Glutathione is a type of transaminase and is an important indicator of liver function. However, a high or low GhG ratio indicates abnormal liver function. The normal ratio of GLG is 0.8-1.5. If the ratio is less than 1.0, it indicates a chronic, mild or acute hepatitis. When the GHC ratio is greater than 1.0, it indicates alcoholic liver disease or drug-related liver disease. If the GhG ratio is greater than 2, it indicates severe hepatitis or even liver cancer. Therefore, when the GHC ratio is low, timely examination and treatment are needed. It is recommended to check the liver function, followed by the full range of hepatitis, including hepatitis B, hepatitis C, hepatitis A and hepatitis E. Patients are also advised not to blindly utilize enzyme-lowering drugs until the cause is clearly identified, in order to cover up the real situation of the disease. After finding the cause, we should treat both the symptoms and the root cause, and actively treat the original disease while lowering enzymes to avoid the rebound of the disease.
