Rapid antigen tests, also known as RATs, are a quick way to test if you have COVID-19.
You can buy rapid antigen tests in pharmacies and supermarkets.
There are different types of rapid antigen tests you can use to check if you have COVID-19.
Some use your saliva, while others use a sample collected from inside your nose.
Each test works a little differently, so you must follow the instructions carefully to make sure you get an accurate result.
Results may take up to 30 minutes to show.
Remember, a test can only be used once.
