Frequently Asked Questions

What happens after I get the test?

If you have any symptoms, 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 yourself for symptoms until you receive your results.

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.

How will I find out about the test result?

You can use the online portal, and enter your information to receive your test result. If your test result is positive, you will be contacted by Lambton Public Health for follow-up.

What happens if I have symptoms after I get a test result?

You should get retested if you develop symptoms. Please contact the assessment centre to schedule another test.
