Overview

Laboratory & Diagnostic Services covers clinical and anatomic pathology laboratories, genetic-testing providers, and toxicology labs. The reference-lab market is consolidated around Labcorp and Quest Diagnostics, alongside a growing field of specialty and genomic-testing companies.

The segment saw an extraordinary COVID-testing surge in 2020–22 that inflated revenue before normalizing, while the durable growth driver is the expansion of molecular, genetic, and precision-diagnostics testing. It is consolidating, with the majors acquiring hospital outreach labs and specialty testing capabilities.
