Do you experience digestive discomfort after consuming milk or dairy products? This breath test allows for the precise and non-invasive identification of possible alterations in intestinal lactose absorption.
¿Where is it done?
We explain how it works, it's very simple:
1.- Buy your test online: once the payment is completed, you will receive a voucher in your email.
2.- Go to your nearest center: with your voucher (you can have it on your mobile), come to any of our Laboratorio Echevarne centers. No appointment needed.
3.- Professional sample collection: our specialized staff will take care of the sample extraction quickly and safely.
This breath test evaluates the intestine's ability to digest and absorb lactose, the sugar found in milk and its derivatives.
When lactose is not properly digested due to a lack of the enzyme lactase, it reaches the colon, where bacteria ferment it, producing gases such as hydrogen and/or methane that are detected in the breath.
The test measures these gases at different times after ingesting a lactose solution to determine if lactose intolerance exists.

This test is for you if:
• After consuming milk or dairy products you experience abdominal pain, gas, diarrhea, or nausea.
