Updating the app

If you booked a PCR test through the app, your test result will be sent automatically to the NHS COVID-19 app. Read about how to link your test result to the app if you booked a test a different way.

If you did not book a PCR test through the app you will get an 8-character long code from the testing service, by email or text which you can input into the NHS COVID-19 app.

If you did a rapid lateral flow test at home, and the result was positive, you should report a COVID-19 rapid lateral flow test result on GOV.UK. You will get an 8-character long code from the testing service, by email or text which you can input into the NHS COVID-19 app. If you get a positive lateral flow test result at home, you do not need to confirm the result with a PCR test unless in certain scenarios such as to claim the Test and Trace Support Payment in England, or if you have returned to England and tested positive on a rapid lateral flow test on Day 2. Read about when to get a PCR test.

By inputting a test result to the NHS Covid-19 app, the app can give you the most relevant guidance. You can also choose to share your result anonymously with 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.

If you are under 18 years old, and test positive for coronavirus, you should notify a trusted adult before taking any action.

Self-isolating

In England, you can leave self-isolation after 5 full days, as long as you test negative on day 5 and day 6. The first rapid lateral flow test must be taken no earlier than day 5 of your self-isolation period. You can then leave self-isolation on day 6 if both tests are negative and you do not have a high temperature. If either test is positive, you must continue to self-isolate until you get 2 negative rapid lateral flow tests taken on consecutive days, or you have completed 10 full days of self-isolation. If you leave isolation before the full 10 day period, you can disregard the app's countdown timer for the remaining days. It is a useful reminder to continue taking extra care during this period. You will not receive any close contact notifications until your 10-day count down timer ends. 

In Wales, you can leave self-isolation after 5 full days. You are strongly recommended to take a rapid lateral flow test on day 5 and day 6 to check if you are still infectious. The first rapid lateral flow test should be taken no earlier than day 5 of the self-isolation period. Tests should be taken at least 24 hours apart. If either of the rapid lateral flow tests taken on day 5 or day 6 is positive or you have a high temperature, you should remain in self-isolation until you've had 2 negative rapid lateral flow test results or you have completed 10 full days of self-isolation, whichever is sooner.

If you receive negative lateral flow test results on days 5 and 6 and leave self-isolation, you can disregard the app's countdown timer for the remaining days. It is, however, a useful reminder to continue taking extra care during this period. You will not receive any close contact notifications until your 10-day count down timer ends.

You should always follow the advice given to you by NHS Test and Trace or NHS Wales, Test, Trace, Protect

If you leave self-isolation before 10 full days you are strongly advised to:

  • limit close contact with other people outside your household, especially in crowded, enclosed or poorly ventilated spaces

  • wear a face covering in crowded, enclosed or poorly ventilated spaces and where you are in close contact with other people even if it is for a limited time

  • work from home if you can

  • limit contact with anyone who is at higher risk of severe illness if infected with COVID-19

  • follow the guidance on how to stay safe and help prevent the spread.
