BreFence™ Go COVID-19 Breath Test System
Rapid breath test for Covid-19 screening
Despite positive news of vaccines, screening is still necessary to control the pandemic. Our breath test system will provide rapid, non-invasive and affordable solution for mass screening.
Ongoing clinical trials
Initial clinical trial with National Centre for Infectious Diseases (NCID) of Singapore has shown promising results of over 90% accuracy. We are currently ongoing additional trials to further improve our algorithm and are seeking regulatory approval.
Total turnaround time from breath sampling to results takes less than 60 seconds.
Initial clinical trial with the National Centre for Infectious Diseases of Singapore has shown promising results of 93% sensitivity and 95% specificity with machine learning.
Each breath test is significantly more affordable than a PCR swab test and does not require a trained healthcare professional to operate.
How it works
1. SAMPLE BREATH
Instruct user to exhale into a disposable one-way valve mouthpiece,
2. REAL-TIME ANALYSIS
The BreFence™ Go Breath Test System measures and analyses VOCs biomarkers in the breath.
3. INSTANT RESULTS
Obtain the results in 60 seconds with just 3 clicks
– Start, Stop and Send.
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.
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.
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.
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.
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.
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.
