How to Schedule an Appointment With Quest Diagnostics
Quest makes appointments through their website, phone line, or in-person at a patient service center
Quest Diagnostics runs one of the largest networks of lab testing locations in the United States. To get lab work done, you schedule an appointment ahead of time rather than walk in. You can book through their online portal at quest.com, call their scheduling line, or visit a center directly. The method you choose depends on whether you know which tests you need and how soon you want to be seen.
Quest operates thousands of patient service centers across the country. Most appointments can be scheduled for the same day or within a few days. You do not need a referral from a doctor to make an appointment, though your doctor's order for specific tests will be required when you arrive.
Key Takeaways
- You can schedule a Quest appointment online at quest.com, by phone at 1-800-222-0446, or by walking into a patient service center.
- Quest accepts most insurance plans, and you should bring your insurance card and photo ID to your appointment.
- If your doctor ordered tests, bring the order or requisition form; if not, you can still get tested but will pay out-of-pocket.
- Most appointments take 15 to 30 minutes, and results are typically available within one to three business days depending on the test type.
Scheduling online through Quest's website
The Quest website at quest.com has a scheduling tool that lets you search for nearby locations, pick a date and time, and confirm your appointment. You enter your zip code or city to see available centers. The tool shows you which times have openings and lets you choose the one that works for you.
When you schedule online, you will create or log into a Quest account. You provide your name, date of birth, contact information, and insurance details if you have them. If you already know which tests you need—because your doctor ordered them or you are paying out-of-pocket—you can add those to your appointment request. After you confirm, Quest sends a confirmation email with your appointment time, location address, and what to bring.
Calling Quest to book by phone
Quest's scheduling phone line is 1-800-222-0446. A representative can search for available appointments at locations near you and book one over the phone. This method works well if you prefer to talk through your options or if you have questions about what tests you need.
When you call, have your zip code ready so the representative can find nearby centers. If you have insurance, have your card available. The representative will confirm your appointment details and send a confirmation to your email or phone number. You can also ask about parking, hours, or whether the center has any special instructions for your specific tests.
Walking in to a Quest patient service center
Quest patient service centers accept walk-ins at most locations, though appointment times are prioritized. If you walk in without scheduling ahead, you may wait longer than someone with a scheduled time. Some centers are busier than others, so wait times vary by location and time of day.
To find a center near you, use the location finder on quest.com or call 1-800-222-0446. If you walk in, bring your insurance card, photo ID, and any doctor's order for tests. The staff will check you in and let you know the wait time before you decide whether to stay or schedule an appointment for later.
What to bring to your Quest appointment
Bring a photo ID and your insurance card to every appointment. If your doctor ordered specific tests, bring the order or requisition form—this is a printed or electronic document from your doctor that lists which tests to run. Without it, Quest can still perform tests, but you will pay the full cost out-of-pocket.
If you are fasting for certain blood tests, do not eat or drink anything except water for the time period your doctor specified—usually 8 to 12 hours before your appointment. Wear loose, comfortable clothing that makes it straightforward to access your arm for blood draws. Arrive 10 to 15 minutes early so you have time to check in.
Insurance, payment, and test results
Quest accepts most major insurance plans. When you schedule or check in, provide your insurance information so Quest can bill your plan. You may have a copay, coinsurance, or deductible depending on your plan and the tests ordered. If you do not have insurance, Quest offers self-pay pricing, which varies by test.
Test results are usually available within one to three business days after your appointment. Some routine tests come back faster; more complex tests take longer. Quest sends results to your doctor and to your online Quest account. You can log into your account at quest.com to view results, or your doctor's office will contact you with them.
Rescheduling or canceling an appointment
If you need to change your appointment time, log into your Quest account on quest.com and select the option to reschedule, or call 1-800-222-0446. Most locations allow you to reschedule up to 24 hours before your appointment time. If you cancel within 24 hours, you may lose the appointment slot and have to book a new one.
If you miss an appointment without canceling, Quest may charge a no-show fee depending on your location and plan. If you know you cannot make it, cancel as soon as possible so the time slot opens for someone else.
Frequently Asked Questions
Do I need a doctor's order to get lab work at Quest?
No, but having one is important. If your doctor ordered tests, bring the order so Quest bills your insurance correctly and you pay only your copay or coinsurance. Without an order, you can still get tested, but you pay the full self-pay price out-of-pocket.
How long does a Quest appointment take?
Most appointments take 15 to 30 minutes from check-in to leaving. The actual blood draw or test takes only a few minutes; the rest is check-in paperwork and waiting. Complex tests or multiple draws may take longer.
Can I schedule an appointment for someone else?
Yes, you can schedule for a family member or dependent. When you book, provide their name, date of birth, and contact information. They will need to bring their photo ID and insurance card to the appointment.
What if I do not know which tests I need?
Contact your doctor's office and ask them to place an order for the tests you need. Once you have the order, bring it to Quest. If you do not have a doctor or do not want to wait, you can call Quest at 1-800-222-0446 and ask about self-pay testing options.
Can I get results before my doctor does?
Yes. Quest sends results to your online account as soon as they are ready, usually before your doctor's office receives them. You can log in and view your results, though your doctor may want to discuss them with you before you act on them.
