Influenza A virus, Influenza B virus, Adenovirus, Coxsackie virus, Parainfluenza Virus Type1, Parainfluenza Virus Type2, Parainfluenza Virus Type3, Parainfluenza Virus Type4a, Enterovirus, Mumps virus, Respiratory syncytial virus, Rhinovirus, Bordetella pertussis, Haemophilus parainfluenzae, Staphylococcus aureus, Streptococcus agalactiae, Neisseria meningitides, Streptococcus sp. group A, Streptococcus sp. group B, Streptococcus sp. group C, Candida albicans, Human Metapneumovirus (hMPV), Legionella pneumophila, Mycobacterium tuberculosis, Mycoplasma pneumoniae, Pneumocystis jirovecii(PJP)-S cerevisiae Recombinant, Pseudomonas aeruginosa, Staphylococcus epidermis, Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus salivarius, Human coronavirus 229E, Human coronavirus OC43, Human coronavirus NL63 and MERS-coronavirus positive specimens.
However, a false result due to presence of these organisms at a level higher than tested cannot be ruled out.

Will this test hurt?

No, the nasal swab is not sharp and it should not hurt. Sometimes the swab can feel slightly uncomfortable or tickly. If you feel pain, please stop the test and seek advice from a healthcare provider.

I have a nosebleed after swabbing my nose. What should I do?
In the unlikely event your nose starts bleeding, apply pressure to your nose until the bleeding stops and consult a healthcare professional. Do not insert the Swab again.

How do I know that the test was run properly?

A procedural control is included in the test. A colored line appearing in the control line region (C) is considered an internal procedural control. It confirms adequate membrane wicking.

What should I do if the result shows positive?

You must take a laboratory PCR test immediately, self-isolate and contact your local health authority or the National Coronavirus Helpline on 1800 020 080 for further advice. You should also inform the immediate contacts you have had in past 24 hours so they can take any appropriate precautions.

What should I do if the result shows negative?

Negative results may require additional testing to confirm your results if you are symptomatic. If symptomatic, continue antigen testing every 24 hours for 3 days or take a laboratory PCR test. If asymptomatic, it is likely that you were not infectious at the time the test was taken. A negative test result, however, is not a guarantee that you do not have coronavirus. Please continue to follow social distancing, washing hands regularly and wearing masks as directed.
