Aspartate aminotransferase (AST)

A liver-panel enzyme that can enter liver-cell injury context but is not liver-specific by itself.

What it is

AST is an enzyme often included in liver panels.^[1,2]

Why it matters

AST can rise in liver injury contexts and is usually interpreted with ALT and other tests.^[1,2]

What it affects

AST belongs in a pattern, not a one-number conclusion.^[1,2]

Interpretation traps

AST can be affected by non-liver context, so BioConst does not interpret personal AST values.^[1,2]
