About the RapidReturn COVID-19 Test Kit

CityHealth's RapidReturn Test Kit is designed for US travelers returning home from international travel. It is convenient, easy to use, and fits perfectly in your carry-on luggage.

Before you leave home, purchase your kit and pack it in your carry-on luggage. To take your return test, scan the QR code on the test or log on to cityhealth.com/intlkit within 24 hours before your scheduled return flight. No appointment needed - testing specialists are standing by 24 hours a day, 7 days a week.

Tip: Use the contact information you would like your results sent to. For example, use your cell phone number and an email address that you check while traveling instead of your office number and work email.

Once you have activated your kit, a testing specialist will be with you shortly to help you through the easy sample collection process.

Once your sample is collected, you will test it using the testing solution provided. This takes about 10 minutes. A testing specialist will view the result and tell you if you are COVID positive or negative.

When the test is over, you will be sent a link via a secure email and text message to view and download your results. As a security feature, you’ll need to enter your name and date of birth to view your results.

This is a Rapid Antigen test. Your sample is collected via a self-administered nasal swab inserted about ¾” inside each nostril.

Results of this test are approved for re-entry to the United States.

Please allow at least 15 minutes for your testing appointment.


It will take about 10 minutes for the testing solution to return a result. Your official Digital Health Certificate will be sent to you as soon as it's generated, usually within 2-3 minutes of your appointment. In rare cases, it may take up to 5 hours for results to be delivered.

Each Kit contains 2 tests and one activation code. One test is a spare, in case of inconclusive results on the first test. 

Each test contains a sterile swab, pre-filled tube of testing reagent, and a testing device. Each Kit has a unique activation code to identify your results.

Note that there are enough supplies for one Kit per person. Two people cannot share one RapidReturn Kit. 

Purchase one Kit per traveler.


The testing specialist will ask to see your passport before the test begins to confirm your identity, required to issue a Digital Health Certificate.


If you do not have your passport handy, a US-issued driver’s license is also acceptable.

Pre-travel COVID tests must be taken within 1 day of your planned departure.
