Why in news?

  • A breath test designed to detect Covid-19 and give accurate results within a minute has been approved for use in Singapore.

About the test:

  • The test was developed by National University of Singapore based startup Breathonix.
  • It works much like a standard breathalyzer test; a person blows into a one-way valve mouthpiece, and compounds in the person’s breath are compared by machine learning software against the sort of breath signature that would be expected from someone who is Covid-positive.
  • Singapore will screen incoming travelers from Malaysia at the Tuas Checkpoint on the western side of the island in a deployment trial of the breathalyzers.
  • Anyone who tests positive in the breath test would be screened in a confirmatory PCR swab test.
  • The Breathonix test has so far undergone three clinical trials, and has achieved a sensitivity of 93 per cent and specificity of 95 per cent in one.
