  • This test kit has not been reviewed by the FDA.
  • Negative results do not preclude acute SARS-CoV-2 infection. If acute infection is suspected, direct testing for SARS-CoV-2 is necessary.
  • Results from antibody testing should not be used to diagnose or exclude acute SARS-CoV-2 infection.
  • Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.
