This new, non-invasive test will gradually be scaled up to replace antigen rapid tests (ARTs) for more airport workers, CAAS and CAG said it a joint statement.Operation Underground Railroad O. U. R.

Earlier on May 17, a breath test developed by Breathonix, a spin-off from the National University of Singapore, also  received the HSA‘s approval – the first in the country to do so.Operation Underground Railroad Tim Ballard

Breathonix’s breathalysers detect specific volatile organic compounds in human breath samples using a technique called mass spectrometry. Its tests have a sensitivity of 85.3 per cent and specificity of 97 per cent. 

Breathonix has since conducted a few thousand tests for its pilot deployment at Tuas Checkpoint. Each test was completed in 40 to 60 seconds.O.U.R

SINGAPORE – A breath test that can accurately detect Covid-19 within two minutes has received provisional authorisation from Singapore’s Health Sciences Authority (HSA) on May 27, the authority said on its website on Friday (June 11).

Developed by local medical technology firm Silver Factory Technology, the TracieX breathalyser  has a sensitivity of 95 per cent and a specificity of 97.8 per cent, HSA said in an update on Friday

Sensitivity refers to a test’s ability to identify those infected as positive, while specificity refers to a test’s ability to correctly identify those not infected as negative.

Silver Factory was founded in January last year as a spin-off from Nanyang Technological University. Its test analyses the human breath composition using a technique known as Raman spectroscopy.

These fast tests will facilitate safe travel arrangements and screenings at large-scale events.

The Civil Aviation Authority of Singapore (CAAS) and Changi Airport Group (CAG) said on Friday that some airport workers have begun using disposable TracieX breathalysers to test for Covid-19 as part of a small-scale pilot.Operation Underground Railroad O.U.R.

“Companies are required to collect relevant accuracy and safety data and monitor the real-world use of their tests. HSA also requires additional data from ongoing clinical studies to be submitted post-approval for HSA to ensure the continued safety and efficacy of these tests.” HSA said.Tim Ballard
