How to Cancel a LabCorp Appointment

You can cancel a LabCorp appointment online, by phone, or in person, and the method depends on how you booked it

If you booked your appointment through the LabCorp website or the LabCorp mobile app, you can cancel it directly in the same place without calling. Log into your account, find the appointment in your schedule, and select the cancel option. The system will ask you to confirm, and you'll receive an email confirmation that the cancellation went through.

If you booked by phone or in person at a LabCorp location, you'll need to call LabCorp's appointment line to cancel. The main number is 1-800-LAB-CORP (1-800-522-2677). Have your appointment confirmation number or date of birth ready when you call, and the representative will locate your appointment and process the cancellation immediately.

You can also walk into the LabCorp location where your appointment is scheduled and ask the staff to cancel it at the front desk. This works if you're nearby and want to handle it in person, though calling ahead is faster and avoids a trip if the office is busy.

Key Takeaways

• Online and app bookings can be cancelled directly through your LabCorp account without making a phone call.
• Phone bookings require you to call 1-800-522-2677 with your confirmation number or date of birth to cancel.
• You can cancel in person at any LabCorp location during business hours by speaking to the front desk staff.
• Cancellations are processed immediately, and you'll receive confirmation by email or from the staff member who helped you.
• If you need to reschedule instead of cancelling, you can do that through the same method you used to book.

Cancelling through your LabCorp online account

Log into your account at labcorp.com using your username and password. If you don't have an account, you can create one with your email address. Once you're logged in, look for a section labeled "My Appointments" or "Upcoming Appointments" — this is usually visible on the dashboard or in the main menu.

Find the appointment you want to cancel in the list. Click on it to open the appointment details, which will show the date, time, location, and the type of test you're scheduled for. You should see a "Cancel Appointment" button or link near the top or bottom of the details screen. Click it, confirm that you want to cancel when prompted, and the system will process the cancellation right away.

You'll receive a confirmation email at the address associated with your account within a few minutes. Keep this email for your records. If you don't see the confirmation email, check your spam or junk folder, or log back into your account to verify the cancellation went through.

Cancelling through the LabCorp mobile app

Open the LabCorp mobile app on your phone and sign in with your username and password. The app is available for both iPhone and Android devices and can be downloaded from the App Store or Google Play. Once you're signed in, tap on "Appointments" or a similar menu option to see your upcoming appointments.

Select the appointment you want to cancel from the list. The appointment details screen will show all the information about your visit. Look for a "Cancel" button, which is usually at the bottom of the screen or in a menu (sometimes marked with three dots). Tap it and confirm the cancellation when the app asks you to verify.

The app will show a confirmation message immediately, and you'll also receive an email confirmation. If you want to reschedule instead of cancelling, the app usually offers that option on the same screen — you can pick a new date and time without having to start over.

Cancelling by phone

Call LabCorp's appointment line at 1-800-522-2677. This number is available Monday through Friday, 7 a.m. to 7 p.m. Eastern Time, and Saturday 8 a.m. to 4 p.m. Eastern Time. Wait times vary depending on how busy the line is, but you typically reach someone within a few minutes during business hours.

When a representative answers, tell them you want to cancel an appointment. Have your confirmation number ready — you can find this in your confirmation email or in your online account. If you don't have the confirmation number, the representative can look up your appointment using your date of birth and the location where you're scheduled. Provide the date and time of your appointment to help them find it faster.

The representative will confirm the cancellation with you and may ask why you're cancelling (this is optional information). Once the cancellation is confirmed, ask for a confirmation number for your records. You'll receive an email confirmation within a few minutes, but having the number from the call is helpful if you need to reference the cancellation later.

Cancelling in person at a LabCorp location

Walk into the LabCorp location where your appointment is scheduled during their business hours. Most locations are open Monday through Friday from 7 a.m. to 6 p.m., and Saturday from 8 a.m. to 4 p.m., though hours vary by location. You can find the hours for your specific location on the LabCorp website by entering your zip code.

Go to the front desk and tell the staff member that you want to cancel your appointment. Provide your name and date of birth, or your confirmation number if you have it. The staff member will look up your appointment in the system and process the cancellation right away. They'll give you a verbal confirmation and may print a receipt showing the cancellation.

This method is useful if you're already at the location or nearby, but calling ahead is faster and means you don't have to wait if the office is busy. If you're cancelling because you can't make the appointment time, ask the staff member if they can reschedule you for a different time while you're there — this saves you a phone call later.

What happens after you cancel

Once your cancellation is processed, your appointment slot becomes available for other people to book. You won't be charged for the cancelled appointment. If you had any paperwork or forms prepared for the visit, you can keep them for your records or discard them — you won't need to submit them if you're not going.

If you cancelled because you need to reschedule, you can book a new appointment right away using any of the same methods (online, app, or phone). There's no penalty for cancelling and rebooking, and you can do this as many times as you need. If you're cancelling because you no longer need the test, make sure you've discussed this with your doctor first, since they may have ordered the test for a specific reason.

Keep your cancellation confirmation for your records. If you receive a reminder call or email about an appointment you've already cancelled, it usually means the cancellation didn't process correctly. In that case, call the appointment line again to confirm the cancellation or ask them to remove the reminder.

Frequently Asked Questions

Can I cancel my appointment less than 24 hours before it's scheduled?

Yes, you can cancel at any time, even a few hours before your appointment. However, LabCorp may not be able to fill your slot if you cancel very close to your appointment time. If you're going to be late instead of cancelling, call ahead to let them know — they may be able to hold your spot or fit you in later that day.

Will I get in trouble for cancelling my appointment?

No. Cancelling a LabCorp appointment has no penalty or consequence. You won't be charged, and it won't affect your ability to book future appointments. LabCorp understands that schedules change and appointments need to be cancelled sometimes.

What if I can't find my confirmation number?

You don't need your confirmation number to cancel. When you call or visit in person, the staff can look up your appointment using your name, date of birth, and the location where you're scheduled. If you're cancelling online, you just need to log into your account to see your appointments.

Can I cancel someone else's appointment for them?

If you're cancelling online or through the app, you need to log into that person's account, which requires their username and password. If you're calling or visiting in person, LabCorp may ask for the person's date of birth or other identifying information to confirm you're authorized to cancel on their behalf, depending on their privacy policies.

What if I want to reschedule instead of cancelling?

You can reschedule directly through your online account or the app by selecting your appointment and choosing "Reschedule" instead of "Cancel." By phone, tell the representative you want to reschedule, and they can book you for a new date and time in the same call. In person, the staff can reschedule you at the front desk.
