Rapid (at-Home) Tests • How the Tests Work • Where to Get a Rapid Test • Types of Rapid Tests • Rapid Test Results
At-home rapid tests (often called rapid antigen tests) can be used to determine if you have COVID-19 when you have cold or flu-like symptoms. (See When do I need to perform a test?)
You can perform the test yourself at home and the results are ready in less than 20 minutes, depending on the brand of test you use.
At-home rapid antigen tests can be used to support early diagnosis of COVID-19 and to detect growing clusters in communities. Remember, the best protection against COVID-19 remains vaccination and following public health guidelines (e.g., physical distancing, mask wearing, hygiene measures, small gatherings, etc.).
At-home rapid tests are used in BC only for individuals who have COVID-19 symptoms. (See When do I need to perform a test?)
Rapid tests are done by using a swab to collect a sample from each nostril. The swab will only go a few centimeters inside your nose. It should not hurt.
Rapid tests check for protein fragments specific to the COVID-19 virus. Rapid tests are very good at detecting the COVID-19 virus when testing is done between 24 hours to five days after the start of symptoms. This is when virus levels in the body are at the highest.
Rapid tests are not used for asymptomatic screening because they do not reliably detect infections in people who do not have cold or flu-like symptoms.
Remember: Seek medical care if you feel you need it, whether you test positive or negative
Rapid tests for at-home use are going to people who live or work in settings with a higher risk of COVID-19 infection and transmission. These include long-term care facilities, health-care workers, and rural, remote and Indigenous communities where access to health care is limited.
The FNHA is working with provincial and community partners to distribute rapid test kits in First Nations communities to complement rapid testing facilities already in place in some communities. Distribution of kits has already begun. Check with your local health centre.
The FNHA is distributing three brands of rapid COVID-19 tests initially: Lucira, BTNX and Artron. Each kit comes with written instructions.
Written instructions from the BC Centre for Disease Control are also available for some brands, as are video guidelines from the manufacturers:
Regional Health Authorities and other organizations that serve First Nations people may be distributing different brands of test kits.
If your result is negative, it means the COVID-19 virus was not detected at the time the test was taken. This could be because there was not enough virus in your body for the swab to pick it up or that you do not have the virus. It is still possible that you have COVID-19. If you test negative but continue to have cold or flu-like symptoms, the FNHA recommends you test again in 24 to 48 hours.
Even if the test is negative, it is important to self-isolate until your symptoms improve and you feel well enough to return to regular activities. Symptoms might be from other respiratory illnesses that can also make others sick.
If you are a close contact of someone who has COVID-19, you still need to self-isolate for 10 days from the day you had contact with that person unless you are fully vaccinated or had COVID-19 within the last 90 days.
If your result is positive, it means COVID-19 was detected. You very likely have COVID-19 and could pass it on to others.
See I Have COVID-19 for more about these actions.
If your test is not valid:
If you have two invalid test results, get a COVID-19 test at a testing location. Find a Health Authority testing location. If you are served by a First Nations health centre, check to see if testing is available there.
