How to Find and Schedule a LabCorp Appointment Near You

The fastest way to find a LabCorp location near you

LabCorp's website has a location finder that shows you every lab within your area, their hours, and whether you need an appointment or can walk in. Go to labcorp.com, click "Find a Lab," enter your zip code or city, and you'll see a map with addresses, phone numbers, and directions. Most locations accept both scheduled appointments and walk-ins, though appointment slots often fill faster during morning hours.

You can also call LabCorp's main line at 1-800-LAB-CORP (1-800-522-2677) and a representative will tell you which locations are nearest and help you schedule over the phone. This is useful if you're not sure which tests you need or if you want to confirm that a specific location has availability on your preferred day.

If you're a patient at a specific doctor's office or hospital system, ask your provider's staff to schedule the lab work for you. They often have standing relationships with LabCorp locations and can book you directly, sometimes with paperwork already sent ahead.

Key Takeaways

• LabCorp's location finder at labcorp.com shows hours, directions, and whether walk-ins are accepted at each lab near you.
• Most LabCorp locations operate Monday through Friday with limited Saturday hours, and morning appointments typically have shorter wait times.
• You can schedule online, by phone at 1-800-522-2677, or through your doctor's office, and you'll need your insurance card and a valid ID at your appointment.
• Walk-in appointments are available at most locations but may mean a longer wait than a scheduled time slot.
• Bring any paperwork your doctor gave you, including the lab requisition form, to your appointment.

What information you need before you schedule

Before you book, have your insurance card and a photo ID ready. LabCorp will ask for your date of birth, insurance information, and the reason for the lab work. If your doctor ordered specific tests, you'll need the lab requisition form — this is usually a printed sheet or an electronic order that your doctor's office sends to LabCorp ahead of time.

If you don't have a requisition form, you can still go to LabCorp, but you'll need to know what tests your doctor wants run. Call your doctor's office and ask them to either give you the form or send it directly to the LabCorp location you plan to visit. This speeds up your check-in on the day of your appointment.

Scheduling online versus by phone

Scheduling online through labcorp.com is usually the quickest option. You enter your zip code, pick a location, choose a date and time from available slots, and confirm your insurance and contact information. You'll get a confirmation email with your appointment details and a barcode you can show when you arrive.

Calling 1-800-522-2677 takes longer but lets you ask questions about fasting requirements, what to bring, or whether your insurance is accepted at a specific location. Representatives can also help if you're unsure which tests you need or if you want to reschedule an existing appointment. Phone lines are typically busiest in the morning and early afternoon.

Walk-in appointments and wait times

Most LabCorp locations accept walk-ins without an appointment, though you may wait 15 minutes to an hour depending on how busy the lab is. Walk-in wait times are usually shortest first thing in the morning, around 7 or 8 a.m., and longest between 11 a.m. and 2 p.m. If you're in a hurry or prefer not to wait, scheduling ahead is the better choice.

When you walk in, bring your insurance card, photo ID, and any lab requisition form your doctor gave you. The staff will check you in at the front desk and let you know the estimated wait time. If the wait is longer than you're willing to spend, you can ask to schedule an appointment for another day instead.

Hours and location types near you

Most LabCorp patient service centers are open Monday through Friday from 7 a.m. to 6 p.m., with some locations opening as early as 6 a.m. Saturday hours vary — some labs are open 8 a.m. to 1 p.m. on Saturday, while others are closed. Very few locations have Sunday hours. When you search for a location, the website shows the exact hours for each lab.

LabCorp also operates inside some hospitals, urgent care centers, and retail pharmacies like Walgreens and CVS. These locations may have different hours than standalone LabCorp labs. If you're looking for evening or weekend availability, searching by location type can help you find a pharmacy or urgent care location with extended hours.

What to bring and how to prepare

Bring your insurance card, a photo ID, and your lab requisition form if you have one. Wear loose, comfortable clothing with sleeves that roll up easily — this makes it simpler for the phlebotomist to access your arm. If your doctor told you to fast before your appointment (no food or drink except water for a certain number of hours), follow those instructions exactly, as some blood tests require fasting to be accurate.

Arrive 10 to 15 minutes early if you have a scheduled appointment so you can complete any paperwork at check-in. If you're a new patient at that location, you may be asked to fill out a health history form. Bring a pen and be ready to provide your emergency contact information and current medications.

After your appointment: getting your results

LabCorp usually processes results within one to three business days, though some tests take longer. You can view your results online through LabCorp's patient portal if you create an account during check-in, or you can call the location where you had your test done. Your doctor's office will also receive a copy of your results and may contact you if anything needs follow-up.

If you don't hear from your doctor within a week, call their office to ask about your results. Don't assume no news is good news — sometimes results get delayed or filed without a call to the patient. Your doctor can explain what the numbers mean and whether any next steps are needed.

Frequently Asked Questions

Do I need an appointment or can I just walk in?

Most LabCorp locations accept both walk-ins and scheduled appointments. Walk-ins may have a longer wait, especially during mid-day hours. Scheduling ahead guarantees a specific time slot and usually means a shorter visit overall.

What if my insurance isn't accepted at the location I want?

Call LabCorp at 1-800-522-2677 or check the location details on their website before you schedule. If your insurance isn't accepted there, the location finder will show you other nearby labs that do accept it. You can also ask your doctor's office which LabCorp locations are in-network for your plan.

Can I reschedule or cancel my appointment?

Yes. If you scheduled online, log into your account and change your appointment. If you scheduled by phone or through your doctor's office, call the location directly or call 1-800-522-2677. Try to reschedule at least 24 hours before your appointment time.

What if I don't have a lab requisition from my doctor?

Contact your doctor's office and ask them to send the order to LabCorp or give you a copy. You can still go to LabCorp without one, but you'll need to know exactly which tests your doctor wants, and check-in will take longer. Some LabCorp locations also offer wellness screening tests you can order directly without a doctor's order.

How long does a typical appointment take?

A scheduled appointment usually takes 15 to 30 minutes from check-in to leaving, depending on how many tests you need. Walk-ins may take longer if there's a wait. The actual blood draw itself takes only a few minutes.
