How to read your results

COVID-19 Detected (Positive)

One purple-colored line next to the “C” and one blue-colored line next to “T” indicates COVID-19 positive result. (Look very closely! The color intensity in the test region will vary. Any faint coloured line in the test region should be considered as positive.)

COVID-19 Not Detected (Negative)

One purple-coloured line next to “C” indicated a negative result.


Invalid barcode or absence of a purple-coloured line next to “C”.

What’s in the box?

COVID basics

What is a rapid antigen test?

A rapid antigen test is a tool that identifies proteins of the virus, called antigens. A positive test result will occur when the virus is “live” and replicating, meaning the test taker is able to transmit it to other people. Because of this, rapid antigen tests are a helpful tool to figure out if you’re actually at risk of spreading COVID-19. Plus, unlike PCR tests which can take up to 3 days to get results, rapid antigen tests, like On/Go, provide results in as little as 10 minutes because all the pieces needed for analysis are in the test itself! Learn more about what an antigen test is on our blog,

Who should use an antigen test?

Individuals aged 14 or older can perform the test directly. Adults can help perform the test for children aged 2 or older. The test can be used for individuals with or without symptoms, as often as you’d like.

What are common symptoms of COVID-19?

Symptoms of COVID-19 may appear 2-14 days after exposure and may include fever, cough, shortness of breath, fatigue, muscle or body aches, headache, loss of taste or smell, sore throat, congestion, or a runny nose, nausea or vomiting and diarrhea. It is also possible for someone infected with COVID-19 to have no symptoms.

When does my test expire? Why does my expiration date seem so soon?

Currently, the test expires on the last date of the month printed on your box (i.e. January 2022 means January 31, 2022). However, with medical products under EUA, such as On/Go, the FDA, after close studies, grants rolling expiration extensions. We expect the expiration date to be extended before the end of January and another expiration extension  again early in spring. We will continue to closely update this page as well as our website when the expiration date gets extended

Does this test work with COVID-19 variants?

Yes! This test can be used to detect the antigen proteins from all major known COVID-19 variants of concern including Delta. When new variants arise, we rigorously perform tests to ensure the variants do not affect the performance of the test. 

Can you pay for this test with an FSA or HSA?

Yes, this test is FSA eligible. COVID tests are approved medical expenses under IRS rules.  Save your receipts for your taxes and/or contact your program administrator for more details.

Taking the test

How do I test myself?

Testing yourself is easy, even if you’ve never completed a COVID-19 test before. All test contents are in the box. Simply read through your illustrated step-by-step instructions, which are also included in every test box. You’ll have your results in no time. It’s as easy as “tap, swab, snap.”

What are the known and potential risks and benefits of the test?

Potential risks include:

  • Possible discomfort or other complications that can happen during sample collection
  • Possible incorrect test result

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
Does the test hurt?

No! This test uses a lower nasal swab, not the “brain-tickling” swab you ​​may associate with COVID-19 tests. You only need to insert the swab less than ¾ of an inch into your nose, which can be seen by following the simple instructions. While it might tickle, it should not hurt. If you feel pain, please stop the test and seek advice from a healthcare provider. 

How long does it take to get results?

You’ll have your results quicker than you think. This test provides results in 10 minutes. You should check your results after 10 minutes and no longer than 15 minutes after sample application. 

The picture in Step 2 of the instructions looks like the tray requires the removal of a cover. If I don’t have a cover, is something wrong?

Everything is ok. Tests sealed on the box flap have individually sealed components (swab, test, vial) in the tray. No cover on the tray is necessary.

How long should people wait between taking these tests?

The tests should be administered twice over two or three days, with 24-48 hours between tests.


How do I know if I'm positive or negative?

After completing your test your results will be interpreted as positive, negative or invalid. 

  • A negative result (COVID-19 Not Detected) will show only a pink or red line next to the “C” on the test device but no other lines.
  • A positive result (COVID-19 Detected) will show a pink or red line next to the “C” on the test device AND a purple line next to the “T.” The purple line may be very faint.
  • An invalid result can occur either due to an invalid barcode or the absence of a colored line next to the “C” on the test device.
What happens if I get a positive result?

If you get a positive test result, you should self-isolate at home and avoid contact with others, per CDC recommendations, and follow care instructions from your healthcare provider and local health department. There is a very small chance that this test can give a positive result that is wrong (a false positive result). 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. If you have an emergency warning sign (including trouble breathing), call 911.

What happens if I get a negative 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.
  • 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 do I do if I receive an invalid test result?

In some rare cases, you may get an invalid result. If this happens, you will need to retest with a new test or consult a healthcare professional. If you have symptoms, you should self-isolate at home and avoid contact with others prior to re-testing. 

How do I dispose of my test?

You can dispose of all used test kit components and patient samples in your household trash.

Testing, vaccines & variants

Do I still need to get tested if I'm vaccinated?

Vaccines are great, but testing, like this test, will remain a key tool to keep communities safe and defeat COVID-19 as fast as possible. Independent of vaccinations, testing is a useful snapshot of the spread of the disease in communities.

Will vaccines cause a false positive?

No, your vaccine will not affect the results of the test. While the vaccines target the spike proteins of the virus, this test looks for the nucleocapsid protein.
