How to Schedule a LabCorp Appointment Online or by Phone

You can book a LabCorp appointment through their website, by phone, or by walking in without an appointment

LabCorp lets you schedule lab work in three ways: online through their website or mobile app (usually the fastest), by calling their appointment line, or by arriving at a location during walk-in hours. Most people book online because you can see available times immediately and choose the slot that fits your schedule. You'll need to know which test your doctor ordered, your insurance information, and a valid ID when you arrive.

The appointment itself is brief — typically 5 to 15 minutes depending on what tests you're having done. You don't need to do anything special to prepare unless your doctor told you to fast or avoid certain foods before the visit. LabCorp has thousands of patient service centers across the United States, so you can usually find one near your home or workplace.

Key Takeaways

• Book online at labcorp.com or through the LabCorp mobile app to see available appointment times and confirm your slot instantly.
• Call 1-800-LAB-CORP (1-800-522-2677) to schedule by phone if you prefer speaking with someone or need help finding a nearby location.
• Bring your insurance card, photo ID, and any paperwork your doctor gave you about the test being ordered.
• Walk-in appointments are available at most LabCorp locations during regular business hours, though wait times vary by location and time of day.
• If your doctor ordered the test, LabCorp can usually access the order electronically, so you don't need to bring a printed copy.

Scheduling online through LabCorp's website or app

Go to labcorp.com and click "Schedule a Test" or open the LabCorp mobile app (available on iOS and Android). Enter your zip code or city to find nearby patient service centers. The website will show you available appointment times for the next several days, usually in 15-minute or 30-minute slots depending on the location.

You'll be asked to enter basic information: your name, date of birth, phone number, and email address. The system will ask whether you have an order from your doctor already. If your doctor sent the order to LabCorp electronically (which most do), the system can pull it up using your name and date of birth. If not, you can upload an image of the order or enter the test name manually.

Next, enter your insurance information. LabCorp will verify your coverage and tell you whether there's a copay or if the test is covered at no cost to you. You can then select your appointment time and confirm. You'll receive a confirmation email with your appointment details, location address, and parking information if available.

Calling LabCorp to book by phone

Call 1-800-LAB-CORP (1-800-522-2677) to speak with someone who can schedule your appointment. This line is open Monday through Friday, 8 a.m. to 8 p.m. Eastern time, and Saturday 9 a.m. to 5 p.m. Eastern time. Have your insurance card and doctor's order ready when you call, though the representative can often look up your order if you provide your name and date of birth.

The representative will ask which location is most convenient for you and show you available times. They can answer questions about what to bring, whether you need to fast, or what the test involves. After you book, they'll give you a confirmation number and send details to your email or phone.

What to bring to your LabCorp appointment

Bring a valid photo ID (driver's license, passport, or state ID) and your current insurance card. If you have a printed copy of your doctor's order, bring that too, though LabCorp can usually find it in their system. If you're paying out of pocket, ask about the cost when you schedule — LabCorp publishes prices online for many common tests.

Wear loose, comfortable clothing with sleeves that roll up easily if you're having blood drawn. If your doctor told you to fast before the test (usually for fasting glucose or lipid panel tests), follow those instructions — don't eat or drink anything except water after midnight the night before, unless your doctor said otherwise.

Arrive 10 to 15 minutes early so you have time to check in. Bring a list of any medications you're taking if this is your first visit to that location, though the staff will ask about them during check-in anyway.

Walk-in appointments and same-day testing

Most LabCorp patient service centers accept walk-ins during their regular hours without an appointment. Walk-in wait times vary — some locations have short waits during off-peak hours (mid-morning or mid-afternoon on weekdays), while others may have 30-minute to 1-hour waits during lunch or after work. You can call ahead to ask about current wait times at your nearest location.

If you walk in, bring the same documents you would for a scheduled appointment: photo ID, insurance card, and your doctor's order if you have it. The check-in process is the same whether you scheduled ahead or walked in. If LabCorp can't find your doctor's order in their system, you may be asked to contact your doctor's office to have it sent, or you can pay out of pocket if you prefer not to wait.

Understanding your appointment confirmation and what happens next

After you schedule, you'll receive a confirmation with your appointment date, time, location address, and a confirmation number. Save this confirmation or take a screenshot — you'll need the confirmation number if you need to reschedule or cancel. Most confirmations also include parking details and directions to the patient service center.

LabCorp typically processes results within 24 to 48 hours, though some tests take longer. You can view your results online through your LabCorp patient portal (you can create an account at labcorp.com) or through your doctor's patient portal if your doctor has access. Your doctor will review the results and contact you if anything needs follow-up.

Rescheduling or canceling your appointment

If you need to change your appointment time, log into your LabCorp account online, find your scheduled appointment, and select "Reschedule." The system will show you other available times at the same location or nearby locations. You can also call 1-800-LAB-CORP to reschedule by phone.

If you need to cancel, do so at least a few hours before your appointment time if possible. Canceling online takes a few seconds; canceling by phone takes a quick call. There's no penalty for canceling, and you can reschedule whenever you're ready.

Frequently Asked Questions

Do I need my doctor's order to schedule a LabCorp appointment?

You need an order from your doctor to have the test done, but you don't need to have it in hand to schedule. LabCorp can look up most orders electronically using your name and date of birth. If your doctor hasn't sent the order yet, you can schedule and provide it later, or call your doctor's office to have them send it before your appointment.

What if LabCorp can't find my doctor's order when I arrive?

Contact your doctor's office and ask them to send the order to LabCorp right away. You can wait at the location while they do this, or reschedule for another time. Some people choose to pay out of pocket for the test rather than wait, though this is usually more expensive than going through insurance.

How much does a LabCorp appointment cost?

Cost depends on your insurance and the specific test. LabCorp's website shows cash prices for many common tests if you're uninsured or paying out of pocket. If you have insurance, your copay or coinsurance will show when you schedule online. Call 1-800-LAB-CORP if you want to know the cost before scheduling.

Can I schedule a LabCorp appointment for someone else?

You can schedule for a family member or dependent if you have their information, but they'll need to bring their own photo ID to the appointment. If you're scheduling for a minor, you'll need to be their parent or legal guardian.

What time of day should I schedule my appointment?

Early morning appointments (7 a.m. to 9 a.m.) often have shorter wait times and are best if you're fasting. Mid-morning and mid-afternoon slots are usually less busy than lunch time or right after work. If you have a choice, pick whatever time works best for your schedule — LabCorp can handle appointments throughout the day.
