Rapid Antigen Test Kit


In an effort to help slow the spread of COVID-19, reduce absenteeism, and to continue to support our school communities, the Toronto Catholic District School Board (TCDSB) is pleased to offer rapid antigen test kits for symptomatic students and staff. 


In alignment with the updated testing guidance from Ontario’s Chief Medical Officer of Health, individuals may use rapid antigen tests if they are experiencing symptoms compatible with COVID-19. 


This testing option is voluntary for students, children and staff. If a symptomatic individual chooses not to participate, they are presumed positive and should isolate immediately and follow updated testing guidance.


The test kit​ contains two rapid antigen tests and is expected to be available to students and staff at their school/work sites beginning the week of January 24, 2022, pending supply.


When to Use a Take-Home Rapid Antigen Screening Kit


For individuals choosing to participate in this testing option, they must display symptoms commonly associated with COVID-19. As outlined in the updated guidance, this includes:


  • Fever and/or chills; OR
  • Cough; OR 
  • Shortness of breath; OR
  • Decrease or loss of taste or smell; OR 
  • Two or more of:
            • Runny nose/nasal congestion
            • Headache
            • Extreme fatigue
            • Sore throat
            • Muscle aches/joint pain
            • Gastrointestinal symptoms (i.e. vomiting or diarrhea)

Symptomatic individuals must complete the rapid antigen tests at home.

There are 3 different varieties of rapid antigen tests that are being distributed by the province. Here are the instructions on how to use each variety:

Parents or guardians may choose to administer this screening on children who may need help (i.e. younger children). 

What to do After Your Test


You will know the outcome of the test within 15 minutes.

Positive Result


If the first rapid antigen test is positive, there is no need to use the second test. A positive rapid antigen test is highly indicative that the individual has COVID-19.

Fully Vaccinated or 11 Years of Age or Younger
If the individual who tests positive is fully vaccinated or 11 years of age or younger, they must self-isolate for at least 5 days from symptom onset and until their symptoms have been improving for 24 hours (or 48 hours if gastrointestinal symptoms), whichever is longer in duration.

Partially Vaccinated or Unvaccinated and 12 Years of Age or Older
If the individual who tests positive is 12 years of age or older and is either partially vaccinated or unvaccinated they must self-isolate for 10 days from symptom onset or from the date of their test (whichever was earlier).

Immune Compromised
If the individual who tests positive is immune compromised (regardless of age and vaccination status) they must self-isolate for 10 days from the onset of symptoms, or from the date of their test (whichever came sooner). 

If symptoms persist / worsen, individuals are encouraged to seek advice from Telehealth​ or their health care provider. 

Please note: in alignment with the updated testing guidance, there is no confirmatory PCR test required if an individual tests positive. For more information about what to do if you receive positive test results, please follow this guidance​

Negative Result


If the first rapid antigen test is negative, complete the second test within 24-48 hours of the first test. If two consecutive rapid antigen tests, separated by 24-48 hours, are both negative, the symptomatic individual is less likely to have COVID-19 infection, and the individual should isolate until symptoms are improving for at least 24 hours (or 48 hours if gastrointestinal symptoms are present).
