While walk-ins are welcome, we recommend scheduling an appointment online to make the experience as smooth as possible. For convenience, appointments are available up to 90 days in advance. Patients can book their own appointments through the MyLabcorp™ mobile app or using the Labcorp Patient™ portal. If you prefer to book an appointment for your patient, we recommend using the Labs & Appointments section of our website.

To book an appointment on behalf of your patient:

• Enter the patient's information and select a convenient location and time
• Provide your patient with the location, date, time, and confirmation number, as they will need these details to manage or change their appointment

We ask that patients arrive 15 minutes early with their test request form (if using a printed order), insurance card, photo ID, and payment method. Patients can explore more detailed preparation tips here to plan for success.

Your patient can easily modify, reschedule, or cancel their appointment through the MyLabcorp mobile app or online using their Labcorp Patient portal. Be sure they have their appointment confirmation number and patient name ready.

Please be aware that children must be supervised at all times at Labcorp patient service centers and cannot accompany patients inside the collection area. We appreciate patients planning accordingly.

High‑dose biotin (vitamin B7) supplements—often used for hair, skin, and nails—can interfere with certain lab tests, leading to falsely high or low results. The FDA has reported serious clinical outcomes related to biotin interference.

Providers should routinely ask patients about biotin use and, when possible, recommend discontinuing supplements several days before testing. More information is available in the FDA’s official biotin interference safety communication.

Workplace drug testing is employer‑ordered and separate from clinical testing. Labcorp provides urine, oral fluid, hair, blood and rapid point‑of‑collection testing at select SAMHSA‑ and CAP‑certified locations.

Employees undergoing testing should bring:

• A chain of custody (COC) form, web COC number or employer testing request
• A valid photo ID

For employer program questions or to coordinate collections for patients with special circumstances (e.g., external urine bags, dialysis), contact Labcorp Occupational Testing Services at 800‑833‑3934 Monday through Friday 8 a.m. to 5 p.m. ET.

Labcorp AccuDraw provides on‑screen guidance for specimen collection. It combines on-screen visual cues with step-by-step tutorials, including the correct order of draw, appropriate tube types and the number of tubes needed. AccuDraw's guidance helps you reduce recollections, prevent specimen contamination and ensure accurate processing.

Visit Labcorp’s Test Resources page for test‑specific requirements, including collection, storage, and handling instructions.

Best practices include:

• Document biopsy collection site and relevant clinical history
• Verify supplies are unexpired prior to collection
• Label specimens accurately with complete patient information
• Provide adequate specimen volume to avoid quantity not sufficient (QNS) delays
• Use the correct container and follow patient preparation and order‑of‑draw requirements
• Transport specimens at required temperatures to maintain integrity

Labcorp provides tools and scientific expertise to support trial matching by diagnosis, disease stage, and biomarker profile.

Providers can:

• Use Labcorp’s “Find a Trial” tool to search active studies by condition or diagnosis
• Leverage biomarker‑driven guidance to support precision‑medicine‑based trial matching and eligibility assessment
• Consult Labcorp’s biomarker‑driven clinical trial programs through the Biomarker Solution Center, which supports trials in oncology, cardiometabolic disease, neurology, and immunology

Labcorp experts can help determine which biomarkers matter most and which trials may align based on disease biology, mechanism of action, and regulatory considerations.

Participation in a clinical trial does not replace routine medical care. Instead, study‑related activities occur alongside your ongoing management.

In most cases:

• You continue to manage the patient’s overall health and non‑study care
• The research team oversees all protocol‑specific activities
• The study coordinator schedules trial visits and communicates relevant updates
• You are informed if any study‑related safety issue requires your involvement

Clear communication between the provider and research team helps ensure continuity of care and patient safety throughout the trial.

As a provider, your primary role is typically to:

• Identify potentially eligible patients
• Ensure clinical information—such as diagnosis, lab results, biomarkers, and medical history—is accurate and complete for screening
• Labcorp Clinical Trial Enablement Services support research teams by providing:
• Data‑driven eligibility analyses
• Inclusion and exclusion criteria assessments
• Patient‑location insights

Tasks such as confirming eligibility, coordinating outreach, managing consent, and guiding patients through enrollment are usually handled by the research team or study coordinator, supported by Labcorp’s analytics and recruitment tools.

Labcorp is a global partner across the entire clinical trial life cycle, helping bring new medications, vaccines, and treatments from research into clinical practice.

With nine central laboratories worldwide, Labcorp processes more than 3 million clinical trial specimens each week and generates more clinical trial data than any other central laboratory network.

Our end‑to‑end support includes:

• Laboratory testing across immunology, genomics, and safety testing
• Global specimen collection and logistics in more than 100 countries
• Consistent quality and regulatory‑aligned processes

Labcorp also supports patients and sponsors through:

• Accurate, reliable testing, including genetic testing and flow cytometry
• Patient‑centered study design informed by eligibility and clinical data
• Accessible study locations to improve participant convenience
• Inclusive outreach to help connect diverse and underrepresented populations to appropriate trials
• High standards for data quality, safety, and compliance
