About Experimental Pathology Laboratories, Inc.

Experimental Pathology Laboratories, Inc. (EPL) is a for-profit, employee-owned contract research organization headquartered in Sterling, Virginia, specializing in toxicology pathology services. Registered in SAM.gov since 2002 and structured as a Subchapter S corporation, EPL provides advanced scientific and laboratory services to multiple federal agencies. The company has established itself as a critical research partner for government organizations, offering specialized technical capabilities in histology, pathology, and veterinary services across various scientific domains.

EPL has been awarded numerous federal contracts primarily from agencies such as the Environmental Protection Agency (EPA), Centers for Disease Control and Prevention (CDC), National Institutes of Health (NIH), National Institute of Allergy and Infectious Diseases (NIAID), and Department of the Interior Fish and Wildlife Service. Their contract work consistently involves complex scientific research services including histological examination, microscopic tissue evaluation, pathology reporting, and specialized studies involving rodent and human tissue samples. Recent contract work has focused heavily on emerging research areas like perfluoroalkyl substances (PFAS) exposure studies, COVID-19 related histological research, toxicology evaluations, and environmental impact assessments. The majority of their contracts are firm fixed-price purchase orders without specific set-aside designations, suggesting EPL competes effectively in open federal procurement competitions. Notable recent contracts include a $49.8 million cost-plus-fixed-fee contract with the National Institute of Environmental Health Sciences for archives and repository management, and multiple EPA-funded studies examining chemical exposure effects on rodent tissues.
