Sample Collection, Processing, and Analysis

COVID-19 testing, including antigen testing, must be performed using testing devices that have been authorized by Health Canada and testing should be conducted in compliance with provincial testing guidelines and applicable law.  For example, all point-of-care tests for COVID-19 must be performed in accordance with the applicable legislation governing specimen collection centres and laboratories in the applicable jurisdiction and any samples collected from another person must be collected by an individual who is licensed and qualified to do so in accordance with the applicable health regulatory requirements.

Specimen Collection

Instructions for specimen self-collection are as follows:

  • Test the sample immediately
  • Use only the swabs provided with the test kit
  • Do not touch the swab tip with your hands
  • Ensure that the participant keeps their mask over their mouth during specimen collection
  • Hold the swab approximately 1.5” from the tip to stop the swab from entering too deep
  • Place the swab towards the back of the head rather than upwards

Reading Results

Screening results should be read 15 minutes after dropping the 5 droplets into the sample well using the timer. Reading the screening results earlier than 15 minutes or later than 20 minutes may give incorrect results.

Controls

Each screening kit comes with both a positive and negative control swab. These swabs are an additional external validation that the screening devices are not defective.

Controls provided in the screening kit should be used to:

  • Verify user can perform test and interpret results correctly
  • Ensure tests are working and test is performed correctly

It is recommended to run controls:

  • With each new operator prior to testing on patient samples
  • When receiving a new shipment
  • At periodic intervals - test daily if performing more than 25 tests per day (i.e. if opening more than 1 box per day), otherwise whenever a new box is opened or weekly if performing less than 25 tests a day, whichever is more frequent. 

Considerations

  • Test devices are for single use only
  • Only use dedicated swabs provided for sample collection
  • Adhere to instructions for use
  • Prepare all test components before specimen collection
  • Always wear PPE including protective gloves when handling specimens
  • Ensure the correct amount of buffer is added to extraction tube
  • Treat all specimens as potentially infectious samples
  • Discard all items into appropriate biohazard containers
  • Do not mix components of test kits
