This is a NHS video on how to do a lateral flow test (LFT).

What do I do next?

You need to book a more accurate PCR test. Advice on this is changing.

PCR tests must be pre-booked via the Gov.UK website, or by calling 119. You cannot drop in for a PCR test.

Negative LFT result

If there is one line next to C (and no line next to T), your LFT is negative – like the one on the left above.

Void LFT result

If there is one line next to T (and no line next to C), or no lines, your LFT  is not working properly – and you should repeat it (if necessary from another set of kits).

Why is a COVID-19 LFT test done?

A LFT test is a reliable (but not perfect) and quick test for COVID-19. This is why it is done. In other words it is used as a first simple test for COVID-19. It has the advantage of being able to be done in 10 minutes at home (but is less accurate).
