ALT (Alanine Aminotransferase)

ALT is the most liver-specific of the routine liver enzymes.

Reference range

Reference ranges vary by lab, age and sex. Your own lab report carries the authoritative range, and your clinician reads it with you.

Why it matters

ALT is the headline liver enzyme on any longevity panel. Persistent elevation — even within the standard reference range — is a recognized signal of metabolic-associated liver disease. REVRCEL panels read ALT alongside body composition, fasting insulin, and lipid markers to interpret the trend.

How REVRCEL clinicians read it

Read against AST, GGT, body composition, and metabolic markers. Act on the pattern, not the single value.
