When to get this test
Liver health
Elevated AST can indicate liver inflammation or damage as part of a liver evaluation.
Muscle and tissue injury
Since AST is also in muscle and other tissues, it can reflect injury beyond the liver.
Monitoring and screening
Commonly included in panels to monitor liver conditions or medication effects.
How to prepare

No special preparation needed.
Common questions
Why is AST checked with ALT?
AST and ALT are usually read together because their pattern helps point to the source and degree of liver stress. ALT is more liver-specific than AST.
Can exercise affect AST?
Yes, strenuous exercise or muscle injury can raise AST since it is also present in muscle tissue. This is considered when interpreting results.
