COVID-19 Antigen Tests: What You Need to Know
COVID-19 antigen tests are also known as ‘lateral flow tests’. They are the tests you buy in shops and pharmacies and can use at home yourself.
They are not as accurate as PCR tests, which are the tests you book with the HSE. These are tested in laboratories.
Antigen tests are an extra measure to help protect yourself and others from COVID-19. You should know how and when they can be used.
How to Know What Test to Use
You should only use an antigen test if you do not have symptoms of COVID-19.
If you have symptoms, you need to self-isolate (stay in your room) and get a PCR test.
Antigen tests are not as accurate as PCR tests. That is why you need to be careful when using them.
If your antigen test gives you a positive result – you need to self-isolate (stay in your room) and get a PCR test.
Even if your antigen test gives you a negative result – you may still have the virus.
We know that this is confusing but our data shows that antigen tests are not accurate enough to tell you that you don’t have the virus.
