Laboratory Corporation Of America

Laboratory Corporation of America, operating as Labcorp, is the federal government's largest single-source provider of clinical laboratory and reference testing services, competing as a pure prime contractor in full-and-open procurements with no SBA set-aside designations across a portfolio dominated by the Indian Health Service. The company is a for-profit subsidiary of Laboratory Corporation of America Holdings, headquartered in Burlington, North Carolina, and operates across NAICS 621511 (Medical Laboratories) and PSC codes dominated by Reference Laboratory Testing and Medical-Pathology services.

Labcorp's federal work centers on referral clinical laboratory testing, anatomic pathology, cytology, histology, urinalysis, blood analysis, and specialized diagnostic testing for healthcare delivery. The Indian Health Service represents the vendor's largest customer by both volume and dollars, accounting for 415 awards valued at $161.1 million combined potential value across five active indefinite-delivery contract vehicles, including a $30 million single-award IDV for referral clinical laboratory testing across Navajo Nation facilities and a $9.84 million single-award IDV for area-wide reference laboratory testing across Billings Area IHS facilities in Montana and Wyoming. Representative prime work includes a $2.38 million delivery order from IHS for Navajo Area referral clinical laboratory testing services at Shiprock, New Mexico (awarded March 2025); a $2.8 million Centers for Disease Control and Prevention contract for residual blood specimen collection and SARS-CoV-2 serology testing under the Multistate Assessment of SARS-CoV-2 Seroprevalence study (awarded March 2022); and a $5.03 million Veterans Integrated Service Network 19 BPA call for reference laboratory testing services supporting VA facilities in the Salt Lake City region (awarded October 2022).

Customer concentration is pronounced. The top three funding agencies—IHS, Veterans Integrated Service Network 2, and Veterans Integrated Service Network 19—account for $249.9 million combined potential value across 461 awards, or 51% of the portfolio's total dollars. Across the broader Department of Veterans Affairs footprint, Labcorp maintains significant IDV and BPA relationships, including a $52.5 million single-award IDV with Veterans Integrated Service Network 2 for laboratory urinalysis testing supporting research projects (awarded September 2024) and a $5.03 million BPA with Veterans Integrated Service Network 19. The top five customers by potential value cover 53% of combined potential value, indicating concentration risk anchored to healthcare-delivery relationships.

Labcorp holds five material parent vehicles. The $30 million Navajo Nation referral clinical laboratory testing IDV with IHS (effective through March 2026) and the $9.84 million Billings Area reference laboratory testing IDV (effective through March 2027) are the largest. Federal Supply Schedule V79793DP0018 carries 101 task orders worth $3.3 million combined potential value. The $52.5 million Veterans Integrated Service Network 2 IDV (awarded September 2024, effective through May 2027) and a $5.03 million Veterans Integrated Service Network 19 BPA (awarded October 2022) establish the vendor's footprint within VA healthcare networks. Labcorp also operates under a $400,000 BPA with the Department of the Army for medical readiness laboratory services supporting the Idaho Army National Guard (awarded August 2022, effective through August 2027).

Activity has remained steady in recent years at 17–37 awards annually from 2022 through 2026, reflecting a mature, established market position rather than growth trajectory. Twenty-two awards with combined potential value of $8 million complete within the next twenty-four months, presenting moderate recompete exposure concentrated in IHS and Veterans Health Administration task orders.

SCI-reported invoiced revenue on federal service contracts above the $150,000 threshold totaled $57.7 million across fiscal years 2022–2025, declining from $51.6 million in FY2022 to $1.2 million in FY2024 and zero reported in FY2025, reflecting the shift of contract work below or outside SCI reporting scope or completion of large multi-year vehicles. The SCI dataset shows approximately 76 FTEs delivered to federal government in FY2022, declining to 0.7 FTEs in FY2024. On federal services contracts captured in SCI, government-paid rates ran around $784 median hourly, with senior labor pricing through $1,681/hr and lower-cost labor at $602/hr. Labcorp operates as a pure prime on its healthcare-delivery portfolio with no meaningful subcontractor engagement; across SCI-reportable prime contracts, the average sub-hours share was zero percent.

The vendor maintains named subsidiaries including Visiun, Inc., Medical Neurogenetics, LLC, Medtox Laboratories Inc., and Medtox Diagnostics, Inc. Labcorp appears as a named subcontractor to Consolidated Nuclear Security, LLC on Department of Energy management-and-operating contracts for Y-12 National Security Complex and Pantex Plant (awarded May 2024 and November 2024), and to Leidos on science operations and maintenance support for the United States Antarctic Program (awarded May 2024). These sub relationships are limited in scope and do not materially shape the vendor's primary federal profile, which is anchored to direct prime delivery of laboratory services to health agencies.
