Ordering the AST (SGOT) + ALT Liver Test
Ordering the AST (SGOT) + ALT Liver Test can help assess liver function by measuring specific enzymes in the blood. These enzymes, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), are released into the bloodstream when liver cells are damaged. Interestingly, these enzymes can also be elevated due to muscle injury, not just liver issues.
When you order this test, you can expect the following benefits:
- Helps detect liver inflammation or damage.
- Monitors the effectiveness of treatments for liver conditions.
- Assists in diagnosing liver diseases.
- Evaluates the impact of medications on the liver.
- Provides insight into unexplained fatigue or weakness.
Who Should Consider the Enzyme Evaluation Test
People experiencing persistent fatigue or unexplained weakness might find this test beneficial. For example, someone who feels unusually tired despite adequate rest may want to explore potential liver-related causes.
Consider ordering this test if you:
- Have a family history of liver disease.
- Experience persistent fatigue or weakness.
- Consume alcohol regularly.
- Have been exposed to hepatitis viruses.
- Are taking medications that may affect liver function.
Ordering this test can help identify liver enzyme levels, which may indicate liver damage or inflammation. Delaying this test could result in missing early signs of liver issues, which might lead to more complex health challenges later.
Preparing for the Enzyme Function Test
No fasting is required for the AST (SGOT) + ALT Liver Test, allowing for flexible scheduling. It’s important to follow any instructions from your doctor or healthcare professional to ensure the test is conducted properly.
