Covid-19 breathalysers could be used on large scale in Singapore soon
Compared with PCR tests - the gold standard for testing - the disposable breathalyser's sensitivity rate so far has been over 95 per cent, and its specificity, more than 99 per cent. It is also cheaper, costing around US$20 (S$26) each currently. Trials have already started in NCID, Changi Airport Terminal 1 and Certis, with more than 400 individuals tested to date. Silver Factory's breathalyser, TracieX, has been shown to be almost as accurate as polymerase chain reaction (PCR) tests, while taking a fraction of the time - at two minutes - to turn in results.
