The normal range of glutamic oxalacetic transaminase is 0-40U/L. When glutamic oxalacetic transaminase is 70U/L, it is not serious, it is mildly high and belongs to mild liver function damage. If hepatitis is diagnosed, further examination of hepatitis B DNA, hepatitis B triple system and ultrasound is needed to clarify whether there is cirrhosis and whether the virus is replicating, and if the virus is replicating, antiviral treatment is needed in time. If the examination does not reveal hepatitis, for normal people with elevated glutamic transaminase to 70U/L, it is mostly considered to be caused by liver function damage, which is related to unhealthy living habits in daily life, such as exertion, staying up late, taking drugs, drinking alcohol, etc. Patients should pay attention to the improvement of living habits, drink more water, urinate more, and ensure sufficient sleep. If the elevation is high, you can take drugs with liver nourishing and protecting effects such as diammonium glycyrrhizate enteric capsules and inosine tablets, and the glutamic transaminase will gradually return to normal.
