Lateral flow testing

Latest update - from 6 January

If you get a positive rapid lateral flow test result, most people will not need to take a PCR test to confirm the result. You must self-isolate immediately if you get a positive rapid lateral flow test result.

There is additional guidance for those working in health and social care and special educational provision.


About 1 in 3 people with coronavirus do not have symptoms but can still infect others.

Getting tested regularly is one way to know if you have the virus. If people test positive and self-isolate, it helps break the chain of transmission and limits the spread of the virus.

Rapid lateral flow tests (LFTs) are only for people who do not have coronavirus symptoms.

If you have COVID-19 symptoms you need to book a PCR test

You should still get tested if you have been vaccinated. Even if you’re fully vaccinated, there’s still a chance you can contract COVID-19 and pass it on.

‘Flow before you go’. Take a lateral flow test if you don’t have symptoms before going out, especially when meeting others.
