Diagnostic Lab Gene-Based and Esoteric Testing Revenue Mix measures the share of Quest Diagnostics revenue generated by gene-based, esoteric, and other advanced testing services.

Quest Diagnostics reported 38% of net revenues from this category in its 2025 disclosures.

Advanced testing plus anatomic pathology represented 44% of net revenues

Anatomic pathology represented another 6%.

Together the two testing-complexity categories accounted for 44% of net revenues, indicating that a large portion of revenue came from testing beyond routine clinical work.

Gene-based and esoteric mix was more than six times anatomic pathology mix

The 38% share was approximately 6.3 times the 6% anatomic pathology share.

Use Diagnostic Lab Anatomic Pathology Revenue Mix to keep the two complexity categories distinct.

Higher complexity does not guarantee higher margin

Technology costs, referral economics, specialist labor, payer reimbursement, and test mix can all offset higher nominal pricing.

The revenue share is therefore a service-mix measure, not a direct profitability metric.

Where this concept fits

Test complexity and customer-channel mixCurrent relationship
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.

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.

Access, connectivity, and logistics network
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.
