ALT, alanine aminotransferase, is a common enzyme in the cytoplasm of liver cells. Serum ALT is an important data in liver function tests, and its elevation is clinically significant, and it is the most commonly used enzyme indicator to respond to the function of hepatocytes in clinical practice.
The normal value of alanine aminotransferase is usually between 0 and 40 U/L. When hepatocytes are damaged, alanine aminotransferase in the cytoplasm is released into the blood stream, which elevates serum ALT. Therefore, serum ALT is mainly used to check the function of the liver, and when serum ALT is elevated, it can indicate that hepatocytes are damaged.
Common causes of elevated serum ALT include viral hepatitis, cirrhosis, and alcoholic liver disease. Clinically, if the serum ALT is elevated, it is necessary to further improve the examination under the guidance of the doctor, so as to clarify the cause of the disease for treatment.
