A low glutathione transaminase has no clinical significance and would not indicate any disease, so there is no harm to talk about. In the blood test, there is basically a normal reference range, some indicators are meaningful when high and meaningless when low, and some indicators are meaningful when high and meaningful when low. Glutamic oxalacetic transaminase is one of those that are meaningful when high and meaningless when low, and low does not mean anything, nor does it represent anything harmful. Glutathione is mainly found in the muscles of the heart, that is, in the heart muscle, but also in the liver, skeletal muscle and other places, when there is damage to these places, such as myocardial infarction, liver cell damage, necrosis, skeletal muscle injury, will cause an increase in glutathione, blood tests can be found when the liver function and muscle enzyme spectrum. An elevated level means there is damage to the heart, liver or skeletal muscle, and the doctor will need to determine where the problem is in conjunction with the patient’s condition.
