About AST (SGOT)
AST, also known as SGOT, is another liver enzyme checked alongside ALT, though it is less specific to the liver since it is also found in heart and muscle tissue. Comparing AST and ALT together helps your doctor understand the pattern of any liver stress.
No fasting is strictly required, and results are ready the same day, usually alongside your other liver markers.
How to Prepare
- No fasting required.
- Avoid strenuous exercise the day before, since it can raise results.
Frequently Asked Questions
What does AST (SGOT) measure?
It measures a liver enzyme also found in heart and muscle tissue, so it is usually interpreted together with ALT for a clearer liver-specific picture.
Do I need to fast before this test?
No strict fasting is required.
Why is AST less specific than ALT for liver problems?
Because AST is also present in heart and muscle tissue, a raised level does not automatically point to the liver alone.
What does a high AST to ALT ratio suggest?
Certain patterns, like AST higher than ALT, can point doctors toward specific causes such as alcohol-related liver stress, though full context is needed.
How soon will my report be ready?
Same day.
Is home sample collection available?
Yes, in all City Care Lab service areas.
