avoid staying up late, quit smoking and drinking, maintain a good work and rest schedule, and review them in a timely manner. However, if the aminotransferase is elevated due to pathological factors, anti-viral, enzyme-lowering and hepatoprotective treatment should be carried out according to medical advice. For example, drugs such as entecavir and tenofovir can be used to effectively inhibit the replication of hepatitis B virus and improve the function of the liver; a low-fat diet and exercise can be used to improve fatty liver; liver-protective drugs such as compound glycyrrhetinic acid tablets and liver protection tablets can also be used to protect the function of the liver. Caution: The results of the 2 liver function tests alone cannot be used to fully reflect liver function. To fully assess the functional status of the liver, a combination of lipoproteins, coagulation function, liver ultrasound, CT, MRI and other indicators of liver function is needed.
