How to Schedule and Prepare for a LabCorp Appointment

How to schedule a LabCorp appointment

You can schedule a LabCorp appointment online, by phone, or by walking in without an appointment. The online method is fastest: go to labcorp.com, enter your zip code to find the nearest patient service center, and select an available time slot. Most centers let you book same-day or next-day appointments this way. If you prefer to call, dial 1-800-LAB-CORP (1-800-522-2677) and a representative will find an opening near you and confirm the date and time.

Walk-in appointments are available at most LabCorp locations during their posted hours, though wait times vary. If you have a doctor's order for specific tests, bring it with you or have your doctor send it directly to LabCorp before your visit — this speeds up check-in. You do not need an appointment to get lab work done, but scheduling one usually means a shorter wait.

Key Takeaways

• Schedule online at labcorp.com, by phone at 1-800-522-2677, or walk in without an appointment at any patient service center.
• Bring a photo ID, insurance card, and any lab order from your doctor; if your doctor hasn't sent the order yet, ask them to do so before you arrive.
• Some tests require fasting (no food or drink except water for 8 to 12 hours before), so confirm with LabCorp whether your specific tests need it.
• Results typically arrive within 24 to 48 hours and are available through your online LabCorp account or by calling the center.
• If you do not have insurance, LabCorp offers cash-pay pricing; ask about it during scheduling or at check-in.

What documents and information to bring

Bring a valid photo ID (driver's license, passport, or state ID) and your insurance card if you have one. If your doctor ordered specific lab tests, bring the written order or ask your doctor's office to send it to LabCorp ahead of time. You can also provide your doctor's name and contact information at check-in, and LabCorp can request the order directly.

If you are a new patient at that location, arrive 10 to 15 minutes early to complete a brief intake form with your medical history and current medications. If you have had lab work at LabCorp before, your information is already in their system and check-in is faster. Write down any medications you take, including over-the-counter ones and supplements, because some can affect test results.

Fasting and other test-specific preparation

Many blood tests require fasting — typically no food or drink except water for 8 to 12 hours before the test. Fasting tests are usually scheduled in the morning so you can fast overnight. Common fasting tests include glucose (blood sugar), lipid panel (cholesterol), and comprehensive metabolic panel. When you schedule your appointment, ask whether your specific tests require fasting. If they do, LabCorp will tell you the exact fasting window.

For non-fasting tests, you can eat and drink normally. If you are unsure whether your tests require fasting, call the center or check your lab order — it will say "fasting required" or "non-fasting." Do not guess; calling takes two minutes and prevents a wasted trip. Some tests also ask you to avoid certain medications or supplements for a day or two beforehand, so read any instructions your doctor gave you or ask LabCorp when you call.

What happens during the appointment

Check-in takes 5 to 10 minutes. A staff member will verify your identity, insurance, and the tests your doctor ordered. You will then wait briefly to be called back to the draw station. A phlebotomist (the person trained to draw blood) will seat you, tie a tourniquet around your upper arm, clean the inside of your elbow with an alcohol pad, and insert a needle into a vein to collect blood into one or more small tubes. The whole process takes 2 to 5 minutes and feels like a quick pinch.

If you are having urine or other non-blood tests, the phlebotomist will give you a collection cup and direct you to a private restroom. For urine tests, you will collect a midstream sample (start urinating, then collect the middle portion in the cup). Once your samples are collected, you are done — you can leave immediately. The phlebotomist will tell you when and how to expect your results.

How and when to get your results

Most LabCorp results are ready within 24 to 48 hours, though some specialized tests take longer. You will receive an email or text notification when your results are available. Log into your LabCorp patient account at labcorp.com to view them, or call the patient service center where you had your test done. Your doctor's office will also receive a copy of the results automatically.

If you do not have an online account, create one at labcorp.com using your email and the phone number or date of birth you provided at check-in. Your account shows all past and current test results, lets you schedule future appointments, and stores your medical history. If you have questions about what your results mean, contact your doctor — they ordered the tests and can explain them in the context of your health.

What to do if you cannot keep your appointment

Cancel or reschedule through the LabCorp website, by calling 1-800-522-2677, or by contacting the specific patient service center directly. Cancellations made 24 hours in advance do not incur a fee. If you cancel with less than 24 hours' notice, some centers may charge a cancellation fee, though policies vary by location.

If you miss an appointment without canceling, your doctor may need to reorder the tests. Call the center as soon as possible to reschedule. If your lab order has an expiration date (many do), confirm that it is still valid before booking a new appointment. Your doctor's office can reissue an order if it has expired.

Costs and insurance coverage

If you have health insurance, LabCorp will bill your plan directly. You may owe a copay, coinsurance, or deductible depending on your plan — ask your insurance company or LabCorp before your appointment if you want to know the exact amount. LabCorp's website has a cost estimator tool where you can enter your insurance information and the test code to see an estimate.

If you do not have insurance, LabCorp offers cash-pay pricing that is often lower than the insurance billed amount. Ask about cash pricing when you schedule or at check-in. Some employers and community health centers also offer discounted lab testing through LabCorp, so check with your workplace or local health department if cost is a concern.

Frequently Asked Questions

Can I eat or drink before my appointment if fasting is not required?

Yes. If your tests do not require fasting, you can eat and drink normally before your appointment. However, avoid heavy meals right before your appointment — they can make you feel lightheaded during the blood draw. Drink plenty of water the day before and the morning of your test; it makes veins easier to find.

What if I am nervous about needles or have a history of fainting?

Tell the phlebotomist before the draw starts. They can seat you in a reclined chair, let you lie down, or have you stay seated for a few minutes after the draw. Bringing a friend, taking slow deep breaths, and looking away during the needle insertion all help. Fainting during blood draws is uncommon but not unheard of — the staff is trained to handle it safely.

How long do LabCorp results stay in my online account?

Results remain in your account indefinitely, so you can access past tests anytime. This is useful for tracking changes over time or sharing results with a new doctor. You can also download or print results directly from your account.

What if my test results are abnormal?

Contact your doctor — they ordered the tests and will interpret the results in the context of your symptoms and medical history. Do not assume an abnormal result means something serious; many results have simple explanations or require follow-up testing. Your doctor will tell you what the next step is.

Can I reschedule my appointment online?

Yes. Log into your LabCorp account, find your upcoming appointment, and select the option to reschedule. You can also call 1-800-522-2677 or contact your local center directly. Online rescheduling is fastest if you already have an account.
