Breath Analysis

Gastrointestinal Diseases

Gastrointestinal Diseases

Breath tests represent an effective way to investigate functional bloating, diarrhea, constipation, and suspected malabsorption, such as lactose and fructose. They are considered as a valid alternative to more invasive procedures. Approximately half the biomarkers identified in human breath air can be detected by laser spectroscopic techniques. TDLS is a robust and reliable technology able to sense many of these biomarkers such as methane (CH₄) and carbon dioxide (CO₂). The spectroscopic analysis of breath air can shorten the period needed to conduct tests from hours down to seconds and subsequently reduce mortality, prevent unnecessary hospitalization and greatly reduce medical expenses. Breath analysis is also seen as an effective diagnosis instrument helping in defining the appropriate antibiotic therapy at an early stage.

Elevated methane levels can suggest indigestion and are a possible indicator of fructosemia or lactose intolerance. Axetris Laser Gas Detection technology is capable of measuring methane with unprecedented precision at trace levels. Methane provides important insights into the performance of the carbohydrate metabolism.

Carbon dioxide is a quality indicator, signaling whether the subject is taking sufficiently long and deep breaths. Low levels of carbon dioxide suggest shortness of breath. It has also been identified as an indicator of certain infections as well as liver malfunction and excessive bacteria growth. It is also often used as a reference to determine the amount of exhaled air that has been detected by the sensor to help determine the percentage concentrations of constituents.
