SARS-COV-2 Antigen Test Instructions

Antigen testing is one of the fastest methods for COVID-19 testing, and many healthcare workers use it. In a world where detecting the virus on time is vital, this testing method is optimal. 

The SARS-COV-2 antigen rapid test detects the presence of a certain viral antigen related to COVID-19. It can be carried out on saliva or nasal swab specimens, which are then placed in an extraction buffer or reagent. 

While simple, this process can be confusing for some. Hence, this article will cover all you need to know about rapid tests, from when you should get tested to SARS-COV-2 antigen test instructions and tips.

When You Should Get Tested for COVID

If you exhibit symptoms of the SARS-COV-2 virus or have come into touch with someone who may have the condition, consider performing a COVID-19 test to determine whether you have this severe disease.

It is essential to take the test before attending an indoor gathering with others. Even if you do not have any symptoms and have not been exposed to someone who has it, you should still perform a self-test to assess whether you are likely to spread the virus. 

This is especially important to do before an event that includes children, adults, older people, persons with compromised immune systems, or those at an increased risk of developing a serious illness. 

Repeated self-testing, also known as serial self-testing, is when a person evaluates themselves for COVID-19 on a repeated basis, such as once every few days. 

Repeated self-testing can be done once every few days or several times. By conducting tests on a more consistent basis, you increase the likelihood of detecting the COVID-19 virus at an earlier stage and halt the further development of the infection. 

You can try two standout tests to get accurate results: the Healgen Covid-19 rapid test and the FlowFlex Covid-19 rapid antigen test. These products are highly accurate and are backed by the UK government.

  5. Take your swab sample by inserting the swab tip 2.5 cm into one nostril and rotating the swab five times. Use the same tip in the second nostril. 
  6. Perform the same method in step 5 for other people, but stop inserting the swab when you feel resistance.
  7. Process the sample using the SARS-COV-2 antigen test cartridge. Take care testing the sample to ensure you do not ruin the process.
  8. Wait 15 minutes for the result,
  9. Read the result.
  10. Report the result.
  11. Discard the test kit and sample safely.
