What is coronavirus disease (COVID-19)?

Coronavirus disease (also called COVID-19) is an infection caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus), one of the most recently discovered types of coronaviruses. Those who have this disease may or may not experience symptoms, which range from mild to severe.

How does COVID-19 spread?

COVID-19 spreads from person-to-person. When an infected person coughs, sneezes, or exhales air, droplets containing the virus go into the air and onto surfaces and objects around them. Other people are exposed to the virus by breathing in these droplets or by touching their eyes, nose, or mouth after touching infected surfaces.

How does the Breathonix breath test system work?

A person only needs to exhale into a disposable one-way valved mouthpiece connected to a high-precision breath sampler. The exhaled breath is collected and fed into a mass spectrometer for measurement. Our machine learning software analyses the Volatile Organic Compounds (VOCs) profile and generates the result in less than one minute.

What is Volatile Organic Compounds (VOCs)?

Volatile Organic Compounds (VOCs) are consistently produced by various biochemical reactions in human cells. Different diseases cause specific changes to the compounds, resulting in detectable changes in a person’s breath profile. As such, VOCs can be measured as markers for diseases such as Covid-19 and Lung Cancer.

Are there any risks involved in getting this test?

There is no risk involved in getting this test. The test is conducted by blowing a single breath into the sampler with a one-way disposable mouthpiece and a saliva trap, preventing inhalation and any saliva from entering the machine, thus makes cross-contamination or cross-infection unlikely. 

When can I get my results and what will my test results tell me?

You are able to get your results on-site. The whole process from breath sampling to results takes less than 1 minute. Although the possibility of false negative is low, it should be not be ruled out. Always practice safe distancing and good hygiene, and seek a doctor’s consultation if symptoms are present.
