The Flowflex COVID-19 Antigen Home Test is a rapid test for the detection of SARS-CoV-2 antigens in anterior nasal

specimens. It is intended for self-testing use. For use under an Emergency Use Authorization (EUA) only.

This test uses a nasal swab sample to determine the presence or absence of COVID-19 antigens in nasal samples. For a demonstration on how this test works, watch the instructional video.

Serial testing is a process in which a user must test themselves twice within a two-to-three-day period. The Flowflex

COVID-19 Antigen Home Test has been authorized for use as a single test by individuals with or without symptoms.

This test is authorized for nonprescription home use with self-collected (unobserved) direct anterior nasal (NS) swab

specimens from individuals aged 14 years and older or with adult-collected anterior NS samples from individuals aged

2 years or older.

This test is intended for individuals with or without symptoms or other epidemiological reasons to suspect COVID-19.

This test is available in 2-test, 5-test, and 25-test packages.

Please do not swab your throat/ear. Please only swab your nose to collect samples and follow instructions on the package insert.

Please only use the swab that is provided with the test. Contact customer service at (800) 838-9502 for assistance.

Customer Service hours are 8 a.m. to 5 p.m. (Pacific Time), Monday - Friday.

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

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

Please use the swab to collect specimens from both of your nostrils to ensure sufficient sample collection to generate an accurate result.

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 on the swab. Repeat this in the other nostril.

14. The test cassette, extraction buffer tube, nasal swab, or tube holder is missing from the test package. What should I do?

Please contact customer service.

Monday - Friday.

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.

You should dispense 4 drops of solution into the cassette sample well. Please do not overuse the buffer solution.

You should dispense 4 drops of solution into the cassette Sample Well marked with an “S”

Results are available in 15 minutes.

No, the nasal swab is not sharp, and it should not hurt. Sometimes the swab can feel slightly uncomfortable. If you feel pain, please stop the test and seek advice from your healthcare provider.

Do not use this test on children under two years of age. Do not use this test on anyone who is prone to nosebleeds or has had facial injuries or head injuries/surgery in the past six months.

Potential risks include:

• Possible discomfort during sample collection.

• Possible incorrect test results (see Result Interpretation section).

Potential benefits include:

• The results, along with other information, can help you and your healthcare provider make informed

decisions about your care.

• The results of this test may help limit the spread of COVID-19 to your family and others in your community.

23. 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?

Pinkish background color on the test strip will not affect the result of your test.

24. What is the difference between Antigen, Molecular, and Antibody tests?

There are different kinds of tests for COVID-19. Molecular tests (also known as PCR tests) detect genetic material from

the virus. Antigen tests, such as the Flowflex COVID-19 Antigen Home Test detect proteins from the virus. Antigen tests

are very specific for the COVID-19 virus but are not as sensitive as molecular tests. This means that a positive result is

highly accurate, but a negative result does not rule out infection. If your test result is negative, you should discuss with

your healthcare provider whether an additional molecular test is necessary and if you should continue isolating at home.

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.

If both the control line (C) and test line (T) appear, even if the line on the test line (T) is very faint, this means that you

have a positive test result because antigens from COVID-19 were detected, and it is very likely you currently have

COVID-19. Please refer to the package insert for more information.

A positive test result means that antigens from COVID-19 were detected and it is very likely you currently have

COVID-19. There is a very small chance that this test can give a positive result that is wrong (a false-positive result).

If you test positive you should self-isolate at home per CDC recommendations to stop spreading the virus to others.

Please consult the CDC recommendations regarding self-isolation at Seek follow-up care with

your healthcare provider immediately. Your healthcare provider will work with you to determine how best to care for you based on your test result(s), medical history, and symptoms.

An invalid test result indicates that not enough specimen volume was collected or incorrect test operation is the likely reasons for an invalid result. Please review the instructions again and repeat the test with a new cassette.

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 performance of the Flowflex COVID-19 Antigen Home Test was established in an all-comers clinical study

conducted between March 2021 and May 2021 with 172 nasal swabs self-collected or pair-collected by another

study participant from 108 individual symptomatic patients (within 7 days of onset) suspected of COVID-19 and 64

asymptomatic patients. All subjects were screened for the presence or absence of COVID-19 symptoms within two

weeks of study enrollment. The Flowflex COVID-19 Antigen Home Test was compared to an FDA authorized molecular

SARS-CoV-2 test. The Flowflex COVID-19 Antigen Home Test correctly identified 93% of positive specimens and 100% of negative specimens.
