How to Schedule a Labcorp Appointment Online or by Phone

You can schedule a Labcorp appointment through their website, by phone, or at a walk-in location

Labcorp operates thousands of patient service centers across the United States. You can book an appointment in advance through their online scheduling system, call their appointment line, or walk in without scheduling at most locations. The fastest route is usually their website, which shows available times at your nearest center and lets you confirm a slot in minutes.

What you need before you schedule depends on whether your doctor ordered the test or you are paying out of pocket. If you have a doctor's order, have that information ready. If you are scheduling a test you are paying for yourself — like a wellness panel or drug screening — you can proceed without a prior order at most Labcorp locations.

Key Takeaways

• Most Labcorp patient service centers accept walk-ins during their posted hours, though wait times may be longer than scheduled appointments.
• Bring a photo ID and insurance card to your appointment; if you have a doctor's order, bring that as well or have the order number ready.
• Labcorp locations vary in which tests they offer, so confirm your specific test is available at your chosen center before you schedule.

Scheduling through Labcorp's website

Go to labcorp.com and select "Schedule an Appointment" or "Find a Location" from the homepage. Enter your zip code or city to see all patient service centers near you, along with their hours and which tests each location offers. The website shows you available appointment slots for the next several days, usually starting with same-day options if the center has openings.

Click on a time slot that works for you. You will be asked to enter your name, date of birth, phone number, and email address. If you have a doctor's order, you can enter the order number or provider name so Labcorp can pull up the test details. If you do not have an order, you can select from Labcorp's list of tests available for self-pay. After you confirm your information, you will receive an appointment confirmation by email and text message.

The website also lets you check in online before your appointment, which can speed up the process at the center. You can do this up to 24 hours before your scheduled time.

Scheduling by phone

Call Labcorp's appointment line at 1-800-LAB-CORP (1-800-522-2676). A representative will ask for your zip code or preferred location, the date and time you want to come in, and whether you have a doctor's order. If you have an order, provide the order number or your provider's name. If you do not, tell the representative which test you need, and they will confirm whether it is available at your chosen location.

The representative will book your appointment and give you a confirmation number. Ask them to email or text your confirmation so you have it in writing. Phone wait times are typically shorter early in the morning or mid-afternoon on weekdays, and longer during lunch hours and late afternoon.

Walking in without an appointment

Most Labcorp patient service centers accept walk-ins during their posted hours. You do not need to call ahead or schedule online. Bring your photo ID, insurance card if you have one, and your doctor's order if one exists. Check the Labcorp website or call ahead to confirm the center's hours and whether they are currently accepting walk-ins, as some locations may temporarily close or limit walk-in capacity.

Walk-in wait times vary widely depending on the time of day and how busy the center is. Mornings and early afternoons tend to be less crowded than late afternoon. If you need results quickly or prefer not to wait, scheduling an appointment in advance is usually faster.

What to bring to your appointment

Bring a valid photo ID — a driver's license, passport, or state ID card. Bring your insurance card if you have insurance. If your doctor ordered the test, bring the paper order or have the order number ready; Labcorp can also look it up by your provider's name and your date of birth. If you are paying out of pocket, you do not need an order, but confirm the cost before your appointment if you want to know what to expect.

If you are fasting for your test — which some blood tests require — do not eat or drink anything except water for the time period your doctor or the test instructions specify. Labcorp's website and confirmation email will tell you if fasting is required for your specific test.

Rescheduling or canceling an appointment

If you need to change your appointment time, log into your Labcorp account on their website and select "Manage Appointments," or call 1-800-LAB-CORP. You can reschedule to a different time at the same location or switch to a different center. If you cancel, do so at least a few hours before your appointment time so the slot can be offered to another person.

If you miss an appointment without canceling, some Labcorp locations may charge a no-show fee. Check your confirmation email for the center's no-show policy.

Finding a Labcorp location that offers your test

Not every Labcorp patient service center offers every test. Some tests require specialized equipment or are only available at certain larger locations. When you search for an appointment on the website, the system automatically shows you only centers that offer the test you need. If you are calling, the representative will confirm whether your chosen location has the test available.

If your nearest center does not offer the test, the website and phone line will show you the closest alternative location. Some tests may also be available through Labcorp's home collection service, where a phlebotomist comes to your home — ask about this option if traveling to a center is difficult.

Frequently Asked Questions

Can I schedule a Labcorp appointment same-day?

Yes, most Labcorp locations have same-day appointment slots available, especially in the morning and early afternoon. Check the website to see what times are open at your nearest center, or call 1-800-LAB-CORP to ask about same-day availability. Walk-ins are also accepted at most locations without advance notice.

Do I need a doctor's order to schedule a test at Labcorp?

No. Labcorp offers many tests for self-pay without a doctor's order, including wellness panels, drug screenings, and individual lab tests. If your doctor ordered a specific test, you can provide the order number when you schedule. If you do not have an order, you can choose from Labcorp's self-pay menu.

What if I do not know my doctor's order number?

Provide your doctor's name and your date of birth when you schedule, and Labcorp can look up the order in their system. If the order is not found, contact your doctor's office to get the order number or have them send it to Labcorp directly.

Can I reschedule my appointment online?

Yes, if you have a Labcorp account, log in and select "Manage Appointments" to reschedule or cancel. You can also call 1-800-LAB-CORP to make changes by phone. Reschedule as soon as you know you cannot make your appointment so the slot can be offered to someone else.

How long does a typical Labcorp appointment take?

A scheduled appointment usually takes 15 to 30 minutes from check-in to completion, depending on which tests you are having done. Walk-in wait times can be longer and vary by location and time of day. Arrive a few minutes early to allow time for check-in.
