Saliva test a 'valid and accurate' alternative to nose/throat PCR swab, RCSI study finds

The less invasive alternative to the nasal and throat swab could allow for greater capacity and frequency of testing for people who require regular screening.

Using saliva to test for Covid-19 has been found to be almost as accurate as the current PCR test of a nose and throat swab.

That is according to the RCSI University of Medicine and Health Sciences, which suggest that the less invasive alternative to the nasal and throat swab could allow for greater capacity and frequency of testing for people who require regular screening.
