Whether or not a high GTA is serious depends on how much it is above the normal range, but a mild increase is generally not serious. There are many reasons for high glutathione, such as intense exercise before the test, or staying up late for a long time, poor rest, or drinking alcohol or eating too much fatty food before the test, and note that you need to fast for 4-8 hours before the test, all these reasons may cause glutathione to rise. Secondly, the onset of viral hepatitis such as hepatitis B and C can also cause damage to the liver, which can lead to elevated glutathione transaminase. No matter what the cause of the high GTA, you need to pay attention to it and receive timely treatment to avoid more damage to the body. The daily diet is not to eat foods that are easily inflammable or irritating, and not to drink alcohol, but to eat foods rich in vitamins, such as fresh fruits and vegetables.
