Insights

Digital Integration Quest Diagnostics has prioritized digital ordering, electronic health record connectivity, and data analytics to strengthen ties with providers and payers. This enables selling enhanced integration services, real-time order transmission, secure data exchange, and advanced reporting that support value-based care models.

Extensive Network With the industry's broadest testing network including labs in major metros, Mexico, UK, and India, plus 2,250 patient service centers and multiple specialty labs, Quest can expand remote specimen collection, point-of-care partnerships, and faster turnaround in underserved markets. This creates cross-sell opportunities for payer programs, employer health initiatives, and rapid-access diagnostic services for clinical trials.

Strategic Partnerships Strategic collaborations across oncology and precision medicine show appetite for joint development and market expansion. Partnerships like City of Hope for Haystack MRD testing, Oura Health panels, and Helio Genomics collaborations signal opportunities to co-develop and co-market new tests within Quest's network, accelerating adoption and expanding reference lab services.

Workplace Screening Quest's leadership in pre-employment drug screening and life insurance risk assessment offers a repeatable revenue engine with enterprise customers. Expanding workplace screening programs, onboarding workflows, and HRIS/EHR integrations can deepen wallet share and drive stickier, recurring revenue across large employers and insurers.

Clinical Trials Enablement Quest is a key partner for clinical trial testing, offering access to a vast lab network and data assets. There is potential to grow pharma-sponsored programs, support biomarker-driven trials, and provide companion diagnostics development and testing, with results integrated into trial platforms and electronic health records.
