Breath tests, simple yet revolutionary diagnostic tools, have transformed how we detect diseases. Modern breath testing could trace its root back to the pioneering research on gas metabolism conducted by French chemist Antoine Lavoisier in the 18th century. Over two centuries of development, breath tests have blossomed from basic scientific curiosities into highly sophisticated diagnostic methods, becoming the the go-to choice for non-invasive diagnosis.

From humble origins in gas metabolism studies to today’s front-line diagnostics, breath tests are quietly reshaping healthcare—delivering speed, patient comfort, and healthcare accessibility with every exhale.
