A Covid-19 breath test trialled in Dubai earlier this year has been provisionally approved for use in Singapore.
BreFence Go was designed to deliver accurate results within one minute and was developed by start-up Breathonix and scientists at the National University of Singapore.
The device works by having a patient exhale into a disposable one-way valve mouthpiece. It measures and analyses levels of certain biomarkers – volatile organic compounds – that appear when the immune system is fighting disease.
The test is significantly faster than currently available methods, such as the PCR, the results of which can take up to 48 hours to process in local labs.
