How to Schedule a Labcorp Lab Appointment
How to book a Labcorp appointment online or by phone
You can schedule a Labcorp lab appointment through their website, by phone, or by walking into a patient service center. The online method is fastest — you can book same-day or future appointments in minutes without waiting on hold. You'll need your doctor's order (also called a requisition) before you schedule, since Labcorp won't process lab work without one.
To book online, go to labcorp.com and click "Schedule a Test" at the top of the page. Enter your zip code to find nearby locations, pick a date and time that works for you, and answer basic health questions. You can upload your doctor's order during booking or bring it with you on the day of your appointment. If you prefer to call, dial 1-800-LAB-CORP (1-800-522-2677) and a representative will find available times and confirm your appointment over the phone.

What information you need before you schedule
Gather these items before you start booking: your doctor's order (the paper or electronic form your doctor sent to Labcorp), your date of birth, your insurance information, and your contact phone number. If you don't have your doctor's order yet, contact your doctor's office and ask them to send it to Labcorp. Some offices fax it directly; others email it to you so you can upload it yourself.
If your doctor ordered the test through an electronic health record system, Labcorp may already have it on file. When you schedule online, the system will search for any pending orders under your name and date of birth. If the order appears, you can proceed with booking. If it doesn't show up after a few minutes, call your doctor's office to confirm they sent it and get the order number.
Uploading your doctor's order during online booking
When you schedule through labcorp.com, you'll reach a screen asking whether you have your order ready. If you do, you can upload a photo or PDF of it right then. Use your phone camera to photograph the paper order, or if your doctor emailed it to you, save that file and upload it. Labcorp's system accepts JPG, PNG, and PDF files.
If you don't have the order yet but want to find a time slot, you can complete the booking without uploading it and bring the paper copy to your appointment instead. Labcorp will match you to your order when you arrive. However, uploading ahead of time speeds up check-in and reduces the chance of a mix-up.
Finding a Labcorp location near you
Labcorp operates thousands of patient service centers across the United States. To find one, enter your zip code on labcorp.com or use the location finder tool. The search results show hours, address, phone number, and which tests each location offers. Most centers handle routine blood work, drug screening, and common tests. Some specialized locations offer additional services like imaging or pathology.
If you're scheduling online, the system automatically shows only locations that have availability for your chosen test on your preferred date. If no times appear, try a different date or a location a few miles away. You can also call 1-800-522-2677 to ask about locations that may have sooner appointments or to request a specific center.
What to bring and what to expect on appointment day
Bring your photo ID, insurance card, and doctor's order (if you didn't upload it online). Arrive 10 to 15 minutes early to allow time for check-in. At the front desk, staff will verify your identity, confirm your insurance, and ask you to sign consent forms. If you uploaded your order, they'll pull it up in their system. If you brought a paper copy, they'll scan it and add it to your file.
After check-in, a phlebotomist will call you back to the draw station. The process usually takes 5 to 10 minutes. You'll sit in a chair, the phlebotomist will clean your arm with an alcohol wipe, insert a needle to draw blood into collection tubes, and explore a bandage. Most people feel only a brief pinch. Once the draw is complete, you're free to leave. Results typically post to your online account within 24 to 48 hours, depending on the test.
Canceling or rescheduling your appointment
If you need to cancel or move your appointment, log into your Labcorp account on their website and select "Manage Appointments." You'll see your scheduled test with options to reschedule or cancel. You can also call 1-800-522-2677 to make changes over the phone. Cancellations made at least 24 hours before your appointment time don't incur a fee. If you cancel with less notice, some locations may charge a cancellation fee, though this varies.
If you miss your appointment without canceling, Labcorp may charge a no-show fee. If you're running late, call the location directly to let them know you're on your way — many will hold your time slot if you arrive within 30 minutes of your scheduled time.
Frequently Asked Questions
Do I need an appointment or can I just walk in?
Most Labcorp patient service centers accept walk-ins without an appointment. However, wait times for walk-ins vary widely depending on the location and time of day. Scheduling ahead guarantees your time slot and usually means a shorter wait. If you walk in, bring your doctor's order, photo ID, and insurance card.
What if my doctor's order doesn't show up in the system?
Contact your doctor's office and confirm they sent the order to Labcorp. Ask for the order number or fax confirmation. You can also bring a paper copy of the order to your appointment — Labcorp staff will scan it and add it to your file. If there's a delay, you may be able to reschedule once the order arrives.
Can I schedule a Labcorp appointment for someone else?
You can schedule an appointment for a minor child or dependent adult using their information, but the person being tested must bring their own photo ID to the appointment. For minors, a parent or guardian must be present during the appointment. Call 1-800-522-2677 if you have questions about scheduling for someone else.
How long does a Labcorp appointment usually take?
Check-in takes 5 to 10 minutes, and the actual blood draw takes another 5 to 10 minutes. Total time is usually 15 to 30 minutes, though wait times can add to this depending on how busy the location is. Scheduling an appointment during off-peak hours (mid-morning or mid-afternoon on weekdays) typically means shorter waits.
What if I'm fasting for my appointment?
If your doctor ordered fasting labs, don't eat or drink anything except water for 8 to 12 hours before your appointment. Schedule your appointment for early morning if possible, since fasting is easier overnight. Bring water with you and eat a light snack after your blood draw to help you feel better.
