Diagnostic Lab Insured Lives Access measures the share of U.S. insured lives for which Quest Diagnostics participates in health-plan networks.
Quest Diagnostics reported access to over 90% of U.S. insured lives in its 2025 disclosures.
Network availability covered at least nine of every ten insured lives
The disclosure implies that fewer than roughly 10% of insured lives fell outside the stated access footprint.
That broad reach reduces network exclusion as a barrier to using Quest, although it does not eliminate patient or physician choice.
Payer access complements physical access
Quest also reported approximately 8,000 patient access points.
Use Diagnostic Lab Patient Access Point Count to separate insurance-network availability from collection-site availability.
Access does not equal utilization or market share
A patient can have network access and still use another laboratory.
The over-90% figure is therefore a distribution-availability measure, not a claim on testing volume.
