This test involves four steps:

1. The first blood test is taken on an empty stomach.

This is intended to measure your blood sugar while fasting. To avoid the consequences of feeling faint or ill while travelling to the lab, we advise that a relative or friend accompany you to drive you there and take you home.

2. Ingestion of a sweetened drink

3. Blood sample at H+1 (one hour after drinking the drink)

4. Blood test at H+2:

Two hours after drinking the drink, a third and final blood test will be performed.
