How to Schedule a Labcorp Appointment Online

You can schedule most Labcorp appointments through their website or mobile app without calling

Labcorp's online scheduling system lets you book lab work directly through labcorp.com or the Labcorp mobile app. You choose your test type, pick a nearby location, select an available time slot, and confirm your appointment — the whole process usually takes five to ten minutes. You'll receive a confirmation email with your appointment details, a barcode to bring or scan at check-in, and any preparation instructions specific to your test.

Not every test can be scheduled online. Certain specialized tests, drug screening programs, and appointments that require a doctor's order may need a phone call to 1-800-LAB-CORP (1-800-522-2767) instead. The website will tell you immediately if your test is available for online booking.

You don't need to be a Labcorp patient already or have an existing account. First-time users create a profile during booking with basic information like name, date of birth, and contact details. If you have insurance, you can enter your member ID during scheduling so Labcorp can verify your coverage before your appointment.

Key Takeaways

• Visit labcorp.com or download the Labcorp app, search for your test type, and choose a location and time slot to book in minutes.
• You'll receive a confirmation email with a barcode and any fasting or preparation instructions you need to follow before your appointment.
• Some specialized tests and drug screenings cannot be booked online and require a phone call to Labcorp's scheduling line.
• Bring your confirmation barcode, insurance card, and a photo ID to your appointment, or scan the barcode at the kiosk if your location has one.
• You can reschedule or cancel through the same website or app up until a few hours before your appointment time.

Step-by-step: booking through the website

Start at labcorp.com and look for the "Schedule a Test" button, usually near the top of the homepage. Click it and you'll land on the scheduling portal. Enter your zip code or city to see nearby Labcorp locations, or search by location name if you know which one you prefer.

Next, search for your test by name — for example, "lipid panel," "COVID-19 test," or "drug screen." Labcorp will show you which tests are available for online booking at each location. Select the test you need and the location closest to you. The system will display available appointment times, usually in 15-minute slots across multiple days. Pick the date and time that works for you.

You'll then enter or confirm your personal information: full name, date of birth, phone number, and email address. If you have a doctor's order or requisition, you can upload it during this step, though many routine tests don't require one. If you have insurance, enter your member ID and group number so Labcorp can check your coverage. You can also choose to pay out-of-pocket if you prefer not to use insurance.

Review your appointment summary and confirm. You'll receive a confirmation email within minutes with your appointment barcode, location address, hours, and any preparation instructions. Save this email or screenshot the barcode — you'll need it at check-in.

Using the Labcorp mobile app

The Labcorp app works the same way as the website but is optimized for phones. Download it from the Apple App Store or Google Play, create or log into your account, and tap "Schedule a Test." The app stores your information and past appointments, so repeat bookings are faster. You can also receive appointment reminders and check your test results through the app if your location offers that feature.

One advantage of the app is that you can save your favorite locations and test types, so the next time you book, those options appear first. The app also lets you check real-time availability and see which locations have the shortest wait times on a given day.

What to bring and how to prepare

Bring your confirmation barcode (printed or on your phone), a photo ID, and your insurance card if you're using insurance. Some tests require fasting or other preparation — Labcorp will email you specific instructions when you book. For example, a fasting glucose test means no food or drink except water for 8 to 12 hours before your appointment. A lipid panel usually requires the same fasting window.

Arrive 10 to 15 minutes early to allow time for check-in. Many Labcorp locations now have self-service kiosks where you can scan your barcode and check in without speaking to staff. If your location doesn't have a kiosk, hand your barcode and ID to the receptionist. They'll verify your information and direct you to the draw station.

If you forget your barcode, staff can look up your appointment by name and date of birth, though having it speeds things up. If you forget your ID, some locations will still draw your blood if you can verify your name and date of birth, but policies vary — calling ahead if you realize this is safer.

Rescheduling or canceling your appointment

You can reschedule or cancel through the same website or app where you booked. Log in, find your upcoming appointment, and select "Reschedule" or "Cancel." Most locations allow changes up to a few hours before your appointment time, though this window varies. If you're within the cancellation window and need to reschedule, you can usually book a new slot immediately.

If you can't reschedule online — for example, if your appointment is very soon — call the location directly or use the main scheduling line at 1-800-522-2767. Staff can often move your appointment the same day if space is available.

When you need to call instead of booking online

Some tests and services require a phone call. These include drug screening programs (especially for employment or legal purposes), certain specialized tests that need a doctor's order, and appointments at specific locations that don't offer online booking. Labcorp's website will tell you immediately if your test or location requires a call.

Call 1-800-LAB-CORP (1-800-522-2767) to speak with a scheduling representative. Have your insurance information and any doctor's order ready. Wait times are usually shortest early in the morning or mid-afternoon on weekdays. If you're calling about a drug screen, be ready to provide details about the type of screen (urine, hair, etc.) and any special instructions from your employer or attorney.

Frequently Asked Questions

Do I need a doctor's order to book a test online?

Most routine tests like lipid panels, glucose tests, and COVID-19 tests do not require a doctor's order. Labcorp will tell you during booking if an order is needed. If you have one, you can upload it during scheduling or bring it to your appointment.

Can I see my test results online after my appointment?

Yes, Labcorp lets you view most results online through your account on labcorp.com or the app, usually within 24 to 48 hours of your appointment. Some results take longer depending on the test type. Your doctor may also receive results directly if they ordered the test.

What if the test I need isn't available for online booking?

Call 1-800-522-2767 and a representative will schedule it for you over the phone. They can often book you the same day or within a day or two, depending on location availability.

Can I change my appointment time after I book?

Yes, you can reschedule through the website or app up until a few hours before your appointment. If you're too close to your appointment time, call the location directly or use the main scheduling line to see if they can move you.

What happens if I don't show up for my appointment?

Labcorp doesn't charge a no-show fee, but if you need the test, you'll have to book again. If you realize you can't make it, cancel or reschedule through the app or website so the time slot opens for someone else.
