How to Schedule and Manage Your LabCorp Appointment Online
LabCorp's online appointment system lets you book lab work directly through their website or mobile app without calling
LabCorp operates Labcorp.com as the main hub for scheduling. You can visit the site, search for a nearby lab location, pick a date and time that works for you, and confirm your appointment in minutes. The same booking system is available through the LabCorp mobile app, which you can download on iOS or Android. Both routes show you real-time availability and send you confirmation details by email or text.
The online system works best when you already know what test your doctor ordered. If you're unsure, you can call LabCorp's customer service at 1-800-LAB-CORP (1-800-522-2677) to confirm the test code before you book, or you can bring your doctor's order to the lab and staff will verify it when you arrive.
Key Takeaways
- Book your LabCorp appointment at Labcorp.com or through the LabCorp mobile app by entering your zip code, selecting a location, and choosing an available time slot.
- You will need your date of birth, insurance information (if you have it), and your doctor's test order or the test code to complete your booking.
- Confirmation arrives by email or text within minutes, and you can reschedule or cancel through the same website or app up until your appointment time.
- Walk-ins are accepted at most LabCorp locations, but booking online typically means a shorter wait and guarantees your spot.
- If your doctor's order is not yet in the LabCorp system, you can bring a paper copy to your appointment or ask your doctor's office to send it electronically.
What you need before you book online
Have your date of birth and a valid form of identification ready. LabCorp will ask for this information during booking and you'll need to bring the ID to your appointment. If you have insurance, have your insurance card handy — the website will ask for your member ID and group number, though you can skip this and pay out-of-pocket if you prefer.
You also need to know what test your doctor ordered. This might be listed on a paper order your doctor gave you, or your doctor's office may have sent it electronically to LabCorp already. If you don't have the test name or code, call your doctor's office and ask them to provide it, or call LabCorp at 1-800-522-2677 and give them your name and date of birth so they can look up your pending orders.
Step-by-step: booking through Labcorp.com
Go to Labcorp.com and click "Schedule an Appointment" or "Book Now" (the button location may vary). Enter your zip code or city name to find nearby locations. The site will show you a list of labs with their addresses, hours, and how many appointments are open that day.
Select the location closest to you. The calendar will show available dates — usually the next 7 to 14 days, depending on how busy that lab is. Click the date you want, then choose a time slot. Most labs offer morning and afternoon windows. After you select your time, you'll enter your personal information: full name, date of birth, phone number, and email address.
Next, the site asks whether you have insurance and what type (commercial, Medicare, Medicaid, or uninsured). If you have insurance, enter your member ID and group number from your card. Then select your test from a dropdown menu or search box — the site will show you tests your doctor has already ordered for you, or you can search by test name. Review your information, confirm the appointment, and you're done. You'll receive a confirmation email and text message with your appointment details and any instructions you need to follow before your visit.
Using the LabCorp mobile app
The LabCorp app follows the same process as the website. Download it from the Apple App Store or Google Play, create an account with your email and a password, and log in. Tap "Schedule an Appointment," enter your zip code, and proceed through location selection, date and time, and personal information the same way you would on the website.
The app also lets you view past appointments, access your test results once they're ready, and manage your insurance information in one place. If you book through the app, you can check in for your appointment using the app as well — some locations let you check in remotely a few minutes before your scheduled time, which can reduce wait time when you arrive.
What happens if your doctor's order isn't in the system yet
If you try to book and don't see your test listed, your doctor's order may not have reached LabCorp yet. This can happen if your doctor ordered the test very recently or if they use a different lab system. You have two options: wait a few hours or until the next business day and try booking again, or bring a paper copy of your doctor's order to the lab when you arrive.
You can also call your doctor's office and ask them to send the order to LabCorp directly. Most offices can do this electronically within a few minutes. If you're in a hurry, you can walk into any LabCorp location without an appointment — they accept walk-ins at all locations — and staff will check whether your order is in their system. If it is, they'll process you immediately. If it isn't, they'll ask you to provide a copy of your order or have your doctor send it.
Rescheduling or canceling your appointment
Log back into Labcorp.com or the app, go to "My Appointments," and find the appointment you want to change. Click "Reschedule" to pick a new date and time at the same location, or "Cancel" to remove it entirely. You can make these changes anytime up until your appointment time — there's no penalty for canceling or rescheduling.
If you need to cancel or reschedule after hours, you can still do it through the website or app. The change will take effect immediately. If you have questions about your appointment or need to speak to someone, call 1-800-522-2677 during business hours and a representative can help you.
What to bring and what to expect on the day
Bring your confirmation email or text message (or show it on your phone), your photo ID, and your insurance card if you have one. Some tests require you to fast (not eat or drink anything except water) for a certain number of hours beforehand — your confirmation email will tell you if fasting is required for your specific test. If fasting is needed and you forget, tell the lab staff when you check in; they may be able to reschedule you for another time.
Arrive 5 to 10 minutes early to allow time for check-in. You'll give your name and date of birth at the front desk, and staff will verify your test order and insurance information. Then you'll wait for a phlebotomist (the person who draws blood) or technician to call you back. The actual test usually takes 5 to 15 minutes depending on what's being done. After your appointment, you can leave immediately — results typically arrive within 24 to 48 hours and you'll receive an email notification when they're ready.
Frequently Asked Questions
Can I book an appointment if I don't have insurance?
Yes. During booking, select "Uninsured" when asked about insurance coverage. LabCorp will show you the out-of-pocket cost for your test before you confirm your appointment. Prices vary by test and location, but you can pay at the lab when you arrive or sometimes online during booking.
What if I don't know my test code or what test my doctor ordered?
Call your doctor's office and ask them to tell you the test name or code. You can also call LabCorp at 1-800-522-2677 with your name and date of birth, and they can look up any pending orders your doctor has sent them. If nothing is in the system yet, ask your doctor to send the order to LabCorp electronically.
Can I check in early or late for my appointment?
Most LabCorp locations allow you to check in up to 15 minutes before your scheduled time. If you're running late, call the lab directly or use the app to reschedule to a later time slot. Arriving significantly late may mean a longer wait or the lab may ask you to reschedule.
How do I see my test results after my appointment?
Results appear in your LabCorp account on Labcorp.com or the app, usually within 24 to 48 hours. You'll receive an email notification when they're ready. Your doctor's office will also receive the results electronically if they ordered the test through their system.
What if I need to cancel my appointment the day of?
You can cancel through the website or app anytime, even on the day of your appointment. If you need to speak to someone immediately, call the lab location directly — their phone number is in your confirmation email — or call 1-800-522-2677.
