Testing as a Service (TaaS) is the proprietary platform from Quest Diagnostics that enables companies to integrate the sale and delivery of consumer cash-pay diagnostic testing into their own websites, mobile apps, and digital experiences.

Powered by Quest, TaaS gives partners the flexibility to modularize the customer journey and control as much—or as little—of the experience as they choose. Through modern REST APIs and Quest-hosted solutions, partners can seamlessly access curated test panels, compliant payment flows, order submission, appointment scheduling, and real-time order status and results.

By orchestrating medical oversight and results delivery, TaaS helps insulate partners from clinical and regulatory complexity, letting them focus on integrating a lab testing experience into their core product. Quest is the expert at consumer lab testing, and we manage compliance, operations, and infrastructure at-scale.
