The test kits will be used in a new COVID-19 testing lab at Changi Airport. The Health and Science Authority has approved the use of a deep-throat saliva (DTS) COVID-19 testing kit called RESOLUTE 2.0 by Advanced MedTech Holdings (AMTH). According to AMTH, the DTS specimen collection is less invasive and more comfortable than the current collection which involves swabs inserted into the back of the nose and throat because DTS collection only requires patients to draw out saliva from deep within their throat and spit into a specimen bottle. “This makes it easy-to-administer and allows patients to conduct the collection themselves without the supervision of medical professionals, therefore mitigating the risks of potential virus spread as well,” AMTH said.
