The hours of operation for each parexel patient service center are listed on the details page for each location. Please note: Some services, such as drug testing, are only available during certain hours. Please check the location details page prior to scheduling your appointment or visiting locations..

To schedule an appointment, go to our website page and search for the patient service center nearest you.

• Completing all of the check-in information before you get to a parexel patient service center saves you time when you arrive.
• PreCheck allows you to choose a time of service that is convenient for you. We do our very best to honor your reserved visit time.
• The PreCheck process allows you to securely enter all the information we need to perform your lab services, and review and approve your data before you arrive.

We request that you arrive 15 minutes before your scheduled time. However, if you are early and we have earlier times available, we can see you sooner.  If you arrive later than your appointment time, you will have the flexibility to choose the next available service time

You can modify a previously scheduled appointment by contacting support. Be sure to have your confirmation number available.

No! Once you go through the PreCheck process the first time and enter your health coverage and contact information, we’ll remember you as a known patient. You will then skip straight through the screens to the summary page; and from there make any necessary edits, or accept and receive your confirmation. After your initial use, it gets easier and faster.
