Interpreting your rapid antigen test results correctly is key to understanding your potential infection status. Here's a guide to what the line combinations typically indicate: Positive Result COVID-19 Positive Result A colored line appears at the control region (C) and a second colored line at the test region (T). Influenza A Positive Result A colored line at the control region (C) and a second colored line at the A test region. COVID-19 and Influenza A Positive Result Two colored lines at the control region (C) and lines at both the T and A test regions. COVID-19 and Influenza A & B Positive Result Two colored lines at the control region (C) and lines at all test regions (T/A/B). Influenza A & B Positive Result A colored line at the control region (C) and lines at both the A and B test regions. Influenza B Positive Result A colored line at the control region (C) and a second colored line at the B test region. COVID-19 and Influenza B Positive Result Two colored lines at the control region (C) and lines at both the T and B test regions. Negative Result A single colored line appears at the control region (C) and no lines appear at any test region (T/A/B). This suggests you are unlikely to have COVID-19 or Influenza A/B, but it's always best to consult with a healthcare professional. Invalid Result No colored line at the control region (C) for either COVID-19 or Influenza A/B. An invalid result means the test didn't work correctly, and you'll need to retest using a new test kit and extraction reagent. If you have a positive result, follow the specific guidance provided with your test kit and seek medical advice as needed. Always dispose of used test kits properly, following local guidelines.
