How the SD Biosensor works

You can follow these steps to administer your SD Biosensor rapid antigen COVID-19 test, but be sure to reference the detailed instructions included in your test kit.

  1. Open your sample tube. Open the package that includes your sample tube, which comes prefilled with buffer liquid, and stand the tube upright.
  2. Collect your sample. Remove the swab from the package and follow the instructions for how to take a sample from each nostril.
  3. Prepare your sample. Put your swab in the prepared tube and press it against the sides to release your sample.
  4. Test your sample. Press the nozzle cap on the tube and add 4 drops of sample onto your test card. Read the results in 15 minutes.
  5. Interpret your results. Consult the test card panel to find out if your results are positive, negative or invalid according to the legend below.

What’s included in the SD Biosensor COVID test

How SD Biosensor compares to other at-home tests

SD Biosensor tests compare well with other rapid antigen tests on the market.

  • Accuracy. These tests have a high sensitivity rating of 97.12%, which means that they will detect an accurate positive result in over 97% of COVID-19 patients.
  • Cost. SD Biosensor COVID-19 tests are more expensive than many other COVID-19 rapid antigen tests (by about $3 to $6 per test). You can also only buy them in packs of 25, so they may not be ideal if you only need a few tests.
  • Speed of results. SD Biosensor is on par with other rapid antigen tests for speed, with results displaying in around 15 minutes.

What does Health Canada say about SD Biosensor COVID-19 tests?

Health Canada approved SD Biosensor tests in Canada in February 2021. These tests are intended for use by medical professionals and should only be used in conjunction with PCR or molecular testing to validate a positive or negative COVID-19 result.

Some countries accept rapid antigen tests such as SD Biosensor tests for travel if they are validated by a telehealth agent, lab technician or doctor. You’ll need to check what type of test your destination country will accept before you leave for your trip.

What to do if you test positive

The guidelines for how to deal with a positive COVID test result in Canada are constantly changing. Your best bet is to ask your doctor or local health authority what steps to take if you test positive.

As a baseline, you’ll usually need to self-isolate at home for 10 days from the onset of symptoms and let your close contacts know that you’ve tested positive.

About at-home COVID rapid tests

Rapid antigen tests are used to detect a specific type of molecule in your sample that’s linked to COVID-19. If the molecule is present, then the test will show a positive result in under 15 minutes. These results should be fairly accurate as long as the test is carried out properly.

Rapid tests are often ineligible as proof of COVID-19 results for travel. However, they may be eligible in a select number of countries if your results are validated by a medical professional.

Can I get a free at-home COVID test?

Many provinces offer free at-home COVID tests through the public health authority, but you may need to display symptoms to get one. You can easily find out about test availability near you by searching the name of your city followed by “where to get tested for COVID-19” or “free rapid antigen tests” in Google.
