Albuminous aminotransferase below 8 U/L is not serious. Glutaminase is found mainly in the liver and is one of the indicators of liver function tests. Under normal circumstances glutamine aminotransferase can be released into the blood in small amounts. When encountering laboriousness, staying up all night, drinking alcohol, staying up all night and other triggers, liver function is affected possibly leading to a mild elevation of alanine aminotransferase; when there are viral hepatitis, drug-induced hepatic necrosis, cirrhosis, hepatocellular carcinoma, etc., the destruction of a large number of liver cells will lead to a significant increase in the aminotransferase in the blood. The normal reference range for alanine aminotransferase is 0 to 40 U/L, so an alanine aminotransferase result of 8 U/L is within the normal reference range, so it is not considered serious. The alanine aminotransferase result alone cannot fully determine the status of liver function, but also needs to be combined with other results of liver function as well as liver ultrasound and other items to make a judgment.
