Glutamic oxaloacetic aminotransferase, also known as aspartate aminotransferase, has a normal value of 0-40 U/L and is mostly used for liver function tests. Under normal conditions, glutamic oxalacetic aminotransferase is low in the serum. If there is a transient increase, it may be caused by some poor lifestyle habits. If it is persistently high, it suggests that there may be damage to the main distribution sites, such as heart muscle, liver, skeletal muscle, etc. I. Physiological factors 1, bad habits: it may be that the patient’s recent irregular work and rest, staying up too late, excessive exercise, or the recent large amount of alcohol, etc. lead to a transient increase in glutamate transaminase, usually after adjusting lifestyle habits, can gradually return to normal levels; 2, drug effects: such as antibiotics, opioids, barbiturates, statins, and anti-inflammatory drugs such as aspirin, in the examination The use of drugs before the examination may cause the elevation of glutamic oxalacetic aminotransferase; 3, the impact of the examination: if the specimen hemolysis or contamination during the examination, may cause glutamic oxalacetic aminotransferase high. 2, disease factors 1, hepatobiliary diseases: such as acute and chronic viral hepatitis, alcoholic liver disease, drug hepatitis, fatty liver, cirrhosis, liver cancer and other liver diseases, as well as the acute stage of cholecystitis, cholelithiasis, biliary tumors and other diseases, when the liver and biliary cells are damaged, due to the increase in cell membrane permeability, can make the glutathione transaminase content rise; 2, heart disease: acute myocardial infarction can appear after the increase in glutathione transaminase If it increases again, it indicates the expansion of infarct or the occurrence of a new infarct. In addition, cardiac diseases such as myocarditis and heart failure can also cause elevated glutathione; 3. Other diseases: skeletal muscle diseases such as acute soft tissue injury, dermatomyositis and progressive muscular atrophy can also show mild elevation of glutathione. Since high glutamic transaminase can be caused by a variety of reasons, this test alone cannot clarify what is going on. It is necessary to describe the recent physical condition in detail to the doctor and improve the relevant tests for differential diagnosis.
