DSA BreathPass™

Intended use

DSA BreathPass™ is a handheld device used by healthcare professionals and intended for non-intrusive, rapid screening of large numbers of people to provide presumptive negative results of COVID-19 infection.

 Inside the device there is an array of nano-sensors to detect molecules of biological origin, known as volatile organic compounds (VOC), as signs of infection stemming from the biomarkers known to be produced by the metabolic processes caused by the SARS-CoV-2 virus.

Testing principle

The DSA BreathPass^TM uses a non-invasive method for indication of COVID-19 caused by the SARS-CoV-2 coronavirus. The device measures the exhaled breath for 45 seconds, characterizes the VOCs within breath samples, produces indications for different health conditions based on Deep Computing algorithms and generates results in few seconds.

The DSA BreathPass^TM is a fast, easy and affordable testing method for screening large populations anywhere with a reliable connection to the internet.

The DSA BreathPass^TM is used via the BreathPass Mobile Application which is available at both Google Play and App Store. User credentials are needed for the APP download and use.  BreathPass mobile APP is available in the App Store in only those countries where the underlying DSA BreathPass™ device is approved for use.
