What is the difference between Antigen, Molecular, and Antibody tests?
There are different kinds of tests for the viruses that cause COVID-19 and the flu. Molecular tests detect genetic material from the virus. Antigen tests, such as the Flowflex Plus COVID-19 + Flu A/B Home Test, detect proteins from the virus. Due to the lower sensitivity of antigen tests, there is a higher chance this test will give you a false negative result when you have COVID-19 than a molecular test would.
Another type of test is an antibody test. A COVID-19 antibody test detects antibodies that have been produced by your immune system in response to a previous COVID-19 infection or vaccination. Antibody tests are not suitable for diagnosing an active COVID-19 infection.

How deep should I insert the swab into my nose?
Insert the swab ½ to ¾ inches inside your nostril. With children, the maximum depth of insertion into the nostril may be less than ¾ of an inch, and you may need to have a second person hold the child’s head while swabbing. Note: A false-negative result may occur if the nasal swab specimen is not properly collected.
Should I swab my left or right nostril?
Please use the swab to collect specimen from both of your nostrils to ensure sufficient sample collection to generate an accurate result.
For how long do I have to swab my nostril?
Firmly rub the swab in a circular motion around the inside wall of the nostril 5 times. Take approximately 15 seconds to collect the specimen. Be sure to collect any nasal drainage that may be present onto the swab. Repeat this in the other nostril.
What color should the solution be inside the extraction buffer tube?
The solution should be clear and colorless. If you receive a solution that has a yellow color, do not use this test kit. Please contact customer service at (800) 838-9502 for assistance. Customer Service hours are 8 a.m. – 8 p.m. (EST), 7 days a week.
After nasal specimen collection, how long do I need to swirl the nasal swab in the buffer tube?
Place the swab into the buffer tube and swirl for 30 seconds. Rotate the swab 5 times while squeezing the tube. Remove the swab while squeezing the tube to extract as much liquid as possible. Attach the dropper tip firmly onto the tube. Mix thoroughly by swirling or flicking the bottom of the tube. Then gently squeeze the tube and dispense 4 drops of solution into the Sample Well.
How many drops should I put in the cassette well? Can I put in all the buffer solution?
You should dispense 4 drops of the solution into the cassette Sample Well. Please do not overuse the buffer solution.
Where should I dispense the solution on the cassette?
You should dispense 4 drops of solution into the cassette Sample Well marked with an “S”.
The liquid in the little tube seems low, how can I tell if I have enough liquid to perform the test?
If the little tube contains approximately 0.28 inch or 7 mm of buffer solution or more, there is enough buffer solution to perform the test.
Is the yellowish color on the tip of my nasal swab normal?
Yes, discoloration of the swab tip is normal and due to UV exposure. The swab is safe to use and will have no impact on test performance.
I just put my swab into the little tube, but I am concerned because the liquid does not cover the entire swab tip. Is this okay?
If the little tube contains approximately 0.28 inch or 7 mm of buffer solution or more, there is enough buffer solution to perform the test, even if the entire swab tip is not covered.
I ran my test and applied 4 drops of the liquid to the test cassette, but I am concerned because the liquid did not cover the entire swab tip when I prepared the sample. Is this okay?
If you were able to apply 4 drops of liquid unto the test cassette sample well marked “S”, and you followed all the instructions on the product insert, then it is fine. The entire swab tip does not need to be covered.
I performed the test according to the instructions, but when I tried to squeeze 4 drops out of the little liquid bottle, there was just enough liquid for 3 drops. Is my test result valid?
For the test to provide an accurate result, you must apply 4 drops of liquid unto the test cassette sample well, the one marked with an “S”. If your tube contained only enough liquid for 3 drops, you must repeat the test with a new cassette and a newly collected specimen sample.

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 and any other line or multiple lines, no matter how faint, at “CoV”, “A” and/or “B” 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?
What does it mean if I have a negative test result?
What does it mean to have an invalid result?
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.
How accurate is this test?
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?
A pinkish background color on the test strip will not affect the result of your test.
