What are the type of swab the antigen test kits that Aussie Pharma Direct have?

The InnoScreen, CTK Biotech and Fanttest RATs use nasal swabs.

What is a rapid antigen test?

A rapid antigen test is a diagnostic test that detects the presence of specific viral proteins, or antigens, in a person's sample, typically collected from a nasal or throat swab. This type of test is commonly used for the detection of COVID-19, as well as other infectious diseases.

What is a combination test kit?

A combination test kit typically refers to a test that can detect multiple viruses or pathogens, including but not limited to COVID-19. These tests are designed to simultaneously detect different respiratory viruses, such as Influenza A/B and the novel coronavirus SARS-CoV-2, in a single assay. By offering the capability to detect multiple viruses, combination test kits can provide a comprehensive diagnostic solution. They can be particularly valuable during flu seasons or when there is a need to differentiate between respiratory illnesses with similar symptoms.

How do I conduct a rapid antigen test?

Preparation for procedure

1. Gently blow your nose into a tissue to remove excess mucus.

2. Wash your hands thoroughly with soap and water or use hand sanitiser before handling the package. Unpack the test components. DO NOT DISCARD the box until you have made sure that you have all components required. DO NOT USE if they are expired or damage.

Sample Collection

1. Open the sealed pouch containing the test cassette and remove it.

2. Place the test cassette on a clean and flat surface. DO NOT TOUCH the test window.

3. Place the extraction tube on a secure place to avoid spilling of buffer (use the hole on the box or tube stand if provided with your kit). Unscrew the blue cap. Keep the cap aside, DO NOT DISCARD.

4. Open the sealed pouch containing the swab and hold it by the handle.

5. Gently insert the swab into the nostril, parallel to the palate, until resistance is met (about 2 cm or until you feel slight resistance).

6. Rotate the swab around the inside of the nostril at least 5 times for a total of 15 seconds. Remove the swab then repeat the process with the other nostril.

7. Place the swab into the extraction tube. Squeeze the lower part of the tube against the swab tip inside the tube 15 times.

8. Squeeze the sides of the extraction tube to release the solution and transfer it to the sample well of the test cassette.

9. Start timer and read results at 15 minutes. Wait for the colored lines to appear on the test cassette, indicating the test result.

10. After reading the result, place all the used components in the plastic bag provided and dispose into a general waste bin.

How accurate are rapid antigen tests?

Rapid antigen tests are generally considered to be less accurate than PCR tests, but their accuracy depends on various factors such as the time from infection, viral load, and the quality of the test kit. At Aussie Pharma Direct, we distribute InnoScreen and CTK Biotech rapid antigen tests. The rapid antigen test accuracy are as below:

InnoScreen Rapid AntigenTestThe test offers 92.31% sensitivity and 100% specificity to aid in the early diagnosis of COVID-19

CTK Biotech Rapid Antigen TestThe test offers 94.7% sensitivity and 100% specificity to aid in the early diagnosis of COVID-19

What is the difference between PCR test and rapid antigen test?

The main difference between PCR (Polymerase Chain Reaction) tests and rapid antigen tests is the method used to detect the virus.

PCR tests detect the presence of viral RNA, which is the genetic material of the virus. The test involves amplifying and detecting viral RNA using a laboratory-based technique, which can take several hours to days to produce results.

On the other hand, rapid antigen tests detect the presence of viral antigens, which are proteins on the surface of the virus. Rapid antigen tests are designed to provide results quickly, typically within 15 minutes, and can be performed at the point of care, such as in a doctor's office, a pharmacy, or at home. However, rapid antigen tests may not be as sensitive as PCR tests and may produce false-negative results, particularly if the viral load is low.

How long do the results take to show?

To interpret the results, read results at 15 minutes. Results should not be read after 20 minutes. 

What do I do if I test positive for COVID-19?

If you test positive for COVID-19, it is important to take the following steps to protect yourself and others:

1. Isolate yourself: Stay home and avoid contact with other people as much as possible.

2. Notify close contacts: Inform anyone you have been in close contact with recently that you have tested positive for COVID-19. This will allow them to take necessary precautions and seek testing if needed.

3. Monitor your symptoms: Keep track of any symptoms you may experience and seek medical attention if they worsen or if you have trouble breathing.

Are rapid antigen tests accepted in Australia?

Yes, rapid antigen tests are accepted in Australia and have been approved for use at home by the Therapeutic Goods Administration (TGA) for detecting SARS-CoV-2 virus in individuals who are suspected of COVID-19. However, it's important to note that not all rapid antigen tests have been approved by the TGA, and only tests that have met the required standards for accuracy and reliability are authorised for use in Australia.

For more information, visit the TGA website.

Are these rapid antigen tests TGA approved? 

Yes, our RATs are all TGA approved.

How do I dispose of my test?

It is important to dispose of your rapid antigen test kit properly to prevent the spread of COVID-19 and other infectious diseases. After using the test, place all used items in the biohazard bag that is usually provided together with the kit. Make sure to seal the bag properly to reduce the risk of contamination. In most cases, you can dispose of medical waste in the regular trash, but be sure to check with your local health department or waste management agency to confirm.

What do my results mean?


Only one coloured line appears in the control region. Only one purple line only next to “C” indicates negative


Two coloured lines appear in control region and test region. One purple line next to “C” and one purple line next to “T” Indicates COVID-19 positive. **The colour intensity in the test region “T” may be faint. Any pink/purple line visible next to “T” is positive. Anyone who tests positive should refer to your local State or Territory Health Department for guidance on confirmation testing if necessary. If you are unwell, seek medical assistance.


No coloured line appears in the control region. No purple line next to “C” indicates invalid

How do I store the rapid antigen tests?

It is recommended for the rapid antigen tests to be stored in a cool, dry place between 2 - 30°C.

Can InnoScreen and CTK Biotech rapid antigen tests pick up other viruses?

InnoScreen and CTK Biotech rapid antigen tests are designed to detect specific viral antigens and are optimised for the detection of a particular virus, such as SARS-CoV-2, the virus that causes COVID-19. These tests are not designed to detect other viruses and may not be able to pick up other viral infections.

If you suspect that you have contracted a different type of virus or are experiencing symptoms of illness that are not normal to COVID-19, it's important to seek medical attention at a clinic or hospital. A healthcare provider can conduct a physical examination, take a medical history, and perform diagnostic tests, if necessary, to determine the cause of your symptoms and recommend appropriate treatment.
