What condition results in the highest serum level of transaminases?

Acute hepatitis is known to result in significantly elevated serum levels of transaminases, particularly alanine aminotransferase (ALT) and aspartate aminotransferase (AST). During an acute inflammatory process in the liver, such as viral or toxic hepatitis, there is extensive hepatocellular damage. This damage leads to the release of these enzymes into the bloodstream, causing markedly high levels compared to other liver conditions.

In contrast, chronic hepatitis tends to result in more moderate and stable elevations in transaminases, as the liver damage occurs over a more extended period and in a more regulated manner. Alcoholic liver disease and non-alcoholic steatohepatitis, while also associated with elevated transaminases, generally lead to lower peak levels compared to acute hepatitis due to the nature and extent of liver injury in these conditions. Consequently, acute hepatitis is characterized by the most significant burst of enzyme release, leading to the highest serum levels of transaminases.
