For normal people who have their blood drawn for liver function tests that suggest low glutamate transaminase as well as glutamic oxalacetic transaminase, there is generally not much pathological significance. For such cases, the normal values for glutamate and glutamic oxalacetic aminotransferase are between 0 and 40 U/L. If a patient’s transaminases are within this range, even if they are low, they generally do not indicate possible impairment of liver function or other diseases of the liver. If a patient’s aminotransferases exceed 40 U/L, the patient is considered to have liver damage. Transient liver function impairment, i.e., transient elevation of Ghrelin and Ghrelin, can occur after drinking alcohol, taking medication for a long time, or after exertion or staying up late. Patients need to identify whether this is due to these conditions, to underlying liver disease such as viral hepatitis or autoimmune hepatitis, or to fatty liver. If it is due to viral hepatitis or other underlying liver disease, further treatment will be required to address the cause. In patients with viral hepatitis, further blood tests for hepatitis B DNA or hepatitis C RNA are needed to see if the virus is replicating. If the virus is replicating, combined with liver function damage, then the patient should consider aggressive antiviral treatment.
