Diagnostic Lab Patient Access Point Count measures Quest Diagnostics' broad physical collection footprint, including patient service centers and other access settings.

Quest Diagnostics reported approximately 8,000 access points in its 2025 disclosures.

Patient service centers represented about 30% of access points

Quest reported approximately 2,400 patient service center locations.

Dividing 2,400 by 8,000 gives 30%, implying roughly 5,600 additional access points in other collection settings.

The broader footprint is more than owned service centers

The difference highlights in-office phlebotomy and other collection arrangements that extend beyond dedicated patient service centers.

Use Diagnostic Lab Patient Service Center Count for the narrower physical-location concept.

Access points do not measure throughput

An access point can process very different patient and requisition volumes.

The approximately 8,000 access points therefore describe reach, not utilization or site productivity.

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.
