There are different tests you can get to check if you have coronavirus (COVID-19). The test you need depends on why you're getting tested.
The 2 main tests are:
rapid lateral flow tests – only for people who do not have symptoms, the device gives a quick result
PCR tests – mainly for people with symptoms or if you are unvaccinated, they're sent to a lab to be processed
Both tests are free. You can get rapid lateral flow tests through the NHS COVID-19 app, and a PCR test through the app if you have been advised to do so. From the home screen menu there is a Testing for COVID-19 button which will take you to a link to where you can book a test.
