A COVID-19 rapid lateral flow test shows you the result on a device that comes with the test.

How to do a COVID-19 rapid lateral flow test

How you do the test depends on the test kit you’re using.

Rapid lateral flow tests require either a:

• throat and nose swab
• nose swab only

The test you have might be different to one you've done before so it's important to read the instructions carefully before you do the test.

Information: Check the expiry date before you do the test

Rapid lateral flow tests have expiry dates so you know when to use them by.

Do not use out-of-date tests. Use a test from a box which is still in date.

Before taking the swab

• wash your hands with soap and water or use a hand sanitiser
• clear, clean and dry a flat surface then lay out all the items in the test kit
• if your test does not come with a pre-filled tube, fill the tube with the liquid provided
• place the tube in the tube holder
• blow your nose
• wash your hands again or use a hand sanitiser

Taking the swab

If your test requires a throat swab:

• open your mouth wide and rub the swab over both your tonsils (or where they would have been) at the back of your throat. Do this 4 times on each side
• using the same swab, wipe the inside of your nose as set out in the test kit instructions

If your test requires a nose swab only:

• use the swab to wipe the inside of your nose as set out in the test kit instructions

Completing the test

• put the end of the swab into the tube so it's in the liquid and swirl the swab around as directed in the test kit instructions, then close the lid
• squeeze the liquid from the tube onto the test strip
• check the waiting time in the instructions that came with your test kit
• wait for the time shown in your test kit instructions
• read your result

Do not leave it longer than the waiting time specified in the test kit instructions as this may affect the result.
