When Do Rapid Antigen Tests Work Best?

A rapid antigen test (RAT) is a test for COVID-19 infections. As the word suggests, ‘rapid’ means it is the quickest way to detect if you are positive with the virus within 30 minutes or less.

But do RATS really work? If they do, how accurate? What factors might affect their accuracy?

When Should You Get Tested for COVID-19?

If you have symptoms of COVID-19, it is important to get tested as soon as possible.  The earlier you are diagnosed, the sooner you can start treatment and avoid passing the virus on to others.

Among the types of tests available for COVID-19 are viral tests and antibody tests.

Viral tests detect the presence of the virus in your body. Antibody tests detect antibodies that your body has produced in response to the virus. If you have symptoms of COVID-19, you should get a viral test. A positive result means that you are infected and can spread the virus to others.


If you do not have symptoms, but think you may have been exposed to the virus, you should get an antibody test. A positive result means that you have been exposed to the virus and may have some immunity to it.

You should get tested as soon as possible if you have any of the following symptoms:

  • Fever
  • Cough
  • Shortness of breath
  • Chills
  • Body aches
  • Headache
  • Sore throat
  • Loss of taste or smell.

If you have been in close contact with someone who has COVID-19, you should also get tested. You can get a viral test at your doctor’s office, a clinic or a hospital. You can also get a test through a drive-thru site or by mail.

What Is a Rapid Antigen Test?

Rapid antigen tests are a type of medical test that can be used to detect the presence of a specific virus or bacteria in a person’s body. They are often used to diagnose infections, such as influenza, strep throat and COVID-19.

The rapid antigen test is used to detect the presence of antigens associated with the SARS-CoV-2 virus. Antigens are proteins that are found on the surface of viruses and other microorganisms. The test can be performed using a nasopharyngeal (NP) swab, oropharyngeal (OP) swab or saliva specimen. 

What Are The Benefits of Rapid Antigen Test?

There are several advantages to using rapid antigen tests in Brisbane over other types of diagnostic tests, such as PCR tests. Some of the main benefits of using rapid antigen tests include:

COVID rapid antigen tests can usually be done in a matter of minutes, which is much faster than other types of diagnostic tests.

COVID rapid antigen tests are typically less expensive than PCR tests, making them a more affordable option for many people.

Rapid antigen tests are able to correctly identify the presence of a virus or bacteria in most cases.

COVID rapid antigen tests can often detect infections early, which allows for early treatment.

Rapid antigen tests can be used to quickly screen large groups of people for the presence of a virus or bacteria, which is helpful in controlling the spread of infection.
