How to do a COVID-19 rapid lateral flow test

How you do a COVID-19 rapid lateral flow test depends on the test kit you’re using.

COVID-19 rapid lateral flow tests use either a:

  • throat and nose swab (like a cotton bud)
  • nose swab only
Information:

The test you have might be different to one you've done before. It's important to read the instructions carefully and check the expiry date to make sure the test is still in date before starting.

Preparing for the test

Follow the instructions given in the test kit about how to prepare for the test. Including about washing your hands and blowing your nose.

Doing the test

If your test uses a throat and nose swab:

  1. open your mouth wide and rub the swab over both your tonsils at the back of your throat, or where they would have been if you’ve had them removed – do this 4 times on each side
  2. using the same swab wipe the inside of your nose, as explained in the test kit instructions

If your test uses a nose swab only:

  1. wipe the inside of your nose with the swab, as explained in the test kit instructions

Completing the test

To complete the test:

  1. put the end of the swab into the tube so it's in the liquid and swirl the swab around as explained in the test kit instructions, then close the lid
  2. squeeze some drops of liquid from the tube onto the test strip (the test kit instructions tell you how many drops)
  3. wait for the time shown in your test kit instructions
  4. read your result

Do not leave the test longer than the waiting time given in the test kit instructions, as this can affect the result.

COVID-19 rapid lateral flow test results

COVID-19 rapid lateral flow tests show the result on the testing device within a few minutes.

You do not need to report the result from a COVID-19 rapid lateral flow test if you live in England, whatever the result.

What your COVID-19 rapid lateral flow test result means

Positive test result

If you get a positive COVID-19 rapid lateral flow test result, it means it’s very likely you have COVID-19.

If you test positive for COVID-19, try to stay home and avoid meeting people for:

  • 3 days after the day the test was taken if you’re under 18 years – children and young people tend to be infectious for less time than adults
  • 5 days after the day you took your test if you’re aged 18 or over

Try to wait 10 days after the day you took your test before meeting anyone who is more likely to get seriously ill from viruses, such as someone with a weakened immune system.

If you test positive and you're eligible for COVID-19 treatments, call your GP surgery, NHS 111 or hospital specialist as soon as possible.

Negative test result

If you get a negative COVID-19 rapid lateral flow test result, it means it's unlikely you have COVID-19.

There's still a chance you could have the virus, so you should follow the advice on how to avoid catching and spreading COVID-19.

If you test negative and you’re eligible for COVID-19 treatments, you need to do a total of 3 rapid lateral flow tests over 3 days (1 test a day) if you continue to have COVID-19 symptoms.

Test result could not be read

If your test result could not be read, it’s not possible to say if you had COVID-19 when the test was done. Some tests may call this a void result.

Do another test as soon as possible.
