Stay at DoubleTree

Discovery Health MD has partnered with our Dedicated Hotel Testing Site to offer you special room rates while receiving your COVID-19 test, located minutes away from Seattle-Tacoma International Airport (SEA)!


You can access your results by visiting our website and go to the upper right-hand corner where you will see an option to select ‘PORTALS’. Please select the drop-down and choose the appropriate portal method based on your testing.

We provide results from our high throughput partner laboratories.

Next-Day results will be processed and posted by or before midnight the following day.

Antigen testing results will be available about 30 minutes after testing.

There are no guarantees or refunds for turnaround times due to processing lab delays

Please note that Discovery Health MD has been approved as a trusted testing partner for Hawai’i. Our partner labs have not directly received approval, but if you test through us, those lab results have been approved by the State of Hawai’i.

Your lab results may have only the name of the laboratory where the specimen was processed. Even though the results may not explicitly name Discovery Health MD, these result formats have been approved by and are being accepted by the State of Hawai’i.

Our partner labs results portal may state that they are not an approved partner. If you have tested through Discovery Health MD, your test results have been approved by the State of Hawai’i.

The State of Hawai’i has stated that they will contact us if there are questions or concerns about the results tested through Discovery Health MD and have our direct contact information available. Upon your arrival to Hawai’i, an airport representative will be able to manually verify that your result is from us and that we are in fact on the list of Trusted Testing Partners.


Before your sample is collected, you will receive a notecard with a QR code that will direct you to our DHMD results portal.

We expect to have your results by or before midnight the following day after your appointment. Historically, our results come in the early evening, but we cannot make any guarantees. 

Commercial Clients:

Test results will be sent to employers and Discovery Health MD. Employees should contact their employer to get a copy of their results.


No, our Test-to-Fly program is only available to individuals traveling through airports in the Seattle-Tacoma area. We do offer testing to our neighbors in Canada traveling through airports in the Seattle-Tacoma area as well.


We have a robust protocol and risk management program, designed specifically for your organization’s needs. Please follow this link to learn more: Test-to-Work

Testing will occur in the central auditorium at SEA, located pre-security, on the mezzanine level above ticketing and the security checkpoints near Door 21.


First you will need to visit our bookings page, which can be found here: Test-To-Fly Booking

Once the testing appointments are scheduled, you will receive an email with a link to fill out the online consent and questionnaire. You will be asked if you have any current symptoms or recent exposure to someone with possible COVID-19. If you have symptoms, you should not test and should seek medical care. You will be asked to provide demographic information and answer some questions including your travel history in the past 60 days. This information will help with contact tracing efforts  if you or your party have a positive result.

It is very important your name matches your identification exactly.

On the testing day, your ID will be verified and our medical staff will assist you with obtaining the nasal swab specimen. These will be sent to one of our partner laboratories for processing.


Our testing process is highly adaptable to the needs of our commercial and remote clients. Please visit our Test-to-work page to learn more about how we can best serve your organization.

Upon booking, make sure to register on our DHMD results portal. On the day of the test, before your sample is collected, you’ll receive a notecard with a QR code that will direct you back to Discovery Health MD’s results portal where you will view your Determination Letter in digital PDF format. You may also access the Results Portal via our website, by selecting ‘Portals’ in the upper right-hand corner of the page.

We are not accepting or billing insurance for payment of any kind. 

The Washington State Office of the Insurance Commissioner FAQ states that insurance will cover testing and treatment for medically-necessary services, while our testing is meant to serve people looking for asymptomatic and travel testing. Travelers may contact their insurance company to find out whether they can be reimbursed for travel testing. We provide proof of payment receipt at the time of the test.
