High ALT can be seen in acute and chronic viral hepatitis, non-viral liver disease, intra-hepatic and extra-hepatic cholestasis, etc. It is recommended to analyze and judge together with the results of ALT.
1. Acute and chronic viral hepatitis: when acute viral hepatitis occurs, ALT can be significantly elevated; when chronic viral hepatitis occurs, ALT can be mildly elevated.
2. Non-viral liver diseases: such as alcoholic liver disease, drug-induced hepatitis, fatty liver, hepatocellular carcinoma, etc., the alanine aminotransferase can be mildly elevated or normal.
3. Intrahepatic and extrahepatic cholestasis: ALT may be mildly elevated or normal.
Clinically, it is not recommended to look at certain test indicators in isolation, and it is recommended to analyze and judge them comprehensively by combining them with various test indicators such as AST, alkaline phosphatase, lactate dehydrogenase, etc. If necessary, it is recommended to carry out a systemic examination to clarify the cause of the disease and carry out targeted treatment in a timely manner.
