Among the biochemical tests, there are two types of aminotransferases: glutathione and glutamic oxalacetic transaminase. Most cases of elevated transaminases indicate liver damage, mainly due to viral liver injury, drug-related liver injury, alcoholic liver injury, toxic liver injury and autoimmune liver injury, and the first treatment should be liver protection and stabilization of liver cell membranes, as well as treatment for the cause. If the elevation of glutamic oxalacetic aminotransferase is greater than that of glutamic alanine aminotransferase, it indicates that the degree of liver injury is more serious, and treatment and observation of the condition should be intensified. If the patient has precordial discomfort and elevated glutathione and glutamic transaminase, other cardiac enzymes should also be examined. If they are elevated simultaneously, it cannot be ruled out that the patient has heart disease or even myocardial infarction, and prompt medical attention should be sought.
