About Histo-Scientific Research Laboratories & Vet Path Services

Histo-Scientific Research Laboratories (HSRL) and Vet Path Services (VPS) have merged to become the leading provider of GLP-compliant research and preclinical histology, pathology and specimen archiving services for the biopharmaceutical, medical device and contract research industries.

Established in 1999 and 2005 respectively, HSRL and VPS have long been regarded as two of the most well-respected sources of high-quality histology and histopathology services in the preclinical research and development market. By joining forces, the companies are able to build upon their equally robust and complementary portfolios of services, which include tissue analysis, efficacy determination for new compounds and devices, toxicological evaluation of products subject to FDA approval, detailed pathology reporting for GLP studies, medical device pathology and immunohistochemistry.

With this merger, HSRL and VPS operate three state-of-the-art sites in the US, with substantial continued investment in facility and technology infrastructure to meet the growing demand for high-quality histopathology services. The new combined entity has more than 20 board certified veterinary pathologists and over 50 laboratory technicians on staff supporting a unified commitment to quality, scientific integrity and customer service excellence.
