What Does My Antigen Rapid Test (ART) Results Mean?

Even if your ART test result is negative, please stay vigilant.

Do continue to observe safe distancing measures and practice good personal hygiene such as regular handwashing and wearing a mask when leaving your home. Continue to monitor your health and test yourself where necessary.

If your ART test result is positive, you may be infected with the SARS-CoV-2 virus. Please take a photograph of your ART test results with your identification document (e.g. NRIC/passport) in the same photo immediately and visit a Swab and Send Home (SASH) clinic for a confirmatory Polymerase Chain Reaction (PCR) test.

The list of SASH clinics may be found at Bring (1) the photo of your results + ID together and (2) your physical ID (NRIC/Passport) to the clinic. If you are assessed by the doctor to meet the swabbing criteria, the cost of the confirmatory PCR test will be fully covered by the government.

If your ART test result is invalid, it may mean that the test was not performed correctly. You must perform a second test with another ART kit immediately.

If your second ART test is still invalid, please take a photo of the test result(s) with your identification document (ID) in the same photo and visit a SASH clinic immediately for a confirmatory PCR test. The list of SASH clinics may be found at Please bring (1) the photo of your results + ID together and (2) your physical ID (NRIC/Passport) to the clinic.

All COVID-19 Antigen Rapid Test (ART) kits are meant for initial screening and should not be the sole basis for diagnosis.
