Name Time Method Main Objective: The primary objective is to demonstrate non ?inferiority of Gaxilose test, compared with Hydrogen Breath Test (HBT) using a validated method, of the impact on diagnostic thinking for the diagnosis of hypolactasia.;Secondary Objective: 1. to demonstrate non ?inferiority of Gaxilose test, compared with Hydrogen Breath Test (HBT), on the impact on patient management for the diagnosis of hypolactasia; <br>2. to demonstrate Gaxilose test reproducibility with urine accumulated from 0-4h after Gaxilose administration; <br>3. to demonstrate Gaxilose test reproducibility with urine accumulated from 0-5h after Gaxilose administration; <br>4. safety assessments.;Primary end point(s): To analyse the change in diagnostic certainty and in patient management consequent to HBT or Gaxilose test implementation in the clinical practice.;Timepoint(s) of evaluation of this end point: - Visual Analogue Scale (VAS) pre-test and post-test.<br>- Intended management pre-test and post-test questionnaires.
