Transaminases are a class of enzymes that catalyze the transfer of amino acids between amino acids and keto acids and are found primarily in liver cells. A transaminase test can provide insight into liver damage. Transaminases, which include glutamyltransferase, alanine aminotransferase, and aspartate aminotransferase, are found primarily in the body’s liver cells. If the liver cells are damaged, a large amount of transaminases will be released into the bloodstream, resulting in elevated levels of transaminases. Under normal circumstances, aminotransferase level is around 0-40U/L. If the actual value exceeds 40U/L, then it means that there is an abnormal liver function, which may be caused by staying up late, drinking alcohol and other bad habits, or it may be related to some liver diseases, such as viral hepatitis, alcoholic liver disease, fatty liver, cirrhosis and so on. However, this is not absolute, and patients are advised to go to the hospital in time for further examination to find out the cause of the disease, and then treat the cause with the help of the doctor.
