How to Schedule a LabCorp Appointment Online and by Phone

What LabCorp's appointment scheduler does

LabCorp's appointment scheduler lets you book a lab visit for blood work, drug screening, or other tests without calling. You can choose your location, pick a date and time that works for you, and arrive knowing exactly when your appointment starts. The system shows you wait times at different locations so you can pick the one closest to you or the one with the shortest queue.

You do not need to create an account to book through their online scheduler, though having one saves your information for future visits. The scheduler works on desktop and mobile browsers, and LabCorp also has a mobile app that includes the same booking tool.

Key Takeaways

• LabCorp's online scheduler at labcorp.com lets you book same-day or future appointments without calling, and shows real-time wait times at each location.
• You can search by zip code or address to find the nearest patient service center, and the system tells you which tests each location offers.
• Bring your insurance card, photo ID, and any lab order from your doctor — the scheduler does not process these, so you will need them at check-in.
• If you cannot find an available time online, calling 1-800-LAB-CORP (1-800-522-2767) connects you to a scheduler who can book you directly or explain why a location is full.
• Cancellations and changes can be made through the same online scheduler or by phone up to 24 hours before your appointment.

How to book an appointment on LabCorp's website

Go to labcorp.com and look for the "Schedule an Appointment" button on the homepage. Click it and enter your zip code or city to see all patient service centers near you. The scheduler shows each location's address, hours, and current wait time.

Select the location you want to visit. The next screen asks what type of test you need — common options include general wellness panels, drug screening, and pregnancy tests. If you have a specific lab order from your doctor, you can enter the order number or upload a photo of it, though this is not required to book.

Choose your preferred date and time from the available slots. The scheduler shows you only times that are actually open, so you will not book a slot that is full. After you pick a time, enter your name, date of birth, phone number, and email address. You can add insurance information if you have it, but the scheduler will let you complete the booking without it.

Review your appointment details and confirm. You will get a confirmation email with your appointment number, location address, and what to bring. Save this email or take a screenshot — you will need the appointment number at check-in.

Using the LabCorp mobile app

The LabCorp mobile app (available on iOS and Android) has the same appointment scheduler built in. Download the app, tap "Schedule an Appointment," and follow the same steps as the website. The app also stores your past appointments and test results if you create an account, which can be useful if you visit LabCorp regularly.

The app version sometimes loads faster on slower connections and lets you book while you are already out — useful if you decide to get a test done on the same day. You can also receive push notifications about your appointment as a reminder.

What to bring and what happens at check-in

Bring your photo ID, insurance card (if you have one), and any lab order your doctor gave you. The scheduler does not verify insurance or process orders, so staff will do this at check-in. If you do not have an insurance card, you can still be tested — you will just pay out of pocket or work out a payment plan with the location.

Arrive 10 to 15 minutes early so staff can check you in. Tell them your appointment number (from your confirmation email) and they will pull up your booking. If you did not enter your insurance information online, have your card ready. The check-in process usually takes 5 to 10 minutes.

Booking by phone if the online scheduler is full

If the online scheduler shows no available times at your preferred location, call 1-800-LAB-CORP (1-800-522-2767). A scheduler can sometimes find times that do not appear online, or they can explain when the next opening is. Phone lines are usually busiest in the morning, so calling in the afternoon or early evening may be faster.

Have your zip code, preferred dates, and test type ready when you call. The scheduler will book you directly and give you a confirmation number over the phone. Ask them to email or text your confirmation so you have it in writing.

Changing or canceling your appointment

Log into your LabCorp account on the website or app, find your upcoming appointment, and click "Cancel" or "Reschedule." You can make changes up to 24 hours before your appointment time. If you cancel within 24 hours of your appointment, you may be charged a no-show fee depending on your location and insurance.

If you cannot reach the online system, call 1-800-LAB-CORP to cancel or reschedule by phone. Tell them your appointment number and the new time you want. Confirming the change over the phone ensures the location has the update.

Same-day appointments and walk-ins

LabCorp accepts same-day appointments through the online scheduler at many locations. Search for your location and look for times available today — if slots show up, you can book one immediately. Same-day appointments are often available in the afternoon or early evening.

If no same-day times appear online, you can walk into most LabCorp patient service centers without an appointment. Wait times for walk-ins vary by location and time of day. Calling ahead to ask about current wait times helps you decide whether to book online or walk in.

Frequently Asked Questions

Do I need to create a LabCorp account to schedule an appointment?

No. You can book through the online scheduler or app without logging in. Creating an account is optional and mainly useful if you visit LabCorp regularly and want to store your test results and appointment history in one place.

Can I book an appointment if I do not have a lab order from my doctor?

Yes. You can book a test through the scheduler without a doctor's order. LabCorp offers direct-to-consumer tests like wellness panels and drug screens that you can order yourself. At check-in, staff will confirm which test you want and process payment if you do not have insurance.

What if I miss my appointment?

LabCorp may charge a no-show fee, which varies by location. If you cannot make it, cancel through the online scheduler or call 1-800-LAB-CORP as soon as you know. Canceling at least 24 hours ahead usually avoids the fee.

How long does it take to get my test results?

Results timing depends on the test type. Simple tests like drug screens may be ready in 24 hours. More complex panels can take 3 to 5 business days. LabCorp emails you when results are ready, and you can view them through your account on the website or app.

Can I reschedule my appointment to a different location?

Yes. Cancel your current appointment through the scheduler and book a new one at a different location. You can do this online or by calling 1-800-LAB-CORP. Rescheduling to a different location counts as a new appointment, so you will get a new confirmation number.
