Trends and Insights
Personalized testing demand is pushing labs to scale up, partner and consolidation
- The personalized healthcare trend is accelerated adoption of advanced diagnostics and more convenient testing, which is raising technology, data and talent requirements. As capabilities become more complex and expensive, larger lab networks are generally better positioned to fund new platforms and integrate acquisitions, reinforcing consolidation strategies. For example, Roche completed its acquisition of LumiraDx’s Point of Care technology in July 2024 to expand decentralized testing access, strengthening its competitive position in point-of-care diagnostics.

Trends and Insights
Dark-lab adoption hinges more on ROI and integration than technology
- Dark labs are highly automated diagnostic laboratories designed to operate with minimal routine human intervention. They are poised to expand as laboratories seek to relieve staffing pressure and improve turnaround times. These facilities are increasingly valuable because robotics and AI can handle sample preparation, processing and even portions of result handling, reducing human error risks such as mislabeling and transcription errors.
