What happens at the test site

When you visit the test site, you’ll take a new type of coronavirus test called a lateral flow test. This is a swab test that gives results in less than an hour. It does not need to go to a lab.

The test checks if you’re infectious, even if you do not have symptoms.

You’ll be given instructions to follow. The test involves taking a swab of the inside of your nose and the back of your throat.

You’ll swab yourself, then trained staff will process the result.

Your result
You’ll get the results on the same day, by text or email.

If you test positive, you must self-isolate.

Download the NHS COVID-19 app and input your test result .

Lateral flow tests are very accurate.
