On the same day Alberta announced it has received results from serology testing conducted in early June, the province also recorded 113 new cases of COVID-19 and five new deaths.
Amid a climbing number of active cases in the province, Alberta’s chief medical officer of health announced some good news Thursday, sharing results from the $10-million targeted serology testing programs.
The testing works to detect the presence of antibodies in a person’s blood, which will indicate if the person has previously been exposed to COVID-19.
“Our labs have analyzed nearly 9,400 anonymous randomized samples from blood tests that were collected for other clinical reasons during the first week in June,” Dr. Deena Hinshaw said in a news conference.
“This provides a baseline estimate of how many Albertans had antibodies to the COVID-19 virus at that point in time, reflecting infections that would have happened before the middle of May,” she said.
“Of the samples from early June, less than one per cent showed the presence of antibodies.”
Hinshaw said the percentage from the serology testing was applied to the province’s population to conclude that an estimated 36,000 Albertans had been infected with COVID-19 as of May 20.
“We had identified just over 6,000 cases with swab testing,” she added.
“This indicated that Alberta’s testing program had identified about 17 per cent of cases in the population.”
Hinshaw noted that number is more successful than other jurisdictions, not only in Canada but across the globe.
“I think it’s very encouraging,” she said.
Hinshaw said further analysis of June’s serology testing data and upcoming data from July will be used to help inform the province’s response to the ongoing pandemic.
Hinshaw also announced changes to accessing coronavirus testing in the province, noting all pharmacies will now be able to provide testing if they wish to do so and if they can fulfill safety requirements.
She added there is a process the pharmacies must first go through which enables them to offer these tests and it may take several weeks for them to get up and running in communities across Alberta. Only residents who are not exhibiting any symptoms or who have not been knowingly exposed to the virus can be tested at pharmacies, Hinshaw said.
“Many people are excited to access testing closer to home and many pharmacies are excited to offer this critical service,” Hinshaw said.
Hinshaw said the province is also working to decrease wait times in Alberta to access testing. She said more staff are being hired in the fall to conduct these tests and testing hours are also being expanded across the province.
