Frequently Asked Questions

The Lucira Check It COVID-19 Test Kit is a diagnostic test to detect SARS-CoV-2 which causes COVID-19. The test detects if you have an active infection and does not confirm immunity or detect antibodies. It is a molecular test that amplifies the virus’s genetic material while the test is running just like PCR lab tests. Lucira’s amplification method provides a level of accuracy comparable to one of the highest sensitivity lab PCR tests.

Yes, Lucira detects 99.9% of known COVID-19 strains, including the following SARS-CoV-2 variants:

  • Alpha (also known as B.1.1.7) first detected in UK,
  • Beta (also known as B.1.351, B.1.351.2, B.1.351.3) first detected in South Africa,
