Antigen tests for children

The information on this page is about using antigen tests you buy in a shop or pharmacy.

Most children do not need to get tested for COVID-19.

If your child has symptoms

Your child should stay at home and avoid contact with other people if they have symptoms of COVID-19 and:

  • are unwell
  • have a high temperature (38 degrees Celsius or higher)

How to do an antigen test with your child

To do the antigen test you use a swab to take a sample from your child's nose.

When you have finished with an antigen test, put it in a plastic bag and put the bag in your bin.
