Who should do a rapid antigen test

  • People with symptoms
  • Household, social, workplace or education contact of a positive case
  • Anyone before going to an event with lots of others, or before visiting vulnerable family members
  • Anyone arriving from overseas (passengers and flight crew)

What happens if I get a positive rapid antigen test result?

If you test positive on a rapid antigen test you most likely have COVID:

Test result SymptomsExposure riskNext step
Yes Yes Known or unknown contactYou are a confirmed case, follow the advice for people testing positive for COVID-19
Yes Yesor NoKnown high risk or household contactYou are a confirmed case, follow the advice for people testing positive for COVID-19
Yes No No known contactYou may be a case, take another rapid antigen test in 24 hours or have a PCR test

What happens if I get a negative rapid antigen test result?

If you are a household contact or had a high-risk exposure to someone with COVID then you must continue to isolate for 7 days. You must follow the advice for people exposed to COVID-19 to determine your risk. To determine if you are a high risk exposure use the Information for people exposed to COVID-19 and follow the relevant isolation advice.

If you have symptoms please take another rapid antigen test in 24 hours or have a PCR test. If your second test is positive you are considered a confirmed case. If the second test is negative, you should isolate until your symptoms have gone.

Who should have a PCR test?

You should do a PCR test if:

  • you have COVID-19 symptoms, but have tested negative on a rapid antigen test AND are at higher risk of severe disease including those who are pregnant, immunosuppressed, Aboriginal and Torres Strait Islander, Pacific Islander, or unvaccinated
  • you have symptoms and can’t get a rapid antigen test
  • you have been asked to have a PCR test from a health care provider.

If I have tested positive, what do I do?

Follow the advice for people testing positive for COVID-19.
