If you book your test through the NHS COVID-19 app, your test result will be updated automatically in the app. However, if you booked a test a different way, you may still be able to link your test result to the app.

You will get an 8-character long code from the testing service, by email or text, if:

  • You have symptoms of coronavirus, and book a test through the official testing website (this is how most people get a test).

  • You do not have symptoms of coronavirus, but get a test in a Mobile Testing Unit, because your postcode has high levels of a variant of concern (this is sometimes known as surge testing).

  • You have taken a rapid lateral flow test (LFD) and report your result online. You will only get a code if your rapid lateral flow test result is positive.

  • You get a test in an NHS England hospital, through a Public Health England lab (which carry out tests for NHS hospitals), or in a surveillance study, and test positive for coronavirus. If you test positive but do not receive a code to link your result to the app, you can request one when contacted by NHS Test and Trace.

To link your test result to the app, select 'Enter test result' on the home screen of your app. Then, enter the 8-character code you received from the testing service.

By linking a test result to the app, the app can give you the most relevant guidance. You can choose to share your result without being identified. Other app users you have been in ‘close contact’ with over the last few days will then receive an anonymous notification on their app. Read more about who gets an alert if you test positive.
