Gamma GT test: what it is for

GGT, or gamma GT, is an enzyme of the liver and the bile ducts. It is the liver test that reacts most to alcohol, but it also often rises with a few extra kilos or with some medicines. If it is high, one of these is usually the cause.

Why it is done

With alcohol it moves before the transaminases do. That is why it helps show where a liver problem comes from.

It matters beyond the liver too: in studies, a high GGT is linked to more health risks over the years. It often comes down once the cause goes.

How the gamma GT test is done

It is a blood test, done at a Bianalisi lab without a prescription. You can add other tests to the same draw.

Questions about the gamma GT test.

Do I need to fast for a gamma GT test? It is usually done fasting, together with the other liver tests. Avoid alcohol in the days before: gamma GT is very sensitive to alcohol.

How much does the gamma GT test cost? €3.93, from Bianalisi’s private list for Lombardy. You pay at the desk on the day of the draw, not online.
