A rapid antigen test is a medical device 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, here.
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.
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.
Yes! On/Go and On/Go One can be used to detect the antigen proteins from all major known COVID-19 variants of concern including Delta and Omicron. When new variants arise, we rigorously perform tests to ensure the variants do not affect the performance of the test.
On/Go and On/Go One can be found in many places. Visit our shop to get tests delivered to your home. You can also find our tests on Amazon and Walmart.com
Yes, On/Go 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. Major retailers of On/Go One will show the FSA eligibility on the store receipt as of mid-March. Your tests should also be reimbursable by private insurance.

The tests are very similar with slight differences. The On/Go One test requires 4 drops of solutions and 15 minutes until results. The On/Go test provides results in 10 minutes and only requires 3 drops of solutions. Please be sure to follow the step by step instructions within the app (or on the paper instructions) to make sure you are doing the proper steps for each test!
On/Go One is specially formulated to test both symptomatic and asymptomatic people with one test. The On/Go test is slightly faster but is intended to be used as a serial test; meaning you are required to take 2 tests within a 24--48-hour period. Serial testing is advantageous and the On/Go One can also be used serially if you want to be even more certain you are not likely transmitting the virus.
On/Go has different tests with specialized performance characteristics. We work with best in class manufacturers from around the world so you may see different made in locations. Our goal is to expand access to accurate, affordable tests and bring the best available tests to the US people!

You can download the On/Go app by searching “On/Go” in the Google Play or Apple App stores or by scanning the QR code on the box.
The On/Go app should be used to complete your test with confidence! Think of the On/Go app as your trusted side-kick. The app provides clear, illustrated step-by-step instructions from opening your test all the way through result interpretation, taking the guesswork out of testing and helping ensure your test and results are valid. By completing both On/Go and On/Go One tests with the On/Go app, you can quickly share your results with friends and keep all your results organized in a single place, allowing you to easily view the testing history of you and your loved ones. For new testers and experts alike, the On/Go app allows for an extremely easy way to test for COVID-19.
While you’re taking the test and following the illustrative instructions, you should not close the On/Go app. Think of it as a 10 minute break from scrolling.
Please make sure you are running the latest version of the app. First, uninstall the version of the app on your phone and then install the latest version. Search for On/Go in the Google Play or Apple App store and download the latest version. Older devices and operating systems may be incompatible with the On/Go application.
Please open the app again as soon as possible. If you are at a step that can be continued, you will be able to continue where you left off. If this is not the case, you will need to start a new test.
Once you apply your sample to the sample well, the app will begin a timer for either 10 minutes (On/Go) or 15 minutes (On/Go One). After the first timer is complete, your results are ready to be interpreted. You will have a few minutes to take a picture of your results, shown on the screen through another timer. If you wait longer than the allotted time, the results are not valid (and may provide false negative or false positive results) and you will need to start a new test.
The information you provide is kept in order to report to public health authorities, where appropriate. Per CDC guidelines, certain federal and state regulations mandate reporting of test results to appropriate agencies. Privacy is of utmost importance to us. All data is encrypted and not shared with any other third parties.
On/Go One is 98.2%* accurate with results in just 15 minutes. Please click here for more information and to read the product documentation.

That’s a great question! On/Go One is an authorized distributor brand name of the Flowflex COVID-19 Antigen Home Test. You can find On/Go referenced in footnote 4 of the EUA letter for Flowflex here.
Attention: On August 29, 2022, the FDA granted an additional 3-month shelf-life extension for On/Go COVID-19 Antigen Self-Tests (also known under CareStart COVID-19 Antigen Self-Test EUA letter). Please note, the expiration date for the tests is the last day of the labeled expiration month. To determine the new expiration date for your test, please refer to the attached document, organized by lot number. We will continue to apply to FDA for shelf-life extensions every three months based on our stability studies, and the new shelf-lives for our tests will apply to tests already produced as well as future production.
On/Go One tests already have a 12+ month shelf life.
These extensions occur because 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 again early in spring. We will continue to closely update this page as well as our website when the expiration date gets extended.
For those without symptoms, the On/Go test should be administered twice over two or three days, with 24-48 hours between tests.This On/Go test is also authorized for non-prescription home use with adult-collected nasal (nares) swab samples from individuals aged 2 years or older with symptoms of COVID-19 within the first 7 days of symptom onset.
On the other hand, On/Go One, our other test, is specially formulated to test both symptomatic and asymptomatic people with one test.
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.
That’s a great question! On/Go is an authorized distributor brand name of the CareStart COVID-19 Antigen Home Test. You can find On/Go referenced in footnote 5 of the EUA letter for CareStart.
Depending on the box you purchase, there will either be 2 or 20 tests (and swabs, caps, and vials) included. Besides the items in the box, all you need is a smartphone and you’re ready to take your test!
Testing yourself is easy, even if you’ve never completed a COVID-19 test before. All test contents are in the box--the only thing you need is a smartphone to download the On/Go app. Simply open up your app and you will be provided with real-time, 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."
Potential risks include:
Potential benefits include:
No! The On/Go 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 provided on the On/Go mobile app. While it might tickle, it should not hurt. If you feel pain, please stop the test and seek advice from a healthcare provider.
You’ll have your results quicker than you think. On/Go Self-Tests provide results in 10 minutes. You should check your results after 10 minutes and no longer than 15 minutes after sample application.
Depending on which test you purchased, there will be 1, 2, or 20 tests included in the box. Please be sure to read the description of the product so you know which you are getting as the instructions are slightly different for On/Go and On/Go One. Each test requires a vial, cap, swab, and test device, all included in the box. The only other thing you need is a smartphone to get started.
After completing all the steps on the On/Go app, your results will be interpreted as positive, negative or invalid.
A negative result (COVID-19 Not Detected) will show only a line next to the “C” on the test device but no other lines.
A positive result (COVID-19 Detected) will show a line next to the “C” on the test device AND a line next to the “T.” The line on the “T” 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.
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. If you’re looking for up to date information from the CDC and protocols, please visit our resources page: letsongo.com/resources.
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.
The unique barcode on your test device contains essential information to ensure test validity. In the event the barcode is not valid for any reason, you will be presented with a final screen indicating an invalid result. When you are prompted to take a photo of your test, it helps ensure that the test is valid and not expired.
You can dispose of all used test kit components and patient samples in your household trash.
As rules are constantly changing, we recommend looking up rules at the destination country website for the most up to date information. A great resource is: https://www.iatatravelcentre.com/world.php
Vaccines are great, but testing, like the On/Go Self-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.
No, your vaccine will not affect the results of the test. While the vaccines target the spike proteins of the virus, the On/Go test looks for the nucleocapsid protein.
