Organ function
ALT
Also written as Alanine aminotransferase.
Core panel — run every month
What it indicates
An enzyme found mainly in liver cells and released when they are disturbed.
Why a series helps
ALT responds to recent alcohol, medication and hard exercise, so one raised reading is common and a sustained pattern is a different thing.
What this page does not tell you
What a particular ALT result means depends on you: your history, your medication, why the test was taken. Ziro does not interpret results for individuals and does not diagnose. If something in your results warrants a conversation, that conversation is with a doctor, and your results are downloadable so you can bring them.
