Saliva screening is as effective as nasal swabs when it comes to testing for Covid-19, researchers at a university in the UAE have found.
The study, published the peer-reviewed journal Infection and Drug Resistance, found testing for the virus using saliva is equally as accurate as the widely used PCR tests, which require a more invasive and uncomfortable nasal swab.
The findings could change the way people are screened and increase testing capacity, as a saliva sample could be self-administered without the help of medical staff.
This would also reduce potential exposure of staff to the virus and minimise the amount of medical equipment used.
With everyone looking for easy alternatives, our study shows how the adoption of saliva as specimen for Covid-19 testing can decrease the strain on healthcare resources
A team from Mohammed Bin Rashid University of Medicine and Health Sciences took saliva and nasal swabs from 401 adults who had attended Khawaneej Health Centre for a Covid-19 test. Half of the sample size were asymptomatic.
The samples were tested for detection of Sars-CoV-2, the virus that causes Covid-19, at Unilabs Dubai.
The findings of the study showed that the saliva can be used for viral detection with 70 per cent sensitivity and 95 per cent specificity, proving to be just as effective as the nasal swab.
Studies have suggested that coronavirus initially binds to cells in the body’s nasal cavity and then begins replicating, spreading through the body’s respiratory tract. The virus is understood to then spread to the body’s oral cavity. Previously, it was questioned whether there would be enough virus to be spotted easily with a saliva test. The UAE study, among others, indicates that it is possible.
Patients collected specimens of their own saliva in sterile containers. No preservative was needed while they were being taken to the laboratory.
“This study has shown good diagnostic accuracy for saliva and the feasibility for its utilisation as a potential specimen of choice in community settings and population-based screening,” said Prof Abiola Senok, lead investigator of the study and professor of microbiology and infectious diseases at the College of Medicine at MBRU.
Co-author Dr Hanan AlSuwaidi said saliva testing would reduce strain on critical health equipment, eliminate the need for preservatives and be a more cost-efficient method of mass testing.
“With everyone looking for easy alternatives to nasopharyngeal swab, our study shows how the adoption of saliva as specimen for Covid-19 testing can decrease the strain on healthcare resources,” she said.
“For the current nasopharyngeal swab, staff need to wear personal protective equipment when taking the samples from the patients. With saliva the patients collect their own samples, therefore PPE resources can be freed up for use elsewhere.”
The research team from MBRU was joined by teams from Dubai Health Authority, Unilabs, Cleveland Clinic Abu Dhabi; NYU Abu Dhabi and the National Reference Laboratory.
The study was one of the first research projects to receive approval from the Emirates Institutional Review Board for Covid-19 Research.
Several Covid-19 tests are currently available across the UAE.
These include the standard nasal swab PCR test, the Dh50 laser DPI test, which scans the blood for signs the body is fighting a virus, the LamPORE test, designed to test both saliva and swab RNA samples, and a serology test, which scans for Covid-19 antibodies and can tell if someone has had the virus and has any immunity to it.
Terror attacks in Paris, November 13, 2015
- At 9.16pm, three suicide attackers killed one person outside the Atade de France during a foootball match between France and Germany
- At 9.25pm, three attackers opened fire on restaurants and cafes over 20 minutes, killing 39 people
- Shortly after 9.40pm, three other attackers launched a three-hour raid on the Bataclan, in which 1,500 people had gathered to watch a rock concert. In total, 90 people were killed
- Salah Abdeslam, the only survivor of the terrorists, did not directly participate in the attacks, thought to be due to a technical glitch in his suicide vest
- He fled to Belgium and was involved in attacks on Brussels in March 2016. He is serving a life sentence in France

Sheikh Tahnoon bin Shakhbut (ruled 1818-1833) Expanded Qasr Al Hosn further as Abu Dhabi grew from a small village of palm huts to a town of more than 5,000 inhabitants.
Sheikh Khalifa bin Shakhbut (ruled 1833-1845) Repaired and fortified the fort.
Sheikh Saeed bin Tahnoon (ruled 1845-1855) Turned Qasr Al Hosn into a strong two-storied structure.
Sheikh Zayed bin Khalifa (ruled 1855-1909) Expanded Qasr Al Hosn further to reflect the emirate's increasing prominence.
Sheikh Shakhbut bin Sultan (ruled 1928-1966) Renovated and enlarged Qasr Al Hosn, adding a decorative arch and two new villas.

When Umm Kulthum performed in Abu Dhabi
Known as The Lady of Arabic Song, Umm Kulthum performed in Abu Dhabi on November 28, 1971, as part of celebrations for the fifth anniversary of the accession of Sheikh Zayed bin Sultan Al Nahyan as Ruler of Abu Dhabi. A concert hall was constructed for the event on land that is now Al Nahyan Stadium, behind Al Wahda Mall. The audience were treated to many of Kulthum's most well-known songs as part of the sold-out show, including Aghadan Alqak and Enta Omri.

Day 2, Dubai Test: At a glance
Moment of the day Pakistan’s effort in the field had hints of shambles about it. The wheels were officially off when Wahab Riaz lost his run up and aborted the delivery four times in a row. He re-measured his run, jogged in for two practice goes. Then, when he was finally ready to go, he bailed out again. It was a total cringefest.
Stat of the day – 139.5 Yasir Shah has bowled 139.5 overs in three innings so far in this Test series. Judged by his returns, the workload has not withered him. He has 14 wickets so far, and became history’s first spinner to take five-wickets in an innings in five consecutive Tests. Not bad for someone whose fitness was in question before the series.
The verdict Stranger things have happened, but it is going to take something extraordinary for Pakistan to keep their undefeated record in Test series in the UAE in tact from this position. At least Shan Masood and Sami Aslam have made a positive start to the salvage effort.
