Hepatic
ALT (Alanine Aminotransferase)
ALT is the most liver-specific of the routine liver enzymes.
Reference range
Adult reference: ~7–55 U/L. Functional optimization context only — not a diagnostic assertion. Range varies by lab, age, and sex.
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.
