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.

  • If you book a test through the official testing website, which is the vast majority of people, you will receive a code allowing you to link your test result to the NHS COVID-19 app

  • If you get a test in an NHS hospital in England, through a Public Health England lab (which carry out tests for NHS hospitals), or in a surveillance study, and test positive for coronavirus, you can request a code when contacted by NHS Test and Trace

  • If you have taken a rapid swab test, also known as an LFD (lateral flow device) test, at a test site or lab, and your result is positive, you will receive a code and should enter this into the app

To link your test result to the app, select Enter test result on the home screen of your app. Then, enter the code you received from the testing service by email or text.

By linking a test result to the app, the app can give you the most relevant guidance. You can also choose to share your result anonymously. The NHS will then send alerts to other app users who have spent time near you, or in ‘close contact', over the last few days. These alerts will never identify you as an individual. Read more about who gets an alert if you test positive.
