How to Schedule and Manage Your Labcorp Appointment Online

You can schedule a Labcorp appointment through their website, by phone, or in person at a patient service center

Labcorp operates thousands of patient service centers across the United States where you can have blood work and other lab tests done. To schedule an appointment, you have three main routes: use the Labcorp.com appointment scheduler, call their scheduling line, or walk into a center during hours they accept walk-ins. The online scheduler is the fastest option if you know which test your doctor ordered and which location works for you.

Before you schedule, have your doctor's order or test requisition ready. Labcorp will not perform tests without a valid order from a healthcare provider. If you do not have an order yet, you will need to contact your doctor's office first — Labcorp cannot order tests on your behalf.

The appointment itself typically takes 15 to 30 minutes from check-in to completion, though wait times vary by location and time of day. Most centers are open early morning through evening on weekdays, with limited weekend hours at some locations.

Key Takeaways

• You must have a doctor's order or test requisition before scheduling; Labcorp cannot order tests without one from a healthcare provider.
• The Labcorp.com scheduler lets you pick your test type, location, and preferred date and time in one process.
• You can also call Labcorp's scheduling line or walk into a patient service center during business hours without an appointment.
• Bring a photo ID and insurance card to your appointment, along with any paperwork your doctor gave you.
• If you need to reschedule or cancel, you can do so through the same website or by calling the scheduling line.

How to schedule through Labcorp.com

Go to Labcorp.com and look for the "Schedule an Appointment" or "Find a Lab" button on the homepage. The site will ask you to enter your zip code or city to see nearby patient service centers. You will then select which location works best for you based on address and hours.

Next, you will choose your test type from a list. The site shows common tests like lipid panels, glucose screening, and drug screening, but you can also search by test name if you know what your doctor ordered. Once you select the test, the scheduler shows available appointment slots at that location. Pick the date and time that works for you.

You will then enter your personal information: name, date of birth, phone number, and email address. The site will ask whether you have insurance and which plan, or whether you are paying out of pocket. You will receive a confirmation email with your appointment details, a check-in link, and instructions on what to bring.

Some tests require fasting (not eating or drinking anything but water for 8 to 12 hours before the appointment). The scheduler will tell you if fasting is required for your specific test. If it is, plan your appointment for early morning so the fasting window is easier to manage.

Scheduling by phone or walk-in

If you prefer not to use the website, call Labcorp's scheduling line at 1-800-LAB-CORP (1-800-522-2676). A representative will ask for your zip code, the test your doctor ordered, and your preferred date and time. They will confirm your insurance information and give you an appointment confirmation number. This route takes about 10 minutes.

Many Labcorp patient service centers also accept walk-ins during their regular hours. You do not need an appointment — just bring your doctor's order, photo ID, and insurance card. Walk-in wait times depend on how busy the center is at that moment. Calling ahead or scheduling online lets you skip the wait.

What to bring to your appointment

Bring a government-issued photo ID (driver's license, passport, or state ID card). Bring your insurance card if you have one. If your doctor gave you any paperwork with your test order, bring that too.

Wear loose, comfortable clothing with sleeves that roll up easily if you are having blood drawn. This makes it faster and easier for the phlebotomist to access your arm. If you are fasting for your test, do not eat or drink anything except water from the time your fasting window begins until after your blood is drawn.

If you are a new patient at that location, arrive 10 to 15 minutes early to complete check-in paperwork. If you have been to that center before, you can arrive right at your appointment time.

Rescheduling or canceling your appointment

If you need to change your appointment, log into Labcorp.com with the email address you used to schedule. Find your upcoming appointment in your account and select the option to reschedule. You will see available times at the same location or can choose a different center. Confirm your new appointment time.

You can also call the scheduling line at 1-800-522-2676 to reschedule by phone. Have your confirmation number ready. If you need to cancel instead of reschedule, you can do that through the website or by phone as well.

If you cannot make your appointment, cancel or reschedule as soon as you know. This frees up the slot for someone else and prevents no-shows on your record.

What happens after your appointment

After your test is complete, Labcorp sends your results to your doctor's office. Your doctor will review them and contact you with the results and any next steps. You can also view many results yourself through Labcorp's online patient portal if you create an account on their website.

Results typically appear in the portal within 24 to 48 hours for routine tests, though some specialized tests take longer. Your doctor's office may contact you before the results are fully available if they need to discuss urgent findings.

Frequently Asked Questions

Can I schedule an appointment without a doctor's order?

No. Labcorp requires a valid order from a licensed healthcare provider before performing any test. If you do not have an order, contact your doctor's office and ask them to send one to Labcorp. Some employers and insurance plans offer wellness screenings that include standing orders, which you can ask your doctor about.

What if I do not know which test my doctor ordered?

Call your doctor's office and ask them to tell you the test name or code. You can also ask them to email or fax the order directly to Labcorp so you have it in writing. When you schedule, you can search by test name or ask the Labcorp scheduler to help you find it.

Do I have to fast before my appointment?

Only if your specific test requires it. The Labcorp scheduler will tell you during the booking process whether fasting is required. Common tests that require fasting include glucose and lipid panels. If fasting is required, the scheduler will recommend scheduling early morning so the fasting window is shorter.

Can I see my test results online?

Yes, if you create a patient account on Labcorp.com. You can view most routine results within 24 to 48 hours of your test. Your doctor's office also receives the results and will contact you if they need to discuss them with you.

What if I miss my appointment?

Contact Labcorp as soon as possible to reschedule. You can do this through Labcorp.com or by calling 1-800-522-2676. Repeated no-shows may affect your ability to schedule future appointments at some locations.
