How to perform a rapid antigen test

Speaker 1

This video will explain how to do a rapid antigen test at home step by step.

It’s a quick and easy test for COVID-19 that helps keep schools safe and helps to pick up any cases as early as possible.

The rapid antigen test checks to see if your child has COVID-19 before they go to school.

Rapid antigen testing kits are available at all testing centres.

Children 12 years and older who want to be do the test themselves should be supervised to make sure they follow the steps correctly.

How to use the Roche rapid antigen test kit

Let’s look at how to use the Roche rapid antigen self-tests.

First, wash your hands.

Open the box and put all the materials in front of you.

The kit comes with written instructions too.

Have a timer or stop watch ready. Open one of the pouches marked with a ‘one’ (1) along the tear line and take out the test advice. You now need to perform the test straight away.

Open the silver foil pouch marked with the ‘two’ (2).

Take out one of the tubes with the liquid and a small cap with the pointy nozzle.

Open the tube with the liquid and make sure it is in the tube holder.

Next, blow your child’s nose and wipe it clean.

Now take out the swab - the small stick - out of the packaging. Only the touch the handle of the swab, not the soft tip.

Taking the sample

Now you’re ready to do the test.

Tilt your child’s had back.

Insert the swab about 2 centimetres into the left nostril.

Try to keep the swab flat and angled along the bottom of your child’s nose. Don’t point the swab upwards. Gently put the swab in and stop when you feel the back of your child’s nose. Then move the swab around in circles four times or for about 15 seconds.

Using the same swab, do the same on the other side. Two centimetres back and move it around four times on the right nostril.

Performing and reading the test

It’s time to get the result.

Put the swab into the tube so it is covered by the liquid.

Squeeze the tube tight and stir the swab about 10 times so that the material from your child’s nose is mixed into the test liquid.

You can now throw the swab out.

Take the small cap with the nozzle and seal the tube. With the test device on a flat surface, hold the tube above the little circular well and squeeze out 4 drops of the liquid into the well.

Set your timer and read the test result in 15 minutes.

Wash or sanitize your hands.

[Timer finishes]

Now you are ready to read the test result.

The device has two letters next to the result window. The C stands for ‘control’ and T stands for ‘test line. You should see a line next to C in all tests – the control line. It shows that the test it shows that the test has reacted to the liquid.

If there isn't a line next to the C, this test hasn't worked and you need to do another one.

The T line shows whether your child has tested positive for COVID-19.

A line next to the T means a positive result. Two lines gives a positive result.

It is likely your child has COVID-19. Your child should isolate immediately.

COVID-19 infection likely


You will need to report this result to your school straight away and take your child to get a standard PCR test at a local COVID-19 testing site to confirm the positive result.

If only the C line is showing, this is a negative result it is unlikely your child has COVID-19 especially if they have no symptoms.

[On-screen text]


But if your child has symptoms like a cold or flu your child must get a standard PCR test to be sure they don't have COVID-19.

Let's look at how to read the results again.

A line next to the c only means it is unlikely your child has COVID-19 especially if they have no symptoms.

If the test is negative but your child has cold or flu symptoms you should go and get a standard test at a testing centre.

Tell the testing centre about your child's positive rapid antigen test.

If a line did not appear next to the C, the test has not worked. You need to do a new test.
