Health Canada approves 1st rapid antigen COVID-19 test, feds plan to buy 20 million

Health Canada regulators today approved another rapid COVID-19 test the first antigen device to receive the necessary approvals for use in this country.

U.S.-based Abbott Laboratories can now sell and distributethe Panbio COVID-19 Ag Rapid Test Device, which can produce results in less than 20 minutes.

Public Services and Procurement Minister Anita Anand said today the federal government has signed an agreement to buy more than 20.5 million of these tests in the coming weeks. The devices are to bedeployedto COVID-19 hotspotsas demand for testing spikes andcaseloads grow.

"Cases are on the rise and testing andtracing is more important than ever," Anand said.

The test is advertised as an option for mass testing in "decentralized settings." Health Canada has authorized it as a "point-of-care" test, meaning it can be used by trained professionals in pharmacies, walk-in clinics or doctors' offices.

While the U.S. Food and Drug Administration authorized two antigen testing devices months ago, Health Canada has been reluctant toput its stamp of approval on such tests.

Public health experts and Ontario Premier Doug Ford have been urging the regulators to make more testing options available as the province grapples with hours-long waits at hospital-run testing centres and a backlog of tens of thousands of samples to be tested.

Anand said the antigen tests are not designed to supplantthelab-based testing optionscurrently in use across the country.

In an effort to reduce a testing backlog, Health Canada has approved a rapid antigen test for COVID-19 that produces results in less than 20 minutes. The federal government has ordered more than 20 million of the tests, but theyre believed to be less accurate than others.

"To be clear, the strategy in terms of our procurementsis notto replace the standardized testing model but to enhance the capacity of provinces and territories to keep up with theincreasing demandfor tests. Our strategy is one of diversificationacross various testing types and models," Anand said, adding thatthe government haspurchased enough swabs and reagent to conduct 200,000 conventional molecular tests per day for the remainder of the year.

Anandsaid 8.5 million tests will be distributed across Canada by year's end; the delivery schedule is to be finalized with Abbott in the coming days. Canada has secured options for 12million more tests that could be ordered in the future if the government is satisfied withPanbio's performance.

Intergovernmental Affairs Minister Dominic LeBlancsaid the rapid test purchase would ensure provincescan "carry out more testsmore quickly and cases of COVID-19 will be spotted quicker."

"Everyone with a negative result will be able to go back to work or school as soon as possible," he said in French.

Health Minister Patty Hajdu, whopreviously questioned the accuracy of antigen tests, said the new Abbott device will take pressure off overrun testing sites andoffer specific "advantages"for remote communities whereaccess to laboratory testing is limited.

"They are easier to perform with limited training and can be done at the point-of-carewith generally morerapid results," Hajdu said. "These arevaluable tools for remote or isolated communities or special settings.

"If someone is symptomatic you can rapidly testthem onsite and determine if they need a further PCR test, but it gives assurances in that setting. That will alleviate, in the long-term ... outbreaks and the contact tracing that has to be done."

Conservative MP Michelle Rempel Garner, the party's health critic, said it was "disgusting" ofHajdu to champion a new rapid test on the same day Ontario was sending some of its COVID samples to California because of a laboratory pileup.

Conservative MP Michelle Rempel Garner challenges Health Minister Patty Hajdu on testing efficiency.

"The test they're talking about today won't be in the hands of Canadians until the end of the year. They had months to do this and they failed," she said in question period. "The prime minister has failed to deliver rapid tests. They're not coming anytime soon."

Molecular test approved by Health Canada last week

Health Canada approved another Abbott rapid test last week the ID NOW, which is the molecular test that has been used at U.S. President Donald Trump's White House to screen staff since April.

The government has said 2.5 million such tests will arrive by December 31, 2020.

The Panbiois designed to give "preliminary test results," and, according to Abbott, a negative result "doesn't preclude SARS-CoV-2 infection."

The company warns that such a test "cannot be used as the sole basis for treatment or other management decisions."

The test is already in use in major Western countries such as France, where it is used to quickly identify those who have been infected in airports or hospital reception areas.

The antigen rapid tests which, depending on the device, use matter collected from nasal or throat swabs don't require the use of a lab to generate results.

Tests considered less accurate than PCR

While much faster, these tests are considered to be less accurate than the "gold standard" the polymerase chain reaction (PCR) testing process currently in use across Canada.

If administered properly, PCR tests are highly accurate, identifying positive cases nearly 100 per cent of the time.

Antigen tests, which detect the presence of viral proteins in a biological sample, are also considered highly accurate but they are not as sensitive as molecular PCR tests run through a lab.

Deputy Chief Public Health Officer Dr. Howard Njoo explains how the Panbio COVID-19 test fits into the government's testing strategy.

Preliminary results from a clinical study conducted by Abbott on 241 samples found that the Panbio COVID-19 Ag test has a sensitivity rate of 93.3 per cent in people suspected of having been exposed to COVID-19 or showing symptoms in the past seven days.

(A test with 93.3 per centsensitivity will correctly return a positive result for 93.3 per cent of people who have the diseasebut will return a negative result a false-negative for 6.7 per centof the people who have the disease and should testpositive.)

Dr. Howard Njoo, Canada'sdeputy chief public health officer, said antigen tests are inexpensive and easy to administer and can be regularly deployed at specific workplaces (like meat-packing plants) or in congregant living settings long-term care homes, homeless shelters,prisons orjails to get an immediate read on someone's status.

Someone who receives a positive antigen testcould then be sent for a follow-up PCR test to confirm the result, he said.
