In a Canadian first, Nova Scotia researchers say COVID-19 rapid tests that include both throat and nose swabs provide greater accuracy in detecting the virus.
Up until now, the instructions provided by the manufacture has been for nasal swab only.
Now, based on research led by Nova Scotia Health’s microbiology team, public health is recommending Nova Scotians using rapid tests swab both their throat and nose when collecting their sample.
In a release Friday, Nova Scotia Health said its working to update the current testing instructions that people receive when they pick up a rapid test.
The research was prompted by public discussion theorizing that a combined sample may produce more accurate results.
Speaking to CTV Thursday, Dr. Todd Hatchette, the chief of the province’s Division of Microbiology, Department of Pathology and Laboratory Medicine, said researchers found using a single swab on a person’s throat first, and then in both nostrils is more effective at detecting Omicron than doing either site alone.
“When we tested just over 1,500 people, we found that either the nose or the throat both detected about 60 per cent of people, but if you did a combined nose / throat, it detected over 82 per cent of people,” said Hatchette.
The research started about a week ago. Officials at the microbiology lab worked with volunteers at the Halifax Convention Centre testing site to collect the data.
In Friday’s release, Nova Scotia Health says collaboration with volunteer-based community rapid testing sites was key to the project’s success and allowed the project to rapidly answer a question that many jurisdictions across the country have been asking.
The investigation compared results of a common rapid take-home test using three sample sites: nasal swab; throat swab and; combined nasal/throat, the release said. All results were confirmed with PCR testing. Compared to PCR test results, samples from nasal or throat swabs each detected 64.5 per cent of cases; however, combining the nose and throat swabs increased sensitivity to 88.7 per cent.
This research project has been submitted for publication.
Dr. Theresa Tam, Canada’s chief public health officer, speaking Friday from Ottawa, welcomed the Nova Scotia swab study.
“I’ve asked our laboratory network, our laboratory experts, to take that into account and see whether we can provide some sort of guidance,” Tam said. “But, of course, I think we’ve been discovering that the Omicron variant may be behaving a bit differently to the previous variants, so this approach, this swabbing, might be useful.”
One thing to note, public health is advising that if only one location of the sample is being used, it should be the nasal swab, as the throat swab alone is not as effective as the nasal swab.
Nova Scotia is the first to report research results supporting a combined throat/nose collection method for self-administered rapid antigen tests.
CALGARY – TC Energy Corp. has lowered the estimated cost of its Southeast Gateway pipeline project in Mexico.
It says it now expects the project to cost between US$3.9 billion and US$4.1 billion compared with its original estimate of US$4.5 billion.
The change came as the company reported a third-quarter profit attributable to common shareholders of C$1.46 billion or $1.40 per share compared with a loss of C$197 million or 19 cents per share in the same quarter last year.
Revenue for the quarter ended Sept. 30 totalled C$4.08 billion, up from C$3.94 billion in the third quarter of 2023.
TC Energy says its comparable earnings for its latest quarter amounted to C$1.03 per share compared with C$1.00 per share a year earlier.
The average analyst estimate had been for a profit of 95 cents per share, according to LSEG Data & Analytics.

BCE Inc. reported a loss in its latest quarter as it recorded $2.11 billion in asset impairment charges, mainly related to Bell Media’s TV and radio properties.
The company says its net loss attributable to common shareholders amounted to $1.24 billion or $1.36 per share for the quarter ended Sept. 30 compared with a profit of $640 million or 70 cents per share a year earlier.
On an adjusted basis, BCE says it earned 75 cents per share in its latest quarter compared with an adjusted profit of 81 cents per share in the same quarter last year.
“Bell’s results for the third quarter demonstrate that we are disciplined in our pursuit of profitable growth in an intensely competitive environment,” BCE chief executive Mirko Bibic said in a statement.
“Our focus this quarter, and throughout 2024, has been to attract higher-margin subscribers and reduce costs to help offset short-term revenue impacts from sustained competitive pricing pressures, slow economic growth and a media advertising market that is in transition.”
Operating revenue for the quarter totalled $5.97 billion, down from $6.08 billion in its third quarter of 2023.
BCE also said it now expects its revenue for 2024 to fall about 1.5 per cent compared with earlier guidance for an increase of zero to four per cent.
The company says the change comes as it faces lower-than-anticipated wireless product revenue and sustained pressure on wireless prices.
BCE added 33,111 net postpaid mobile phone subscribers, down 76.8 per cent from the same period last year, which was the company’s second-best performance on the metric since 2010.
It says the drop was driven by higher customer churn — a measure of subscribers who cancelled their service — amid greater competitive activity and promotional offer intensity. BCE’s monthly churn rate for the category was 1.28 per cent, up from 1.1 per cent during its previous third quarter.
The company also saw 11.6 per cent fewer gross subscriber activations “due to more targeted promotional offers and mobile device discounting compared to last year.”
Bell’s wireless mobile phone average revenue per user was $58.26, down 3.4 per cent from $60.28 in the third quarter of the prior year.

TORONTO – Canada Goose Holdings Inc. trimmed its financial guidance as it reported its second-quarter revenue fell compared with a year ago.
The luxury clothing company says revenue for the quarter ended Sept. 29 totalled $267.8 million, down from $281.1 million in the same quarter last year.
Net income attributable to shareholders amounted to $5.4 million or six cents per diluted share, up from $3.9 million or four cents per diluted share a year earlier.
On an adjusted basis, Canada Goose says it earned five cents per diluted share in its latest quarter compared with an adjusted profit of 16 cents per diluted share a year earlier.
In its outlook, Canada Goose says it now expects total revenue for its full financial year to show a low-single-digit percentage decrease to low-single-digit percentage increase compared with earlier guidance for a low-single-digit increase.
It also says it now expects its adjusted net income per diluted share to show a mid-single-digit percentage increase compared with earlier guidance for a percentage increase in the mid-teens.
