SARS-CoV-2 still has the world in its grasp with soaring infection numbers throughout Europe and the US. A quick, non-invasive test to detect Corona disease would be a tremendous game changer in combatting this pandemic. This might become reality soon: a Singapore start-up has developed a real-time COVID-19 breath test based on our PTR-TOFMS trace gas analyzers. Breathonix, a spin-off from the prestigious NUS (National University of Singapore), combines our PTR-TOF analyzer with their own machine learning software.

Their non-invasive COVID-19 test takes less than one minute and has been on a pilot clinical trial together with the National Centre for Infectious Diseases involving 180 patients. The results are promising, achieving 90% accuracy with 93% sensitivity.

Dr. Jia Zhunan, Breathonix CEO, explains: “93% of sensitivity means that using the biomarkers we identified, we are able to correctly classify 93 patients as positive among 100 positive patients, 95% specificity means we are able to correctly identify 95 patients as negative among 100 negative ones.”

We support Breathonix’ vision with expert advice, derived in many breath gas research projects, OEM PTR-TOF trace gas analyzers and breath sampling solutions. It is our mission to contribute to our customers endeavors to advance the frontiers of science.
