ALT Evaluator
Metabolic Relevance
ALT is a marker of liver cell damage. Elevated levels may indicate fatty liver, insulin resistance, or liver inflammation - even within the traditional "normal" range.
Recommended testing frequency:
Annually, or every 3 months if fatty liver is present
Did you know?
Traditional lab limits (40 U/L for men) miss 57% of fatty liver cases. Research shows that values above 25 U/L may already indicate fatty liver.
Optimal ALT levels are between 15-20 U/L, indicating healthy liver function.
