Results and Accuracy
Flowflex Plus RSV + Flu A/B + COVID Home Test
How to interpret the results?
Please refer to the Quick Reference Instructions on how to use this test.
What do the red lines on the cassette mean after I complete the test?
If the control (Ctl) line is visible on both strips and any other line or multiple lines, no matter how faint, at “R”, “A”, “B”, and/or “CoV” appear, the test is positive for that virus. Please refer to the Quick Reference Instructions for more information.
What does it mean if I have a positive test result?
A positive test result means that any one, or multiple, of the viruses detected by this test were also detected in your sample. It is very likely that you have the respective RSV, COVID-19, or influenza infection(s) and are contagious. You should self-isolate following local guidelines. Please contact your physician or healthcare provider to discuss your tests results and follow-up care. In rare instances, individuals may also have co-infections with other bacteria or viruses that this test is not designed to detect. This means that the virus detected by this test may not be the definitive or the only cause of your disease. There is a very small chance that this test can give you a positive result that is incorrect (a false positive).
What does it mean if I have a negative test result?
If both Control (Ctl) lines are visible, but the Test (R/A/B/CoV) line(s) is not visible, the test is negative. The RSV, Flu A, Flu B, or COVID-19 virus have not been detected. If respiratory symptoms persist, seek follow-up care with a healthcare provider.
What does it mean to have an invalid result?
If the Control (Ctl) line is not visible on either or both test strips, even if any test line is visible in the result window, the test is invalid. Re-test with a new test kit and sample. If the problem persists, call (800) 838-9502 for assistance.
What is a false-positive and a false-negative test result?
A false positive is a test result that indicates a person has a specific disease or condition when the person actually does not have the disease or condition. A false-negative test result indicates a person does not have a specific disease or condition when the person actually does have the disease or condition. Incorrect specimen collection and sample preparation can result in false-negative and false-positive test results. Therefore, before you begin the test, it is very important to read the package insert provided in the test package and follow the instructions.

The package containing my Flowflex Plus Flu A/B + COVID Home Test was left outside in freezing temperatures for a few hours – below the storage temperature listed on the kit box. Will it affect the tests’ performance, and should I throw the test away?
Our R&D Dept. has checked and confirmed that the Flowflex Plus RSV + Flu A/B + COVID Home Test kits that were frozen are still working. Make sure the entire kit is back to room temperature and that the extraction buffer is thawed and back to liquid solution form before the kit is used for the testing.
The package containing my Flowflex Plus Flu A/B + COVID Home Test was left outside in very high temperatures for a few hours – above the storage temperature listed on the kit box. Will it affect the tests’ performance, and should I throw the test away?
Our R&D Dept. has checked and confirmed that the Flowflex Plus RSV + Flu A/B + COVID Home Test kits that were exposed to temperatures above average (up to 55 °C / 131 °F) for a few hours are still working. Make sure the entire kit is cooled back to room temperature and there are still at least 3 drops of extracted samples for testing.
