SPECIMEN COLLECTION

SELF COLLECTION

COLLECTION BY AN ADULT

A nasal swab sample can be self-collected by an individual aged 14 years and older.
Children aged 2 to 13 years should be tested by an adult.

TEST PROCEDURE

Unscrew the dropper cap from the extraction buffer tube. Place the tube in the tube holder.

Open the swab packaging at the stick end, not the swab end. Do not touch the swab head.

Gently insert the entire absorbent tip of the swab head into 1 nostril (½ to ¾ of an inch).
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 to hold the child’s head while swabbing.
Note: A false-negative result may occur if the nasal swab specimen is not properly collected.

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.

Remove the swab from the nostril and immediately place it into the extraction buffer tube.
Note Test samples immediately after collection, and no more than one hour after the swab is added to the reagent solution if stored at room temperature.

Immediately place the swab into the tube and swirl for 30 seconds.
Note: A false-negative result may occur if the swab is not swirled for at least 30 seconds.

Rotate the swab 5 times while squeezing the tube.
Note: A false-negative result may occur if the swab is not rotated five times.

Remove the swab while squeezing the tube.
Dispose of the swab in the trash.

Screw the dropper cap firmly onto the tube.
Mix thoroughly by swirling or flicking the bottom of the tube. Remove the small cap from the dropper tip.

Gently squeeze the tube and dispense 4 drops of solution into the Sample Well. Dispose of the tube in the trash.
Note: A false negative or invalid result may occur if less than 4 drops of fluid are added to the Sample Well.

Set the timer for 15 minutes. Results should be read at 15 minutes.
Do not read after 30 minutes. Dispose of the test cassette in the trash.
Note: A false negative or false positive result may occur if the test result is read before 15 minutes or after 30 minutes.

RESULT INTERPRETATION

Only the control line (C) and no test line (T) appear. This means that no SARS- CoV-2 antigen was detected.
A negative test result indicates no antigens for COVID-19 were detected. It is possible for this test to give a negative result that is incorrect (false negative)  in some people with OVID-19 and negative results are presumptive and may need to be confirmed with a molecular test. This means that you could possibly still have COVID-19 even though the test is negative. If you test negative and continue to experience symptoms or symptoms become more severe, please consult your healthcare provider. It is important that you work with your healthcare provider to help you understand the next steps you should take.

Both the control line (C) and test line (T) appears. This means that the SARS- CoV-2 antigen was detected.
NOTE: Any faint line in the test line region (T) should be considered positive. A positive test result means that antigens from COVID-19 were detected and it is very likely you currently have COVID-19 disease. Self- isolate to avoid spreading the virus to other people and consult your healthcare provider as soon as possible. Your healthcare provider will work with you to determine how best to care for you.

Control line (C) fails to appear. Not enough specimen volume or incorrect operations are the likely reasons for an invalid result. Review the instructions again and repeat the test with a new cassette. If the problem persists, call (800) 8389502 for assistance.

INTENDED USE

The Flowflex COVID-19 Antigen Home Test is a lateral flow chromatographic immunoassay intended for the qualitative detection of the nucleocapsid protein antigen from  SARS-CoV-2 in anterior nasal swab specimens directly from individuals within 7 days of symptom onset or without symptoms or other epidemiological reasons to suspect  COVID-19 infection. This test it authorized for non-prescription home use with self-collected anterior nasal swab specimens directly from individuals aged 14 years and older or with adult-collected anterior nasal samples directly from individuals aged 2 years or older. The Flowflex COVID-19 Antigen Home Test does not differentiate between  SARS-CoV and SARS-CoV-2.
Results are for the identification of SARS-CoV-2 nucleocapsid protein antigen. This antigen is generally found in anterior nasal swabs during the acute phase of infection. Positive results indicate the presence of viral antigens, but clinical correlation with patient history and other diagnostic information is necessary to determine infection status. Po positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of the disease.
Individuals who test positive should self-isolate and consult their healthcare provider as additional testing may be necessary and for public health reporting.
Negative results are presumptive and confirmation with a molecular assay, if necessary, for patient management may be performed. Negative results do not rule out SARS-CoV- 2 infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions. Negative results should be considered in the context of an individual’s recent exposures, history, and the presence of clinical signs and symptoms consistent with COVID-19.
Individuals should provide all results obtained with this product to their healthcare provider for public health reporting. Healthcare providers will report all test results they receive from individuals who use the authorized product to relevant public health authorities in accordance with local, state, and federal requirements using appropriate LOINC  and SNOMED codes, as defined by the Laboratory In Vitro Diagnostics (LIVD) Test Code Mapping for SARS-CoV-2 Tests provided by CDC. The Flowflex COVID-19  Antigen Home Test is intended for self-use or lays user testing in a non-laboratory setting. The Flowflex COVID-19 Antigen Home Test is only for use under the Food and Drug Administration’s Emergency Use Authorization.

WHAT IS THE DIFFERENCE BETWEEN AN ANTIGEN AND A MOLECULAR TEST?

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.

HOW ACCURATE IS THIS TEST?

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  symptomatic 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.

WHAT IF YOU TEST POSITIVE?

A positive test result means that antigens from COVID-19 were detected and it is very likely you currently have COVID-19 disease. 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 www.cdc.gov/coronavirus. 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) along with your medical history, and your symptoms.

WHAT IF YOU TEST NEGATIVE?

A negative test result indicates no antigens for COVID-19 were detected. It is possible for this test to give a negative result that is incorrect (false negative) in some people with  COVID-19 and negative results are presumptive and may need to be confirmed with a molecular test. This means that you could possibly still have COVID-19 even though the test is negative. If you test negative and continue to experience symptoms of fever, cough, and/or shortness of breath you should seek follow-up care with your healthcare provider immediately. Your healthcare provider may suggest you need another test to determine if you have contracted the virus causing COVID-19. If you are concerned about your COVID-19 infection status after testing or think you may need follow-up testing, please contact your healthcare provider.

IMPORTANT

This test is intended to be used as an aid in the clinical diagnosis of a current COVID-19 infection. Do not use this test as the only guide to manage your illness. Please consult your healthcare provider if your symptoms persist or become more severe, or if you are concerned at any time.
Individuals should provide all results obtained with this product to their healthcare provider for public health reporting.
