How to Check Your LabCorp Appointment
Check your appointment through the LabCorp patient portal or by phone
The fastest way to check your LabCorp appointment is to log into LabCorp OnDemand, the patient portal where you can see your scheduled test date, time, and location. If you don't have a portal account, you can create one at labcorp.com using your email address. Once logged in, your upcoming appointments appear in the dashboard — you'll see the test name, the lab address, and any preparation instructions specific to that test.
If you prefer not to use the online portal, you can call LabCorp's appointment line at 1-800-LAB-CORP (1-800-522-2677) and speak with a representative who can pull up your appointment by your name and date of birth. This route takes longer but requires no password or login.
A third option is to check any confirmation email or text message you received when you booked the appointment. Many people receive an automated confirmation that includes the appointment details and a link to reschedule or cancel if needed.
Key Takeaways
- Log into LabCorp OnDemand at labcorp.com to see your appointment date, time, location, and test-specific instructions in one place.
- Call 1-800-LAB-CORP (1-800-522-2677) if you don't have a portal account or prefer to speak with someone directly.
- Check your confirmation email or text message for appointment details and a link to make changes.
- Write down your appointment details or set a phone reminder a few days before so you don't miss it.
What information you'll see in the portal
When you log into LabCorp OnDemand, the appointment section shows the name of the test you're having (for example, "Lipid Panel" or "Complete Blood Count"), the date and time, and the full address of the LabCorp location where you'll go. You'll also see any fasting requirements or other preparation steps — for instance, whether you need to avoid food or drink before the test, or whether you should wear loose clothing for easier blood draw access.
The portal also displays your test requisition, which is the order your doctor sent to LabCorp. This document lists what tests are being run and any special instructions from your doctor. Having this information in advance means you can prepare properly and answer any questions the phlebotomist asks when you arrive.
How to create a LabCorp OnDemand account if you don't have one
Go to labcorp.com and look for the "Sign In" or "Patient Portal" link, usually at the top right of the page. Click "Create Account" and enter your email address, a password, and your date of birth. LabCorp will send a verification email to confirm your address — click the link in that email to activate your account.
Once your account is active, you can log in anytime to check appointments, view past test results, and update your contact information. If you have trouble creating an account or don't receive the verification email, call 1-800-LAB-CORP and a representative can help you set it up over the phone or troubleshoot the issue.
What to do if you can't find your appointment in the portal
If you log in and don't see an upcoming appointment, the most common reason is that your doctor's office hasn't sent the test order to LabCorp yet, or it was sent to a different lab. Contact your doctor's office to confirm they ordered the test and that it's going to LabCorp, not another lab network.
Another possibility is that the appointment was scheduled under a different name or email address — for example, if someone else in your household booked it on your behalf. Try logging in with a different email if you have one, or call 1-800-LAB-CORP to search by your name and date of birth instead.
If you scheduled your appointment through a third-party service like an employer wellness program or an urgent care clinic, that appointment may not appear in the LabCorp portal. In that case, check your confirmation email from the service that booked it, or contact that organization directly for your appointment details.
How to reschedule or cancel from the portal
Most appointments can be rescheduled or canceled directly from LabCorp OnDemand. Log in, find the appointment, and look for a "Reschedule" or "Cancel" button. Click it, select a new date and time if you're rescheduling, and confirm. You'll receive a new confirmation email with the updated details.
If the reschedule button isn't available — which sometimes happens close to your appointment date — call 1-800-LAB-CORP to make the change. Some appointments booked through your doctor's office or an employer program may need to be rescheduled through that organization instead of directly through LabCorp.
What to bring and how to prepare on appointment day
Bring a photo ID and your insurance card to your appointment. If you don't have insurance, bring your ID anyway — LabCorp can still process your test. Check the portal the day before to review any fasting or preparation instructions; for example, some blood tests require you to fast for 8 to 12 hours beforehand, while others have no restrictions.
Arrive 10 to 15 minutes early so you have time to check in. The phlebotomist will verify your name and date of birth, confirm which tests you're having, and answer any last-minute questions. The actual blood draw or sample collection usually takes just a few minutes.
Frequently Asked Questions
Can I check my appointment on my phone?
Yes. LabCorp OnDemand works on phones and tablets — you can log in through the website or download the LabCorp mobile app from the Apple App Store or Google Play Store. The app shows the same appointment information as the website.
What if I don't remember my portal password?
On the LabCorp OnDemand login page, click "Forgot Password" and enter your email address. LabCorp will send a password reset link to your email. Click the link, create a new password, and log in. If you don't receive the email, check your spam folder or call 1-800-LAB-CORP for help.
How far in advance can I see my appointment in the portal?
Appointments usually appear in the portal within 24 hours of being scheduled by your doctor's office. If your doctor just ordered the test today, it may not show up until tomorrow. If it's been more than a day and you still don't see it, contact your doctor's office to confirm the order was sent.
Can I check someone else's appointment if I have their permission?
No. Each LabCorp OnDemand account is personal and password-protected. If you need to check an appointment for a family member or dependent, they need to log in themselves, or you can call 1-800-LAB-CORP with their name and date of birth and ask a representative to confirm the details for you.
What if my appointment time changed and I didn't get a notification?
Log into the portal to see the current appointment time — sometimes changes are made on the LabCorp side without a new email being sent. If you believe the time is wrong, call 1-800-LAB-CORP to confirm. If you need to change it yourself, use the reschedule button in the portal or call to request a different time.
