Which test when?

CAFN distributes 3 types rapid COVID-19 tests to Citizens and employees:

Rapid Antigen Tests:

  1. BTNX
  2. Abbott PanBIO

Molecular Test:

  1. Lucira “Check-it” test

Both types of test are designed to detect whether someone has an active COVID-19 infection. However, the way they work is different. Molecular tests, like Lucira, are more sensitive and can detect when SARS-CoV-2 virus is present at significantly lower viral levels. Antigen-based tests detect specific proteins on the surface of the virus.

Use the rapid antigen tests for screening if you have or do not have symptoms.

Use the molecular (Lucira) test if you have symptoms.

Which test to use when?

  • Use the rapid antigen tests (BTNX or Abbott PanBIO) tests for asymptomatic or symptomatic screening.
  • Use the Lucira test if you have symptoms, but test “negative” on a rapid antigen test, especially when you’ve had a known exposure to COVID-19.

Please note: the Lucira test is a rapid molecular test and can find very small amounts of COVID-19 in your system many weeks after an infection. Don’t use the Lucira test if you know that you’ve been positive for COVID-19 within the last 90 days.

The Lucira tests that CAFN is currently using have an extended expiry date. Add nine months to the original expiry date printed on your box.
