Labcorp reports that it performs more than 700 million tests annually for patients around the world and that its laboratory capabilities provided support for more than 75% of the new drugs and therapeutic products approved by the U.S. Food and Drug Administration in 2024. These figures highlight the scale of its testing operations and its role in the development and approval of new therapies.
Diagnostics and clinical testing
Labcorp describes its diagnostics business as offering an extensive menu of clinical and specialty tests. Public statements reference areas such as oncology diagnostics, genetic testing, neurology and consumer-focused testing. The company notes that it has expanded its oncology and genetic testing portfolio, including tests such as OmniSeq INSIGHT and PGDx elio tissue complete, and has made certain genetic tests available through digital health platforms. Labcorp also mentions neurology testing, including blood-based tests related to Alzheimer’s disease, and a range of tests available through its Labcorp OnDemand consumer channel.
Labcorp reports that it operates more than 2,200 patient service centers in the United States, where blood draws and other specimen collections can be performed for ordered tests. It also references agreements to acquire and manage select outreach and reference laboratory assets from health systems and regional laboratories, as well as relationships that expand access to at-home and in-person testing options. Through these activities, Labcorp indicates that it aims to broaden access to high-quality laboratory services for patients and providers.
Oncology and molecular residual disease (MRD) testing
In oncology, Labcorp highlights its Plasma Detect portfolio, a tumor-informed, blood-based assay used to detect molecular residual disease (MRD) from circulating tumor DNA (ctDNA). The company states that MRD testing can help clinicians track a patient’s risk of cancer recurrence by detecting small traces of ctDNA in the bloodstream following treatment, potentially signaling molecular recurrence months before it appears on traditional imaging or causes symptoms.
Labcorp has announced the expansion of its MRD offerings with tests such as Labcorp Plasma Detect ID, a whole exome sequence-guided, personalized panel for certain breast cancer and non-small cell lung cancer patients, and Labcorp Plasma Detect Genome, a whole-genome MRD test for stage III colon cancer. The company notes that its MRD tests are designed to detect ctDNA down to a low limit of detection and that clinical studies have demonstrated their utility in tracking early disease progression, predicting long-term outcomes and identifying residual cancer in contexts such as diffuse pleural mesothelioma and head and neck cancer.
Labcorp presents its oncology diagnostics as supporting cancer care across the continuum, from screening and risk assessment through diagnosis and prognosis, therapy selection, monitoring and surveillance. It also references capabilities in liquid biopsy, tissue-based comprehensive genomic profiling and companion diagnostics, and notes that it partners with oncologists, health systems and biopharma companies to drive precision medicine and expand access to testing.
Neurology and Alzheimer’s-related testing
In neurology, Labcorp has announced that it will offer the Elecsys pTau181 test, a blood test developed by Roche Diagnostics and cleared by the U.S. Food and Drug Administration to aid in the initial assessment for Alzheimer’s disease and other causes of cognitive decline in primary care settings. The company describes this test as measuring phosphorylated Tau (pTau) 181 protein in human plasma, a biomarker associated with Alzheimer’s pathology.
Labcorp notes that the Elecsys pTau181 test is intended for adults with signs, symptoms or complaints of cognitive decline and can help clinicians rule out Alzheimer’s-related amyloid pathology and identify patients who may benefit from further evaluation. The company states that the test is performed via a simple blood draw that can be completed in a doctor’s office or at a Labcorp patient service center, and that it offers a less invasive alternative to traditional cerebrospinal fluid testing or positron emission tomography scans. Labcorp also references a broader portfolio of Alzheimer’s-related tests, including a laboratory-developed pTau181 test and a panel that combines multiple biomarkers.
Biopharma laboratory services and drug development support
Beyond clinical diagnostics, Labcorp reports that it operates a biopharma laboratory services segment that includes central laboratory and early development services. These services support clinical trials and research for biopharmaceutical companies. The company states that its biopharma laboratory services segment provides central lab testing and early development research, and that it tracks metrics such as net orders, backlog and forecast backlog conversion related to this business.
Labcorp’s public disclosures emphasize that its laboratory capabilities supported a large share of new drugs and therapeutic products approved by the FDA in 2024. The company also notes that it has taken steps to refine its early development operations, including divesting or restructuring certain early development revenue and selling select early development medical device testing assets to NAMSA, while focusing on core areas of preclinical drug development and chemical testing.
Scale, reach and partnerships
Labcorp describes itself as serving clients in approximately 100 countries, with a workforce of nearly 70,000 employees. It reports performing more than 700 million tests annually for patients worldwide. The company also highlights its role as a partner to health systems, regional laboratories and consumer health platforms. Examples include agreements to acquire select outreach laboratory assets from Community Health Systems-affiliated health systems, arrangements to acquire assets from other laboratories, and collaborations that make at-home tests available through Labcorp OnDemand and related digital channels.
Labcorp states that it has signed several strategic agreements with health systems and regional or local laboratories, expanded access to genetic tests through electronic health record platforms, and introduced digital tools such as Labcorp Test Finder. It also references investments in digital and artificial intelligence capabilities to enhance areas such as pathology, cytology and microbiology.
