Here’s how you should use the RTK Antigen Test at home

by Grace Sundram

The RTK Antigen Test is a rapid test to detect the SARS-CoV-2 antigen found in human saliva. This test kit is user-friendly, non -invasive and can be made yourself.


How to know whether it’s negative or positive:


A red line appears in section “C” and no red line appears in section “T”.

continue to adopt appropriate safety management measures as well as maintain good personal hygiene.


Two different red lines appear in the “C” and “T” sections.

You will need to visit a health facility near you to undergo an RT-PCR test to confirm the diagnosis.

Test results can also be reported through the MySejahtera application. You just need to open the MySejahtera application> Press Helpdesk> Press Start> Select option F which is “I have been confirmed positive for Covid-19 and am waiting to be contacted by MOH.

Invalid result

No coloured lines appear, or red lines appear only on the “T”.

Please contact the pharmacy or clinic for any questions

Remember, the RTK-Antigen Test is a screening tool as it can only detect SARS-CoV-2 antigen in human saliva alone, not other samples.

If the procedure is done incorrectly, it can lead to inaccurate results.

Positive results do not rule out the probability of infection of other pathogens.

Therefore, due to the limitations of this test in the detection and sensitivity range, the RTK-Antigen test can only be used as a screening test while the RT-PCR test is used as a confirmatory test to determine the case of COVID-19.

Regardless of your test results, make sure you always adhere to the SOPs at all times to protect yourself as well as the people you love around us. We can do this by:

  • Maintaining a social distance of at least one meter from others.
  • Wear a face mask at all times.
  • Wash or clean your hands regularly.
  • Avoid crowded places and only go out when necessary (for example: buying essential items).

Let’s work together and do our part in stopping the spread of COVID-19.
