The diagnostic test for lactose intolerance is performed in the Laboratorio Unilabs - Barcelona (Av. Meridiana), using a breath sample (exhaled air) that detects hydrogen produced by intestinal bacteria in the exhaled air. This test includes:

• Breath test kit
• Analysis to detect lactose intolerance
• Detailed diagnostic report: results to determine lactose intolerance

To take the breath test, you need to be fasting and have avoided taking certain medications such as:

• 4 Weeks before the test:
  • Antibiotics
  • Probiotics and prebiotics
• 1 Week before the test:
  • Prokinetics (Motilium, Cidine, Blaston, or similar)
  • Laxatives (including Plantaben or other fibers)
  • Suppositories
  • Medications for gas

To ensure you know all the details of this analysis, we explain step by step how the procedure works, the pre-test instructions, and the wait time until results are obtained. 

The process for this test involves these simple steps:

1. To begin the sample collection, you will need to blow into a small tube that analyzes the hydrogen in your breath. This is the baseline measurement.
2. After the baseline measurement, you will need to blow into the tube again after drinking a solution of the substrate. This process will be repeated several times, each time into a different tube. Measurements are taken every 15 to 30 minutes over a period of 1 to 2 and a half hours.
3. Once the breath sample collection is complete, the samples will be sent to the laboratory for analysis and result generation.
