Organ function
GGT
Also written as Gamma-glutamyl transferase.
Core panel — run every month
What it indicates
A liver enzyme also involved in the bile ducts.
Why a series helps
It responds to alcohol across weeks, so a run of readings describes a habit rather than a weekend.
What this page does not tell you
What a particular GGT 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.
