An alanine aminotransferase of 63 U/L is not normal. Glutaminase is mainly found in various cells, predominantly liver cells. When the liver is damaged, glutaminase is released into the bloodstream, at which point serum testing will show a significant or exponential increase. The normal reference value of alanine aminotransferase is 0~40 U/L. If it is increased, it may be due to liver damage, such as chronic hepatitis B, primary biliary cirrhosis, etc., or affected by some other extra-hepatic factors, such as malnutrition, heavy alcohol abuse, or taking drugs such as chlorpromazine, quinine, salicylic acid preparation, etc., which impairs the liver function and raises the alanine aminotransferase in the blood. Albumin transaminase 63U/L can not directly diagnose the disease, should be based on clinical symptoms and other test results of comprehensive diagnosis, cooperate with the doctor treatment, to avoid delaying the disease.
