How to Schedule a LabCorp Appointment by Phone

Call LabCorp's appointment line to book a test at your nearest location

The fastest way to schedule a LabCorp appointment by phone is to call 1-800-LAB-CORP (1-800-522-2676). This is LabCorp's main scheduling line, and it operates Monday through Friday, 7 a.m. to 7 p.m. Eastern Time, and Saturday 8 a.m. to 4 p.m. Eastern Time. When you call, have your insurance card and photo ID ready — the representative will ask for basic information like your name, date of birth, and the type of test your doctor ordered.

The representative will ask which LabCorp location works best for you and what times are available. LabCorp has thousands of patient service centers across the United States, so you'll usually have multiple options within a short drive. If you don't know which test you need, have your doctor's order or prescription handy — the representative can look it up by your name and date of birth if your doctor has already sent it to LabCorp.

After you book, you'll receive a confirmation number. Write it down or ask the representative to email it to you. You'll need this number when you arrive at the location, and it helps if you need to reschedule or cancel later.

Key Takeaways

  • Call 1-800-522-2676 to schedule; the line is open weekdays 7 a.m. to 7 p.m. Eastern and Saturday 8 a.m. to 4 p.m. Eastern.
  • Have your insurance card, photo ID, and doctor's order information ready before you call.
  • The representative will help you find a nearby location and available time slot.
  • You'll receive a confirmation number at the end of the call — keep it for your records and bring it to your appointment.
  • If your doctor hasn't sent your order to LabCorp yet, the representative can still schedule you, but the order must arrive before your appointment date.

What information you'll need to provide

When you call, the representative will ask for your full name, date of birth, phone number, and address. They'll also ask for your insurance information — have your insurance card in front of you so you can read the member ID and group number. If you don't have insurance or are paying out of pocket, tell the representative; LabCorp will quote you a price for the test.

You'll also need to tell them what test you're having done. If you have a paper order from your doctor, read the test name directly from it. If you don't have the order with you, you can give the representative your doctor's name and they can search LabCorp's system to see if the order has already been received. If it hasn't arrived yet, you can still book the appointment, but the order must be in the system before you show up.

How to find your nearest LabCorp location

When you call 1-800-522-2676, the representative will ask for your zip code or city and state. They'll then tell you which LabCorp patient service centers are closest to you and what hours they're open. Most locations are open early in the morning (often 6 or 7 a.m.) and stay open into the evening, with some open on Saturday mornings.

If you want to browse locations before you call, you can visit LabCorp's website and use their location finder tool — but calling is faster if you're ready to book right away. The phone representative can tell you wait times at different locations and may be able to suggest a quieter time of day to come in.

Rescheduling or canceling an appointment

If you need to change your appointment time or date, call the same number: 1-800-522-2676. Have your confirmation number ready. The representative can usually move you to a different time slot at the same location or switch you to a different location entirely. Most LabCorp locations allow you to reschedule up to 24 hours before your appointment without penalty.

If you need to cancel instead of reschedule, let the representative know. There's usually no charge for canceling, but it's courteous to cancel as soon as you know you won't be coming so the time slot can open up for someone else.

What to expect when you arrive

Bring your confirmation number, photo ID, and insurance card to your appointment. Arrive 10 to 15 minutes early so you have time to check in. At the front desk, give the staff member your confirmation number and ID. They'll verify your information and may ask you to sign consent forms.

Depending on the test, you may need to fast (not eat or drink anything except water) for a certain number of hours beforehand. The representative who scheduled your appointment should have told you this, but if you're unsure, call back before your appointment date to confirm. Fasting requirements vary by test — some require it, others don't.

If you have questions before your appointment

If you think of questions after you hang up, you can call 1-800-522-2676 again. The representatives can answer questions about fasting, what to bring, how long the test takes, or whether you need to do anything special to prepare. You can also ask about test results — LabCorp usually makes results available online within 24 to 48 hours, and the representative can tell you how to set up an online account if you don't have one.

If your question is about your specific test results or what they mean, you'll need to contact your doctor's office instead. LabCorp performs the test and reports the numbers, but your doctor interprets the results and explains what they mean for your health.

Frequently Asked Questions

Can I schedule a LabCorp appointment without insurance?

Yes. Tell the representative you're paying out of pocket, and they'll quote you a price for the test. LabCorp's cash prices are often lower than what insurance companies pay, so it may be worth asking even if you have insurance.

What if my doctor's order hasn't reached LabCorp yet?

You can still schedule the appointment. The order must arrive in LabCorp's system before your appointment date, but it doesn't have to be there when you call. Ask the representative how long it usually takes for orders to arrive from your doctor's office.

Can I schedule multiple tests at the same appointment?

Yes, if your doctor ordered multiple tests. Tell the representative all the tests you need, and they can schedule them all for the same visit. You'll usually have one appointment time and one check-in, even if you're having several different tests done.

Do I have to fast before my appointment?

It depends on the test. Some tests require fasting (usually 8 to 12 hours), others don't. The representative will tell you when you schedule. If you're unsure, call back before your appointment to confirm — it's better to ask than to show up unprepared.

How long does it take to get my test results?

Most LabCorp results are available online within 24 to 48 hours. You can view them through LabCorp's patient portal if you set up an account, or your doctor's office will receive them and contact you. Ask the representative how to access your results when you schedule.
