In this video, Dr Mark Wenitong explains how to use a nasal rapid antigen test (RAT) to test for COVID-19.


Hi, I’m Dr Mark Wenitong, and I want to show all you Mob the right way to use a Rapid Antigen Test – or RAT Test – to check to see if you have COVID-19.

If you’ve been in contact with someone who has COVID-19, or you have symptoms like fever or cough, it’s good to test to see if you have COVID.

A RAT can be an easy way to see whether or not you have COVID. And you can do the test yourself without a doctor, in the comfort of your own home, and get the results in just 10 to 20 minutes.

You can buy RATs from your local pharmacy, supermarket and lots of other retail stores, as well as online.

You can also check on your state or territory health department website.

There are a few different types of RAT kits available – but the three most common are one that tests the spit from your mouth, one that you suck like a lollipop, and one that takes a sample from your nose.

Remember, no matter what test you have, before you start, wash your hands and make sure you have a watch or timer handy.

If you’re using a RAT that takes a sample from your nose, inside your kit you’ll find a strip that will show you if you have COVID-19 or not, a long stick with 1 soft end, a tube with lid and a small pack with liquid called the buffer.

Some kits also have a stand and a torch. First, make sure you have the tube the right way up. Your test kit might come with a stand to help.

Be careful not to let the tube fall over. Open a pack with a buffer and pour it into the tube, making sure to not get any on your skin or eyes. Take the stick out of the packet, making sure you don’t touch the soft part of the stick.

Put the soft part up your nose, all the way up until it you feel it touch the back of your nose. Keep moving the stick around.

Use the soft end of the same stick and do the other side of your nose. When you’re done put the stick into the tube and stir it 10 times.

Then, gently squeeze the sides of the tube together 10 times before taking the stick out. Put the cap tightly on the tube. Put the cap tightly on the tube. Get the strip that will show you if you have COVID-19.

Squeeze three or four drops from the tube onto the circle at the bottom and set your timer for 10, 15 or 20 minutes, depending on what your kit says And you wait. No matter what type of test you use, once your timer is up, check the strip to see what it says. Make sure you do it straight away, as it can be inaccurate if you leave it too long.

One RAT even has a torch to help you read the strip. If you see a line next to the C, you don’t have COVID-19.

If you see a line next to the C and the T, you are positive for COVID-19. If you only see one line next to the letter T, or no lines at all, your test didn’t work and you’ll need to do another test.

If you’re worried about your symptoms, or if you have other health conditions call the National Coronavirus Helpline or speak to your healthcare worker.

So remember, if you need to test yourself for COVID-19, get a RAT. It’s easy and will help keep all us Mob safe. If you need to know more, have a yarn with your local healthcare worker or visit
