Eligible for PCR COVID-19 Testing?

Members of the general public with mild symptoms are asked not to seek PCR testing. Publicly-funded PCR testing is only available for high-risk individuals. Please refer to pages 2-4 of the COVID-19 Provincial Testing Guidance for a list of eligible individuals..

Most individuals with a positive result from a rapid antigen test are no longer required or encouraged to get a confirmatory PCR or rapid molecular test.

If you test positive using a rapid antigen test, it is highly likely you have COVID‑19. You must isolate and determine the next step for others in your household – Step One: Confirm if you need to isolate

Where and When to Get Tested

Anyone eligible for a PCR test under the provincial testing guidelines can get one at no cost. Depending on your situation, you may be able to get a COVID-19 test at:

Some locations may have certain restrictions (for example, some are unable to test young children).

Public Assessment Centres

Public assessment centres can assess, test, and provide treatment options for people who know or suspect they have COVID-19 and who meet certain criteria.

You should visit one if you have symptoms and:

  • are at higher risk for COVID-19 and need to get tested and assessed for treatment (including antiviral treatment)
  • have been directed by your primary care provider

You do not need to have a positive test result to visit. You should bring a list of your medications and a list of any important medical conditions.

If you develop severe symptoms requiring medical attention, such as shortness of breath or chest pain, call 911 or go to the emergency department.

Sarnia-Lambton COVID-19 Assessment Centres Offering Access to COVID-19 Antiviral Treatments

An individual’s risk of serious illness is determined based on a combination of your health, age, and vaccination status, based on an assessment from a health care provider. This includes:

  • Adults 18 years of age and older who are immunocompromised (have an immune system that is weakened by a health condition or medications)
  • Adults 70 years and older with a clinical assessment, regardless of vaccination status
  • Adults 60 years and older who have had fewer than three doses
  • Adults 18 years and older who have had less than three doses and have risk conditions
  • Unvaccinated pregnant individuals

For more information on eligibility, visit Ontario’s COVID-19 antiviral treatment screener.

Note: COVID-19 Antiviral Treatments are not substitutes for vaccines. The best defense against serious COVID-19 disease is to get vaccinated. To book a vaccination, visit GetTheVaccine.ca

High-risk individuals experiencing COVID-19 symptoms can contact their primary care provider to get tested and assessed for treatment right away. Individuals who do not have a primary care provider can book an appointment with a local COVID-19 Assessment Centre (find location here).


If you are not eligible for a test but have symptoms of COVID-19, assume that you have COVID-19 and isolate:

for at least five days if you are:

  • fully vaccinated
  • under 12 years of age

for at least 10 days if you are:

  • over the age of 12 and not fully vaccinated
  • immunocompromised
  • living in a highest risk setting

Rapid Antigen Testing (RAT)

Rapid antigen testing may be used for routine, repeated screening of people with no symptoms to identify and prevent cases of COVID-19 in hospitals, long-term care and retirement homes, and other high-risk settings as an added layer of safety. Rapid antigen testing may also be used to test people with symptoms to find out the likelihood that their symptoms are related to COVID-19.

If you or someone you live with gets a positive result on a rapid antigen test, you must isolate:

  • for at least five days if you are:
  • for at least 10 days if you are:
    • over the age of 12 and not fully vaccinated
    • immunocompromised
    • living in a highest risk setting

A positive result:

  • is a good indication that you have COVID-19
  • usually does not need to be confirmed by a PCR test
  • does not need to be reported to public health

A negative result:

  • on a single test cannot rule out COVID-19 infection by itself
  • if you have symptoms, should be followed by a second test 24 to 48 hours later if available. If your second test taken within 48 hours of your first negative result is also negative, this most likely means you do not have COVID-19 and may come out of isolation when have not had a fever for 24 hours and other symptoms are improving for at least 24 hours (or 48 hours if gastrointestinal symptoms).

If you feel unwell but do not have symptoms of COVID-19, you should isolate until your symptoms have improved for at least 24 hours (or 48 hours if the symptoms affect the digestive system).

Frequently Asked Questions

What Happens AFTER I get a PCR Test?

If you received a negative PCR test result, you need to self-isolate until you have no symptoms for at least 24 hours. If you don’t have symptoms and you have not been told to self-isolate, please continue to self-monitor for symptoms until you receive your results.

View more information about what happens after you get tested.

Can the test tell me if I have ever had COVID-19?

The test can only tell you if you have COVID-19 at the time of the test. The test will not tell you if you had COVID-19 in the past.
