PUTRAJAYA (Feb 18): Deep throat saliva samples will soon be used by some government hospitals for Covid-19 tests, said Health Minister Datuk Seri Adham Baba.

He said that on an evaluation by the Institute for Medical Research (IMR), deep throat saliva had a sensitivity of 96.67% and 100% specificity.

In addition, the sampling method is safe and non-invasive compared to sampling with the "nasopharyngeal" and the ‘oropharyngeal’ swab through the nose and mouth, he said.

“The Ministry of Health (MoH) has received approval in principle from the IMR to use the saliva sampling method at government hospitals first.

"Sampling of Covid-19 through saliva will also speed up and increases Covid-19 screenings," he told reporters after receiving 2.7 million low dead-volume syringes, worth RM891,000, from Etiqa Family Takaful Bhd at his ministry here today.

Dr Adham said the sampling method using saliva is self-collected and this is expected to save on the use of personal protective equipment (PPE).

"Patients will be asked to remove their own saliva into a specimen cup and the cup will then be sent to the laboratory for testing," he added.

He said the saliva sampling method is also suitable for the Covid-19 real-time reverse transcriptase-PCR (RT-PCR) test.

"Currently, the IMR is completing a study on the use of saliva samples for RTK antigen (RTK Ag) tests," he said, adding that sampling through the nose and mouth is still used to detect Covid-19.

He said the use of saliva samples for the Covid-19 test had been conducted in several countries and proven to be cheaper and one of the most consistent sample collection methods.
