ALT (Liver)
ALT is an enzyme measured on many liver panels. An elevated result can have multiple explanations and cannot identify a cause by itself.
SomaZeus display band
For care decisions, use the interval printed by the reporting lab and ask your clinician. Labs, assay methods, and individual context vary; the numbers below are SomaZeus display guidance.
Watch points
- Watch point 1: at or above 200 U/L
- Watch point 2: at or above 100 U/L
- Watch point 3: at or above 60 U/L
SomaZeus uses the same watch points for men and women in this display.
Why hard-training athletes watch it
Training, alcohol, medications, supplements, illness, and other factors may coincide with a change. Log the recent context and review it with a clinician rather than assigning one cause.
When to retest
Ask your clinician whether and when a repeat is appropriate, and share the draw timing plus recent training, alcohol, medication, and supplement context.
Talk to your clinician
A clinician can interpret ALT beside AST, the rest of the panel, symptoms, and the reporting lab interval.
