How to Schedule an Appointment on Quest Diagnostics' Website

How to book a lab appointment through www.questdiagnostics.com

You can schedule a lab appointment on Quest Diagnostics' website by going to www.questdiagnostics.com, clicking the "Schedule an Appointment" button, and entering your zip code to find nearby locations. The site will show you available time slots at each lab, and you can pick the one that works for you. You'll need to provide your name, date of birth, phone number, and insurance information (if you have it) to complete the booking.

Quest Diagnostics is one of the largest lab testing networks in the United States, with thousands of patient service centers across the country. Most appointments can be booked online without calling, and you'll receive a confirmation email with your appointment details, location address, and what to bring.

Key Takeaways

• Visit www.questdiagnostics.com and use the "Schedule an Appointment" tool to find labs near you by entering your zip code.
• You can book most appointments online without a doctor's order, though some tests require one — the website will tell you which ones.
• Bring a photo ID and insurance card to your appointment; if you don't have insurance, Quest will provide pricing information upfront.
• You can reschedule or cancel your appointment through the same website up until a few hours before your scheduled time.
• If the website is not working or you prefer to book by phone, call 1-866-QUEST-99 (1-866-787-8399) to speak with a representative.

What information you need to have ready

Before you start booking, gather your insurance card if you have one. Quest will ask for your member ID and group number. If you don't have insurance, you can still book an appointment — Quest will show you the cost of your test before you confirm.

You'll also need a valid photo ID to bring to your appointment. A driver's license, passport, or state ID all work. If you're booking for someone else (like a child or dependent), you'll need their date of birth and your relationship to them.

If your doctor ordered a specific test, have that order handy. Some tests require a doctor's order to be valid, and the website will let you know during booking whether yours does. If you don't have an order and need one, Quest can sometimes help you find a doctor through their site, though this varies by state.

Finding a location and time slot

After you enter your zip code on the Quest website, you'll see a list of nearby labs with their addresses, hours, and available appointment times. The site shows you time slots for the next several days, usually starting from the next business day. Peak times (early morning and lunch hours) often fill up faster than afternoon slots.

Some locations are inside retail stores like Walgreens or CVS, while others are standalone Quest patient service centers. The website shows you which type each location is. If you need a specific type of test that requires special equipment, the site will only show you locations that offer it.

You can also filter results by distance, hours of operation, or whether the location offers walk-in appointments. Walk-ins are available at most Quest locations but may have longer wait times than scheduled appointments.

Completing your online booking

Once you've chosen a location and time, the website will ask you to create or log into a Quest account. If you don't have one, you can create it with your email address and a password. This account stores your appointment history and test results, so you can view them online later.

Next, you'll enter your personal information: full name, date of birth, phone number, and address. Then you'll provide your insurance details if you have coverage. If you're uninsured, Quest will show you the cost of your test at that point. You can review the total before you confirm the appointment.

After you submit, you'll receive a confirmation email with your appointment details, a barcode or confirmation number, and directions to the lab. Save this email or take a screenshot — you'll need to show the confirmation number when you arrive.

What to expect when you arrive

Arrive 10 to 15 minutes early to allow time for check-in. Bring your photo ID, insurance card, and your confirmation number or email. If you printed your order from a doctor, bring that too. The staff will verify your information, confirm which tests you're having done, and answer any questions about fasting or other preparation.

Most lab visits take 15 to 30 minutes from check-in to leaving. A phlebotomist (the person who draws blood) will call you back when they're ready. If you're nervous about needles or have had trouble with blood draws in the past, let the staff know — they can help make it easier.

After your test, you can usually view your results online through your Quest account within 24 to 48 hours. Your doctor will also receive them if they ordered the test. Some results take longer depending on the type of test.

Rescheduling or canceling your appointment

If you need to change your appointment time or date, log into your Quest account on www.questdiagnostics.com and go to "My Appointments." You can reschedule to a different time or location, or cancel entirely. Most changes can be made up to a few hours before your appointment time.

If you can't reschedule online or your appointment is very soon, call 1-866-QUEST-99 (1-866-787-8399). A representative can help you move your appointment or cancel it. If you miss an appointment without canceling, some locations may charge a no-show fee, though this varies.

Troubleshooting common website issues

If the Quest website is slow or won't load, try clearing your browser's cache and cookies, or use a different browser. Sometimes the site experiences heavy traffic during peak hours (early morning and lunch). If you keep having trouble, try again during off-peak hours like mid-afternoon or evening.

If you can't find a location near you or the available times don't work, call 1-866-QUEST-99 to see if a representative can book you at a different location or find an earlier opening. Some labs have walk-in hours that aren't shown online, and a phone representative may be able to tell you about those.

If you've already booked but can't log into your account to view your appointment, use the "Forgot Password" link on the login page to reset it. If you never received your confirmation email, check your spam folder or call the number on your confirmation text message.

Frequently Asked Questions

Do I need a doctor's order to book an appointment on Quest's website?

Not always. Quest offers some tests you can order yourself, like wellness panels or drug screening. Other tests require a doctor's order. The website will tell you during booking whether your test needs one. If you need an order and don't have a doctor, Quest can connect you with one through their site in some states.

Can I book an appointment without insurance?

Yes. Quest will show you the cost of your test upfront if you're uninsured. Prices vary by location and test type. You'll pay at the time of your visit or when you check in. Some Quest locations offer discounts for uninsured patients who pay cash.

What if the website won't let me book because it says I need a doctor's order?

Some tests legally require a doctor's order before a lab can run them. If you need one, you can contact your primary care doctor, an urgent care clinic, or use Quest's doctor referral service on their website. Once you have the order, you can either upload it to the website or bring it to your appointment.

How do I view my test results after my appointment?

Log into your Quest account at www.questdiagnostics.com and click "View Results." Most results are available within 24 to 48 hours. Your doctor will also receive them if they ordered the test. Some results take longer depending on the complexity of the test.

Can I bring someone with me to my appointment?

Yes. A parent, guardian, or support person can come with you. If you're bringing a minor, a parent or guardian must be present. Let the staff know when you arrive if you need someone in the room with you during your blood draw.
