Alanine aminotransferase 55 U/L is not normal and is considered high. Alanine aminotransferase, also called glutamate aminotransferase, is an important indicator of liver function. There are more indicators for liver function test, besides glutamate aminotransferase, there are also indicators such as glutamic oxalacetic aminotransferase and alkaline phosphatase. Glutathione is mainly distributed on the surface of liver cells, and it is an indicator of abnormal liver function due to liver damage or abnormal liver function, which leads to elevated concentrations in the cord blood, and is generally considered to be more sensitive to glutathione. In addition to abnormal function of the liver itself, other causes such as cold, fever, exercise, exertion or being affected by other diseases can also cause an increase in GLTA. If you find an elevated ALT, you should check the liver itself for lesions, such as liver ultrasound or CT to check for hepatitis, liver gallstones, tumors and other related lesions. It is important to check whether other organs of the body also have lesions, or whether there is any recent exertion, cold, etc. In addition, elevated liver glutathione should be dynamically observed, such as after taking medication or rest, to see if the results recover or improve. If it is further elevated, further examination and treatment are needed. Elevated GLT is also associated with autoimmune diseases, also called autoimmune hepatitis, or viral hepatitis, which can cause elevated glutathione.
