How to Schedule and Prepare for a LabCorp Appointment

How to schedule a LabCorp appointment

LabCorp lets you schedule appointments online, by phone, or by walking in without an appointment at most locations. The online method is fastest: go to labcorp.com, enter your zip code to find nearby patient service centers, select a location and date, and choose your time slot. You'll need to provide your name, date of birth, phone number, and insurance information if you have it.

If you prefer to call, dial 1-800-LAB-CORP (1-800-522-2677) and a representative will find available times at locations near you. Walk-in appointments are available at most LabCorp patient service centers, though wait times vary by location and time of day. Early morning visits typically have shorter waits.

Before you book, check whether your doctor has already ordered lab work for you. If your doctor ordered tests through LabCorp's system, the tests will be linked to your account when you schedule. If your doctor ordered tests through a different lab or sent a paper requisition, bring that paperwork with you to your appointment.

Key Takeaways

  • LabCorp appointments can be scheduled online at labcorp.com, by calling 1-800-522-2677, or by walking in at most locations without advance notice.
  • You will need your insurance card and photo ID at your appointment, even if you scheduled online.
  • If your doctor ordered tests, bring any paper requisition forms or have your doctor's office send the order to LabCorp before your visit.
  • Fasting requirements depend on which tests you're having, so ask when you schedule or check your test order details online.

What to bring to your LabCorp appointment

Bring a photo ID and your insurance card to every appointment. LabCorp accepts most major insurance plans, but coverage and out-of-pocket costs vary by plan. If you don't have insurance, LabCorp offers self-pay options; ask about pricing when you schedule.

If your doctor gave you a paper requisition form or test order, bring it with you. If your doctor ordered tests electronically through LabCorp, the order will be in the system and you won't need paperwork, but it doesn't hurt to have a copy. If you're unsure whether your order is in the system, call LabCorp before your appointment to confirm.

Wear loose, comfortable clothing with sleeves that roll up easily if you're having blood drawn. This makes it simpler for the phlebotomist to access your arm. If you know you have difficult veins or tend to feel faint during blood draws, mention this when you check in.

Fasting and preparation before your visit

Some blood tests require fasting—usually meaning no food or drink except water for 8 to 12 hours before your appointment. Fasting is most commonly required for tests that measure glucose, cholesterol, or triglycerides. Other tests have no fasting requirement.

When you schedule your appointment online or by phone, you should see which tests are ordered and whether fasting is needed. If the information isn't clear, call LabCorp or your doctor's office to ask. If you fast when it's not required, it won't harm the results, but fasting when it is required is important for accuracy.

If you're taking medications, continue taking them as prescribed unless your doctor told you to stop before lab work. If you're unsure, call your doctor's office before your appointment. Certain medications can affect test results, and your doctor needs to know what you're taking.

What happens during your appointment

When you arrive, check in at the front desk and provide your ID and insurance card. A staff member will verify your information and confirm which tests you're having. If your tests were ordered by your doctor, the order will be pulled up in the system. If you have a paper requisition, hand it over at this time.

You'll be called back to a collection area where a phlebotomist will draw blood, collect urine, or perform whatever test is ordered. The process usually takes 5 to 10 minutes. After collection, you're free to leave. Most results are available within 24 to 48 hours, though some specialized tests take longer.

Results are typically sent to your doctor's office, which will contact you with findings. You can also view many results online through LabCorp's patient portal if you create an account on their website. Ask at check-in if you want to set up online access.

Canceling or rescheduling your appointment

If you scheduled online, you can cancel or reschedule through the same website by logging into your account and selecting your appointment. If you scheduled by phone or in person, call 1-800-522-2677 to make changes. Most locations allow cancellations up to 24 hours before your appointment time.

If you need to reschedule, do it as soon as you know you can't make your original time. This opens the slot for someone else and ensures you get a time that works for you. If you miss an appointment without canceling, you may need to reschedule through the full booking process again.

When results take longer than expected

Most routine blood work results appear within 24 to 48 hours. Specialized tests—such as genetic screening, hormone panels, or cultures—can take 5 to 10 business days or longer. When you schedule, ask how long your specific tests typically take.

If your results are delayed beyond the expected timeframe, contact your doctor's office first, since they received the results before you did. Your doctor can tell you whether results are in and explain any findings. If your doctor's office hasn't received them, they can contact LabCorp on your behalf.

Understanding your bill and insurance

LabCorp bills your insurance company directly for most appointments. Your out-of-pocket cost depends on your plan's deductible, copay, and coinsurance. If you have a high-deductible plan, you may owe the full cost of testing until you meet your deductible.

If you don't have insurance, ask about self-pay pricing when you schedule. LabCorp offers discounts for uninsured patients, and prices vary by test. Some community health centers or urgent care clinics offer lower-cost lab work as an alternative.

If you receive a bill you don't understand, call the number on the bill to ask for an explanation. LabCorp's billing department can break down what each charge is for and discuss payment options if you can't pay in full.

Frequently Asked Questions

Do I need an appointment or can I just walk in?

Most LabCorp locations accept walk-ins without an appointment, though you may wait longer during busy times. Scheduling online or by phone guarantees a specific time slot and usually means a shorter wait. Early morning appointments typically have the shortest wait times.

What if my doctor didn't order tests through LabCorp?

Bring your paper requisition form or any order from your doctor to your appointment. LabCorp can process orders from any doctor or healthcare provider. If you have an electronic order from another lab, call LabCorp before your visit to see if they can access it in their system.

Can I eat or drink before my appointment?

It depends on which tests you're having. Some tests require fasting (no food or drink except water for 8 to 12 hours), while others don't. Check your test order details online or call LabCorp when you schedule to find out whether fasting is required for your specific tests.

How do I get my results?

Results are sent to your doctor's office, which will contact you with findings. You can also view many results online through LabCorp's patient portal if you create an account on labcorp.com. Ask at check-in if you want to set up online access to your results.

What if I can't make my appointment?

Cancel or reschedule through the LabCorp website if you booked online, or call 1-800-522-2677 if you booked by phone. Most locations allow changes up to 24 hours before your appointment. Canceling early opens your time slot for someone else and lets you book a time that works better for you.
