I was thinking the same thing regarding accuracy..
Bit inconvenient, if you need to wait around a few hours for a PCR test, after testing positive to the breathalyser test..
Any individual with a positive breathalyser result will need to undergo a confirmatory PCR swab test.
Antigen rapid tests produce results in around 30 minutes and can be done on site. Meanwhile, polymerase chain reaction (PCR) tests, considered to be the gold standard for testing, take a few hours. Swabs for PCR tests also have to be transported to labs.
Where did you get their PPV and NPV figures from?
Sounds like false positives must be reasonably high, to be requiring a PCR test for confirmation, although that could just be the way the Singaporeans like to do it..
Take no chances..
Nothing wrong with competition.
It's a big pie..
