There are 3 outcomes of your test:

  • Positive - You are infected with the SARS-CoV-2 virus. Please immediately follow NHS England guidance on isolation.
  • Negative - You are not infected with the virus. Please continue to take sensible precautions, if you were self-isolating as an international arrival you may stop self-isolating, per GOV.UK guidance.
  • Invalid - Occurs in 1-3% of samples. Typically (but not exclusively) this arises when insufficient human material is present on the swab sample, and is more frequent with Self-test kit samples. It can be mitigated by using our practitioner-led testing service. You must continue to isolate as an international arrival and you must repeat the test.
