If I purchased multiple tests, do I have to schedule separate appointments?

No, multiple tests purchased can be scheduled for an appointment at the same time.

Do I need separate appointments for the tests my doctor ordered and the tests I purchase from questhealth.com?

Most of the time, you can have your sample collected for multiple orders within one appointment. There are a few tests (such as glucose testing) that may require a separate appointment due to requirements such as fasting or the need for a longer appointment time.

How do I change or cancel my appointment?

If you have your appointment confirmation email, you can reschedule or cancel your appointment via the link in the email.

What do I need to know before I arrive at a Quest Diagnostics Patient Service Center?

Please be aware that when you visit a Quest Diagnostics Patient Service Center:

  • Scheduled appointments are strongly encouraged and will receive priority. If you walk in, you will have to wait for the next available opening. Please arrive and check in 10 minutes before your appointment time. If you check in more than 10 minutes late for your appointment, you will be served as a walk-in.
  • If you walk in, you will have to wait for the next available opening.
  • Masks or face coverings are required while in a patient service center, even if you got a COVID-19 vaccination.

Note: If you have severe symptoms such as a high-grade fever of 102° F that has lasted for 48 hours or severe and constant shortness of breath, please see your doctor before making an appointment.

Protecting your health is more important than ever. Quest Diagnostics Peace of Mind program makes it easier and safer to access the routine testing you need. For more information, click here.

Are there any dietary restrictions I need to be aware of before I get tested?

Some blood tests require that you refrain from eating or drinking anything but water (fasting) prior to having your blood drawn. Fasting or diet requirements will be detailed in your confirmation email.

What is fasting?

Fasting is where you do not eat or drink anything except water before having a lab test – usually for 8 hours or more. If you have prescription medications, you should continue taking them during this time. Please visit www.QuestDiagnostics.com/patients/get-tested/prepare/fasting for additional fasting information.

Do I really have to fast? What if I didn't?

For tests that require fasting, it provides the most reliable results. If you did not fast and want us to perform the test anyway, we'll note it on the report for reference.

How do I check in when I arrive?

Sign in using the electronic kiosk or, if not available, sign the clipboard at the front desk. Please be prepared to present a valid photo ID. Be sure to mark the reason for your visit when signing in. Additionally, please bring your order number or a copy of your order details.
