Do not freeze and do not store the test kit in direct sunlight. All components must be bought to room temperature before testing. Do not use after expiry date. Sample Collection Do I need to insert the swab into my both nostrils to take sample? Yes, you must take the samples from your both nostrils. Test Operation How many drops should I add in both sample wells? You should add 3 drops using the buffer tube into all three samples wells noted as "S" on the cassette Don't know how long I should wait to read my results? Make sure you wait for 15 minutes, and then read your results at 15-20 minutes Read Results How do I know if the test was run properly? A coloured line will appear in the control region (C) of the test cassette if the test has been properly performed. If this line is not visible, then the test has been incorrectly performed and you must run a new test or call customer support. There is a faint/weak line appearing at A, B or T, should this be still considered as positive? Yes, even if there is a faint line at the region A, B or T or all, results must be considered as positive. The red line appeared in the control (C) region only on some of the strip/s and did not appear on one or two strips. Does that mean the test is invalid for all 3 viruses? No, it means test must be considered invalid only for those virus where red line is absent on control (C) region. Results are valid for any test where control region (C) is present. Don't know how deep I should insert the swab into my nostrils? Gently insert the swab about 2cm (soft head of the swab) into your nostrils.Do not insert the swab deeper if you feel strong resistance or pain.

A negative result does not rule out infection with another type of respiratory virus (other than SARS-Cov-2, Influenza A/B and RSV). 4. A negative result does not mean a person is not infectious or does not have COVID-19, Influenza A/B or RSV. If symptoms persist the person should seek medical attention and further testing if required. 5. Positive test results do not rule out bacterial infection or coinfection with other viruses 6. A false negative test may result if the level of antigen in the sample is below the detection limit of the test or if the sample was collected incorrectly. 7. If the result is positive for SARS-CoV-2, please contact the relevant state or territory health authority for guidance on confirmation testing. 8.If positive for Influenza A/B or RSV are feeling unwell, consult a medical practitioner for follow-up clinical care.. 9. The test is less reliable in the later phase of infection and in asymptomatic individuals. 10. Children aged 4-18 years old should have the samples collected and tested by an adult. Do not use on Children under 4 years of age. 11. False negative results are more likely to occur if the test is performed after 7 days of symptom onset for SARS-CoV-2 and after 4 days of symptom onset for Influenza A/B and RSV. 12. Even if the result is negative, you still need to observe all protective and hygienic measures, 13. Repeat Testing is recommended (between 24-48 hours after your first test if there is ongoing suspicion of infection, being high risk settling or where there is an occupational risk or other requirement. 14.
