FACT SHEET FOR INDIVIDUALS
Intrivo Diagnostics, Inc.
on/go™ COVID-19 Antigen Self-Test
August 2, 2021
Coronavirus
Disease 2019
(COVID-19)

You are provided this Fact Sheet because you obtained the on/ go™ COVID-19 Antigen Self-Test for testing yourself or dependents for the proteins from the virus that causes
COVID-19. The intended use of this test is for testing twice over two or three days with at least 24 hours and no more than 48 hours between tests.
This Fact Sheet contains information to help you understand the risks and benefits of using this test for the detection of proteins from the virus that causes COVID-19. After reading this Fact Sheet, if you have questions or would like to discuss the information provided, please talk to your healthcare provider.

What is COVID-19?
COVID-19 is caused by the SARS-CoV-2 virus which is a new virus in humans causing a contagious respiratory illness.
COVID-19 can present with a mild to severe illness, although some people infected with COVID-19 may have no symptoms at all. Older adults and people of any age who have underlying medical conditions have a higher risk of severe illness from COVID-19. Serious outcomes of COVID-19 include hospitalization and death. The SARS-CoV-2 virus can be spread to others not just while one is sick, but even before a person shows signs or symptoms of being sick (e.g., fever, coughing, difficulty breathing, etc.). A full list of symptoms of COVID-19 can be found at the following link: https://www.cdc.gov/coronavirus/2019-ncov/symptoms-testing/symptoms.html.
What is the on/go™ COVID-19 Antigen Self-Test? The on/ go™ COVID-19 Antigen Self-Test is a type of test called an antigen test. Antigen tests are designed to detect proteins from the virus that causes COVID-19 in anterior nasal swabs.
The on/go™ COVID-19 Antigen Self-Test is intended for the qualitative detection of the nucleocapsid protein antigen from SARS-CoV-2 from individuals with or without symptoms tested twice over two or three days with at least 24 hours and no more than 48 hours between tests.

What are the known and potential risks and benefits of the test?
Potential risks include:

Possible discomfort or other complications can happen during sample collection.
Possible incorrect test result (see below for more information).
Potential benefits include:
The results, along with other information, can help you and your healthcare provider make informed recommendations about your care.
The results of this test may help limit the potential spread of COVID-19 to your family and others in your community.

What does it mean if I have a positive test result?
If you have a positive test result, it is very likely that you have COVID-19 because proteins from the virus that causes COVID-19 were found in your sample. Therefore, it is also
likely that you may be placed in isolation to avoid spreading the virus to others. 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 with the on/go™ COVID-19 Antigen Self-Test you should self-isolate and seek follow-up care with your healthcare provider as additional testing may be necessary. Your healthcare provider as additional testing may be necessary. 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 does it mean if I have a negative test result?
A negative test result means that proteins from the virus that causes COVID-19 were not found in your sample. It is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID-19. This means you could possibly still have COVID-19 even though the test is negative. The amount of antigen in a sample may decrease the longer you have symptoms of infection. In symptomatic people, specimens collected after you have had symptoms for more than five days may be more likely to be negative compared to a molecular assay.

Where can I go for updates and more information?
The most up-to-date information on COVID-19 is available at the CDC General webpage: https://www.cdc.gov/COVID19. In addition, please also contact your healthcare provider with any questions/concerns.
If you test negative and continue to experience COVID-19 like symptoms of fever, cough, and/or shortness of breath you should seek follow-up care with your healthcare provider. For example, 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.

What is serial testing?
Serial testing is when a single person is tested for COVID-19 more than once. Because antigen tests are less sensitive than other COVID-19 tests and false results may occur, repeated testing may identify more individuals with COVID-19 infection than a single test. By repeating testing, it may be possible to more quickly identify cases of COVID-19 infection and reduce the spread of infection. Additional testing with molecular COVID-19 test may be necessary, depending on your individual risk factors and test results.
It is important that you work with your healthcare provider to help you understand the next steps you should take.

What are the differences between antigen tests and other COVID-19 tests?
There are different kinds of tests for diagnosing COVID-19.
Molecular tests (also known as PCR tests) detect genetic material from the virus. Antigen tests detect proteins from the virus. Antigen tests are very specific for the 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 would help with your care, and when you should discontinue home isolation. If you will not have an additional test to determine if you are contagious, the CDC currently recommends that you should stay home until three things have happened:

If you will not have an additional test to determine if you are contagious, the CDC currently recommends that you should stay home until three things have happened:
AND

You have had no fever for at least 24 hours (that is one full day of no fever without the use of medicine that reduces fevers)
Other symptoms of COVID-19 are improving (for example, when your cough or shortness of breath has improved) Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation
AND**
At least 10 days have passed since your symptoms first appeared.

Is this test FDA-approved or cleared?
No. This test is not yet approved or cleared by the United States FDA. FDA may issue an Emergency Use Authorization (EUA) when certain criteria are met, which includes that there are no adequate, approved, available alternatives. The EUA for this test is supported by the Secretary of Health and Human Service’s (HHS’s) declaration that circumstances exist to j ustify the emergency use of in vitro diagnostics for the detection and/or diagnosis of the virus causes COVID-19. This EUA will remain
in effect (meaning this test can be used) for the duration of the COVID-19 declaration justifying emergency of IVDs, unless it is terminated or authorization is revoked by FDA (after which the test may no longer be used).

What are the approved alternatives?
There are no approved available alternative antigen tests. Any tests that have received full marketing status (e.g., cleared, approved), as opposed to a EUA, by FDA can be found by searching the medical device databases here:
https://www.fda.gov/medical-devices/device-advice-comprehensiveregulatory- assistance/medical-device-databases. A cleared or approved test should be used instead of a test made available under a EUA, when appropriate and available. FDA has issued EUAs for other tests that can be found at:
