Breath AI

Breath AI

This solution delivers a non-invasive, breath-based diagnostic platform that combines Proton Transfer Reaction Mass Spectrometry (PTR-MS) with explainable AI to enable rapid, affordable early detection of multiple diseases such as lung cancer, tuberculosis and chronic metabolic diseases. The system analyzes volatile organic compounds in exhaled breath to detect disease-specific metabolic “fingerprints” within minutes, supporting point-of-care use in busy and resource-constrained clinics. Its AI engine is purpose-built for clinical PTR-MS data, with robust pre-processing for cross-site consistency, biologically grounded explanations that link predicted risk to metabolic pathways, and an uncertainty mechanism that flags low-confidence cases to protect patients. By replacing invasive, slow or expensive tests with a fast, painless breath check, the platform expands access to screening for vulnerable and ageing populations, reduces diagnostic delays, and empowers healthcare providers to intervene earlier, ultimately improving outcomes and equity in respiratory and chronic disease care.
