The following COVID-19 rapid antigen tests (home use tests) are now available in Australia as of November 1, 2021, thanks to TGA approval.

It’s crucial to adhere to the guidelines provided for the particular exam you take. The table below lists the instructions for each test.

More details are available in COVID-19 rapid antigen tests (for home use), including where to buy rapid antigen tests, what to look for, how to use them properly; what to do if you are traveling abroad with a COVID-19 self-test; how to report a problem or issue with a COVID-19 self-test; and how to legally supply and advertise COVID-19 rapid antigen tests in Australia.

The sale of COVID-19 nucleic acid amplification rapid antigen tests (for use at home) is also authorized in Australia. Instead of the spike protein picked up by fast antigen testing while the infection is active, nucleic acid amplification (NAA) assays find the genetic material from the SARS-CoV-2 virus.

The World Health Organization (WHO) and the European Commission have also produced technical standards that correspond to the TGA’s performance criteria for the COVID-19 rapid antigen test. This calls for a clinical sensitivity of at least 80% (for samples taken within 7 days of symptom onset) and a clinical specificity of at least 98% for quick antigen testing.

Rapid antigen tests that come be done at home

The performance of the COVID-19 rapid antigen tests is shown in the table below, along with details on the clinical sensitivity of each test. This is based on manufacturer studies that demonstrate a high percentage of agreement (PPA). PPA measures how many people tested positive for COVID-19 using a fast antigen self-test against how many people tested positive using a more accurate PCR test.

Since all authorized rapid antigen tests satisfy the performance standards, the publication of this material does not imply TGA endorsement of any specific test. You may examine the manufacturer’s sensitivity information by clicking on the links in the table below, which is also included in the instructions that come with each test. The following clinical sensitivity remark is given for each test:

  • Clinical sensitivity of more than 80% PPA is considered acceptable.
  • Clinical sensitivity of more than 90% PPA, or high sensitivity.
  • Clinical sensitivity is more than 95% PPA, which is very high sensitivity.

How reliable are quick diagnostic procedures?

If fast diagnostic tests are as accurate as traditional testing, you may be wondering. Do they, for instance, sacrifice precision for speed?

In a word, kind of. However, they are still commonly regarded as trustworthy testing choices.

The gold standard for precise testing is standardized molecular analysis. However, they are not entirely correct. The coronavirus is particularly specific to rapid antigen testing. If the test is positive, you are probably contaminated. There is a larger possibility of receiving a false negative result with fast antigen testing since they are less sensitive than other tests.

Additionally, there were worries that quick molecular tests were omitting a significant portion of positive instances when they initially became accessible. Particularly troubling was Abbott’s quick ID NOW test. Some individuals who could have had the virus tested negative. This is referred to as a misleading negative outcome.

How reliable are quick diagnostic procedures?

However, real-world data reveals that the ID NOW test is trustworthy, according to manufacturer research. When compared to the outcomes of conventional molecular tests, the ID NOW test was able to detect 93% of positive samples and over 98% of negative samples, according to Abbott. Abbott has lately claimed that its test can identify the Omicron variation in addition to other variants.

However, be aware that in addition to the ID NOW exam, there are other fast tests. They are all inaccurate to differing degrees.

Additionally, when you test early in the illness, fast tests generally tend to be more accurate. The optimal time to be tested is when your body has the most viruses present (maximum viral load). The likelihood that the test will detect the virus in a sample rises with a larger viral load. For instance, it has been shown that the quick ID NOW test is more accurate when administered within 7 days after the onset of symptoms.

Additionally, COVID-19 tests aren’t intended to look for certain viral subtypes. They are intended to do a thorough virus test. The FDA takes notice if a particular test is shown to be unable to accurately detect a viral variation. Click or touch here for a list of tests that may not be effective with certain variations.

Ideal rapid diagnostic testing

The ideal test is one that is: 

  • Quick 
  • Simple 
  • Affordable 
  • Accurate

CRISPR-based diagnostics, according to researchers, have the ability to fulfill all of these criteria.

Clustered regularly interspaced short palindromic repeats are known as CRISPR. Many think that this potent gene-editing technique may be able to treat hereditary illnesses in humans. According to recent studies, it could also be helpful in identifying COVID-19. Click here to read about What are genome editing and CRISPR-Cas9?

The first COVID-19 test based on CRISPR was approved in May 2020, and it generates findings in roughly one hour. Since then, two other CRISPR experiments have been approved: one in July 2021 and one in January 2022. CRISPR uses molecular “scissors” to recognize and cut through the genetic material of viruses, aiding in the virus detection process.

What are the prospects for these COVID-19 rapid antigen tests based on CRISPR? Will future authorities allow for even more? In an effort to reduce the need for testing, businesses are developing them into a simple and affordable substitute. Visit to read about The process of rapid antigen tests.

In my area, where can I obtain fast testing?

You should get in touch with your doctor or the health department if you have COVID-19 symptoms or think you may have been exposed to the virus to find out whether you need to get tested.

You may have various alternatives if you want a test with quicker results. You may need to fulfill certain requirements, such as symptoms or exposure risk, depending on where you live and where you go for testing. You may be required to complete a brief questionnaire when making an online appointment reservation to make sure you satisfy the criteria.

The majority of testing locations use the COVID-19 standard molecular rapid antigen tests. Some could provide quick diagnostic testing, although supply is often scarce. The rapid antigen tests might also be known as:

  • Rapid tests
  • Rapid point-of-care testing
  • Same-day exams
  • 15-minute exams; instant tests
