Results and Accuracy
Flowflex COVID-19 Antigen Home Test
How to interpret the results?
Please refer to your package insert on how to use this test.
What do the two red lines on the cassette mean after I complete the test?
What does it mean if I have a positive test result?
A positive result means that it is very likely you have COVID-19 because proteins from the virus that causes COVID-19 were found in your sample. You should self-isolate from others and contact a healthcare provider for medical advice about your positive result.
What does it mean if I have a negative test result?
A negative test result indicates that antigens from the virus that causes COVID-19 were not detected in your sample. However, if you have symptoms of COVID-19, and your first test is negative, you should test again in 48 hours since antigen tests are not as sensitive as molecular tests. If you have a negative result, it does not rule out SARS-CoV-2 infection; you may still be infected and you may still infect others. It is important that you work with your healthcare provider to help you understand the next steps you should take.
What does it mean to have an invalid result?
An invalid result means the test was not able to tell if you have COVID-19 or not. If the test is invalid, a new swab should be used to collect a new nasal specimen and the test should be run again, using a new test cassette and extraction buffer tube. If the problem persists, call (800) 838-9502 for assistance. Customer Service hours are 5a.m. – 5 p.m. (PST), 7 days a week.
What is a false-positive and a false-negative test result?
How accurate is this test?
Clinical studies have shown that antigen tests more accurately determine whether you are infected with the virus that causes COVID-19 when taken multiple times across several days. Repeat testing improves test accuracy. This serial testing approach is recommended to minimize the risk of incorrect results. However, due to the lower sensitivity of antigen tests, there is a higher chance this test will give you a negative result when you have COVID-19 than a molecular test would.
Is the test result still valid if I see a pinkish color on the test strip after applying the sample to the test cassette sample well?
The package containing my Flowflex tests was left outside in freezing temperatures for a few hours – below the storage temps. Will it affect the tests performance, and should I throw the tests away ?
Our R&D Dept. has checked and confirmed that the FlowFlex 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 tests was left outside in very high temperatures for a few hours – above the storage temps. Will it affect the tests performance, and should I throw the tests away ?
Our R&D Dept. has checked and confirmed that the FlowFlex kits that were exposed to temperatures above average (up to 65 °C / 150 °F) for a few hours are still working. Make sure the entire kit is cooled back to room temperature and there is still a least 1/3 of an inch of buffer in the tube before the kit is used for the testing.
