How to Schedule a Labcorp Appointment by Phone

The main Labcorp scheduling number is 1-800-LAB-CORP (1-800-522-2676)

Call this number during business hours — typically 7 a.m. to 7 p.m. Monday through Friday, and 8 a.m. to 4 p.m. Saturday — to book an appointment at any Labcorp location. A representative will ask which location is most convenient for you, what type of test your doctor ordered, and what times work with your schedule. They can usually book you same-day or next-day if the location has availability.

Have your insurance card and doctor's order ready when you call. If you don't have a doctor's order yet, the representative can tell you whether you need one before your visit or whether you can arrange it at the location. Some tests require fasting or other preparation, and the representative will tell you what applies to your specific test.

If you're calling from outside the United States, check the Labcorp website for your country's phone number, as the 1-800 number only works from within the U.S.

Key Takeaways

• The main Labcorp phone number is 1-800-522-2676, and representatives can book appointments for any location during standard business hours.
• Have your insurance card and doctor's order available before calling, though you may be able to arrange the order at your appointment if needed.
• The representative will tell you about any preparation required for your specific test, such as fasting or avoiding certain foods.
• If you need an appointment outside standard hours or prefer not to call, Labcorp also offers online scheduling through their website.

What to have ready before you call

Gather your insurance information first. The representative will need your member ID and group number, which appear on your insurance card. If you don't have insurance or plan to pay out-of-pocket, let them know — Labcorp can still schedule you and will quote the cost.

You'll also need your doctor's order, which is the lab requisition your doctor sent to Labcorp or gave you to bring. This document tells Labcorp which tests to run. If your doctor hasn't sent it yet, ask the representative whether you can pick it up at the location or whether your doctor needs to send it before your appointment.

Have a list of locations near you, or be ready to tell the representative which area is most convenient. Labcorp has thousands of patient service centers across the country, so there's usually one within a few miles.

What happens during the phone call

The representative will start by asking your name, date of birth, and contact information. They'll confirm your insurance details and ask what type of test you need — for example, a lipid panel, drug screening, or COVID-19 test. They may ask whether you've been to Labcorp before, because returning patients sometimes have faster check-in.

Next, they'll show you available time slots at locations near you. You can choose the date and time that fits your schedule. The representative will confirm your appointment and may give you a confirmation number — write this down or ask them to email it to you.

Before you hang up, ask about any preparation your test requires. Some blood tests need you to fast (not eat or drink anything except water) for 8 to 12 hours beforehand. Others have no restrictions. The representative will tell you exactly what applies to your test and what time you should arrive.

Preparation instructions the representative will mention

Different tests have different requirements. A fasting blood test means no food or drink except water after midnight the night before, and you should schedule your appointment for early morning. A non-fasting test has no food restrictions. Urinalysis usually requires no preparation at all.

Some tests ask you to avoid certain medications or supplements for a period before your visit — for example, biotin supplements can interfere with some hormone tests. The representative will tell you if this applies to your test. If you're unsure whether a medication you take will affect your results, ask the representative or call your doctor before your appointment.

Bring a photo ID and your insurance card to your appointment. If you're under 18, a parent or guardian must be present. Arrive 10 to 15 minutes early to allow time for check-in.

If you can't reach someone by phone

Labcorp's website has an online scheduling tool where you can book an appointment without calling. Go to labcorp.com, select "Schedule an Appointment," enter your location and preferred date, and choose from available time slots. You'll need your doctor's order number or your doctor's name and phone number so Labcorp can retrieve your order.

Online scheduling is available 24 hours a day and often faster than calling during busy times. You'll receive a confirmation email with your appointment details and any preparation instructions specific to your test.

If you have questions after scheduling online or by phone, you can also use Labcorp's online chat feature on their website during business hours, or email their customer service team.

What to expect at your appointment

Arrive at least 10 minutes early. Check in at the front desk with your ID and insurance card. A phlebotomist will call you back to the collection area, verify your name and date of birth, and ask whether you've had any recent fainting or difficulty with blood draws. Tell them if you have — they can take extra precautions.

The actual blood draw takes a few minutes. The phlebotomist will clean your arm, insert a needle into a vein, and collect the amount of blood your test requires. You'll feel a pinch when the needle goes in, but most people describe it as quick and not painful. After the draw, they'll apply a bandage and you're done.

Results typically come back within 24 to 48 hours. Labcorp will send them to your doctor, and your doctor's office will contact you with the results and what they mean. Some results are available through your patient portal the same day.

Frequently Asked Questions

Can I schedule an appointment for someone else?

Yes, you can call on behalf of a family member or friend, but Labcorp will need their name, date of birth, and insurance information. If the person is a minor, a parent or guardian must be present at the appointment. Some locations allow you to schedule for an adult without their permission, but it's best to confirm with them first.

What if I need to cancel or reschedule?

Call the same number (1-800-522-2676) to cancel or change your appointment. You can also reschedule online through the Labcorp website. If you need to cancel, do it at least a few hours before your appointment so the time slot can open for someone else.

Do I need a doctor's order to get tested?

Most tests require a doctor's order, but Labcorp offers some tests directly to consumers without a doctor's order — these are called "direct access" tests and include things like wellness panels and STI screening. Ask the representative whether your test is available as direct access, or check the Labcorp website.

What if my insurance doesn't cover the test?

The representative will tell you the out-of-pocket cost before you schedule. Labcorp accepts most major insurance plans, but coverage depends on your specific plan and whether your doctor ordered the test as medically necessary. If cost is a concern, ask whether a less expensive alternative test might work for your situation.

Can I get results by phone?

Labcorp typically sends results to your doctor, who will contact you. You can also view results online through your patient portal if you create an account on the Labcorp website. Some locations will discuss basic results over the phone, but your doctor should interpret what the results mean for your health.
