Diagnostic Lab Connected Clinician and Hospital Accounts measures clinician and hospital accounts connected to Quest Diagnostics through its digital and workflow network.

Quest Diagnostics reported approximately 612,000 accounts in its 2025 disclosures.

Connectivity scale was far larger than the physical access footprint

Quest also reported approximately 8,000 patient access points.

Dividing 612,000 connected accounts by 8,000 access points gives roughly 76.5 connected accounts per access point as a scale comparison.

Digital reach and physical access solve different distribution problems

Connected accounts help ordering and results flow through clinician workflows.

Diagnostic Lab Patient Access Point Count measures where patients can physically access collection services.

Connected accounts are not active ordering accounts

The figure measures network reach, not order frequency, requisition volume, or revenue per account.

A connected account can generate very different activity from another account.

Part of the Diagnostic Laboratory Economics

Connect requisition growth and monetization, test and customer-channel mix, and the collection, connectivity, payer-access, and logistics network that supports a large diagnostic laboratory platform.

Where this concept fits

Access, connectivity, and logistics networkCurrent relationship
Patient access points and service centers describe specimen-collection reach, connected clinician and hospital accounts plus insured-lives access describe ordering and payer-network reach, and daily logistics stops plus courier vehicles show the physical transport infrastructure connecting collection sites to laboratories.

Requisition growth and monetization
Test requisition volume is the core activity base, reported and organic requisition growth separate acquisition-driven from underlying volume changes, and revenue per requisition shows monetization across price, payer mix, business mix, test mix, and tests per requisition. Core diagnostic information services and diagnostic solutions revenue keep the two business groups distinct.

Test complexity and customer-channel mix
Gene-based and esoteric testing plus anatomic pathology show important testing-complexity mix, while physician, hospital, and other diagnostic-information-services revenue shares show where demand originates. Test mix and customer channel are separate dimensions of the revenue model.
