Step 4: Visit Your Local Test Center

Email Confirmation

After completing your order, you will get an email confirmation which will include the three closest testing centers to your location, along with their contact information. Your location is based on the zip code for your home address in your Grassroots Labs Account.

Grassroots Labs uses Quest Diagnostics Patient Service Centers (PSC) to perform all in-person lab tests. All test center locations will be run and operated by Quest Diagnostics or their affiliate vendors. PLEASE DO NOT try to visit a testing center that is not Quest Diagnostics.

Email Confirmation Example

Having Your Tests Performed

Once you find your closest testing center, you may visit it to have your lab tests performed anytime during normal business hours. The business hours for each testing site can be found when searching for test centers on the Grassroots Labs app. Most testing centers do not require to make an appointment to have your lab tests performed, unless you are having a COVID-19 Antibodies test performed. 

If you would like to make an appointment to have your tests performed at a Quest Test Center, please view our How-to Video " Scheduling An Appointment for Lab Testing with Quest Diagnostics". Also note, if you choose to do this, you will begin to get marketing emails from Quest Diagnostics.

What To Bring To the Test Center

  1. Requisition / Lab Order - We recommend that all Grassroots Labs users take a copy of their requisition with them to the testing center. The "requisition" is the formal document showing the lab what tests you are having performed, and that you have already paid for your test. While having your requisition is not required, it can prevent some logistical problems at the testing center.

    To learn how to download and print your requisition, see our support article on Requisitions.
  2. Government Issued Photo ID - All users MUST have a government issued photo ID in order to have your lab tests performed. This is how the Lab company confirms your identity. A few examples include: driver's license, passport, or green card.

Remember to Prepare

Please remember to check and see if there are any additional preparation steps to having your testing completed. This would include fasting food or beverages, other than water, for 8 hours before your tests and drinking plenty of water. You can read the specific preparation steps and directions for each test, by viewing the test descriptions on the Grassroots Labs website. 

Visiting the Testing Center

When you visit the test center, follow these steps:

  • Sign in at the front desk
    • During COVID-19, test centers have a digital sign in station in each testing center with which to sign in and let the testing staff know you are there.
  • Hand the attendant your requisition
  • Wait to be called
  • Have your tests performed
  • Go home

If you have any problems while visiting the testing center, please jump on our website, via your smart phone, and chat with our customer support representatives. You may also call us at (888) 315-3265.

After your tests are performed, you can normally expect to be notified that your results are ready within 3-5 business days. You will receive an email from Grassroots Labs when your results are ready to view in the "Order History" section of your account profile on Grassroots Labs.
