7 pointers to help you achieve a precise result

The TGA website has instructions on how to utilize authorized rapid antigen tests, and in order to compile these pointers, we analyzed those instructions. Take into consideration the following:

  • Make sure you verify the date it expires. Do not utilize rapid antigen tests that have passed its expiration date.
  • Before using some rapid antigen tests, they need to be allowed to reach room temperature and sit there for half an hour. Therefore, prepare in advance.
  • If you are going to be collecting a sample using a nasal swab, blow your nose before you do so. If you are going to use a saliva test, you should not eat or drink anything for the previous ten minutes before collecting the sample.
  • Make sure the sample doesn’t become contaminated. No matter the rapid antigen tests you decide to employ, the instructions will likely advise you to clean a flat surface, wash or sanitize, and dry your hands, and then arrange the test materials in a certain manner. It is imperative that you under no circumstances touch the business end of the swab (also known as the soft end that goes in your nose), since doing so will inevitably contaminate it.
7 pointers to help you achieve a precise result
  • 5. Be sure to collect your samples exactly according to the instructions provided. For instance, if you are using a nasal swab, you will be instructed to push it into each nostril for two centimeters, spin it five times, and repeat the process. After the sample has been obtained, it is then added to the chemical solution.
  • 6. Transfer a predetermined amount of the solution to the indicator device in the form of drops. You shouldn’t add anything more like “for good luck.”
  • 7. It is important to read the findings at the precise time that was suggested. For instance, the instructions may direct you to read the result 15 minutes to 20 minutes after applying the solution, with no time in between those two extremes being acceptable. After twenty minutes, the accuracy of the result may no longer be reliable.

What exactly does each different colored line mean?

There are two lines of different colors that need to be found. One is the letter C (the control). This will inform you whether or not the test is functioning accurately. The other option is a test or an activity (antigen). The following is what happens when all of these factors are brought together:

  • Rapid antigen tests are considered to be faulty if the line colored C does not appear. • if the C-colored line appears but the T (or Ag) line does not, your result is negative (you are unlikely to have COVID-19) and the test kit may have expired; if you did not do the test properly. if the C colored line shows and the T (or Ag) line does not.
  • If the C line, as well as the T line (or Ag line), appears, this indicates that your test is positive and that you most likely have COVID-19.

What comes next?

Congratulations are in order if the test comes back negative and you don’t have any symptoms. If you get a negative result but still have symptoms, you should have a PCR test to confirm your suspicions. In the meanwhile, you should try to avoid making contact with other people.

In the event that you get a positive result, you should immediately do a PCR test to confirm the result, and in the meantime, you should self-isolate.
