AST as an Inflammatory Marker
The aspartate aminotransferase (AST) is an enzyme that is released in the blood when the body experiences inflammation. It is typically used as an inflammatory marker, alongside other tests, to help diagnose and monitor various conditions. AST levels in the blood can be elevated by a variety of conditions, including infection, trauma, and certain chronic diseases.
AST stands for aspartate aminotransferase and is an enzyme found primarily in the liver, heart, and skeletal muscle. When the body experiences inflammation, AST is released into the blood in increased quantities. This increase in AST levels is then used to diagnose and monitor the presence of inflammation in the body.
The AST test is typically used in conjunction with other tests that measure inflammation, such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). AST levels are usually measured in IU/L (international units per liter). Normal AST levels range from 10 to 40 IU/L, although this can vary slightly depending on the laboratory.
Elevated AST levels can be caused by a variety of conditions, including infection, trauma, and certain chronic diseases. Liver diseases such as hepatitis and cirrhosis can also cause an increase in AST levels. In addition, certain medications, such as statins, can also cause elevated AST levels.
In conclusion, AST is an important inflammatory marker that can be used to diagnose and monitor a variety of conditions. Elevated AST levels can be caused by a variety of conditions, including infection, trauma, and certain chronic diseases. It is important to discuss any concerns with your healthcare provider to determine the cause of elevated AST levels.
