Interpreting the Results

COVID-19 Positive  +





If the Control (C) line and the Test (T) line are visible, the test is positive. Any faint visible red test (T) line with the control line (C) should be read as positive. You do not need to perform repeat testing if you have a positive result at any time. A positive test result means that the virus that causes COVID-19 was detected in your sample and it is very likely you have COVID-19 and are contagious. Please contact your doctor/primary care physician or your local health authority immediately and adhere to the local guidelines regarding self-isolation. There is a very small chance that this test cangive a positive result that is incorrect (a false positive).

COVID-19 Negative  -


​If the Control (C) line is visible, but the Test (T) line is not visible, the test is negative. To increase the chance that the negative result for COVID-19 isaccurate, you should: · Test again in 48 hours if you have symptoms on the first day of testing. · Test 2 more times at least 48 hours apart if you do not have symptoms on the first day of testing. A negative test result indicates that the virus that causes COVID-19 was not detected in your sample. A negative result is presumptive, meaning it is not certain that you do not have COVID-19. You may still have COVID-19 and you may still be contagious. There is a higher chance of false negative results with antigen tests compared to laboratory-based tests such as PCR. If you test negative and continue to experience COVID-19-like symptoms, (e.g., fever, cough, and/or shortness of breath) you should seek follow up care with your health care provider.




If the control (C) line is not visible, the test is invalid. Re-test with a new swab and new test device. Next steps: If the test result is invalid, you need to retest with a new test kit after collecting a fresh sample. If the test result is still invalid upon retesting, contact Immunostics Inc. at 1-732-918-0770.
