DLO

What DLO does

Diagnostic Laboratory of Oklahoma (DLO) is a private clinical laboratory services provider operating as a joint venture affiliated with Quest Diagnostics. Founded in 2002 and headquartered in Oklahoma City, DLO serves as the state's premier diagnostic laboratory, operating more than 50 Patient Service Centers and draw sites across urban and rural Oklahoma, supporting over 3,500 physicians and 75+ hospitals with routine blood work, anatomic pathology, and complex molecular and genetic testing. The company's core technology stack — licensed through the Quest Diagnostics JV — includes the Quanum Lab Services ordering and results platform for providers, the MyQuest patient portal, the IntelliTest Manager, and a Virtual Test Guide for specimen collection requirements. Differentiated offerings include the proprietary ANAlyzeR autoimmune panel (25 analytes with ICAP nomenclature) and a Mate Health partnership for at-home male fertility testing analyzing over 20 semen parameters.

DLO's go-to-market operates through two channels. The primary B2B channel is enterprise field sales targeting physician practices and hospital systems across Oklahoma, with electronic test ordering, specimen pickup logistics, and electronic results delivery through Quanum. The secondary DTC channel enables patients to self-order select tests — including perimenopause, post-menopause, and early menopause panels — via QuestHealth without a physician visit. Revenue is generated through insurance reimbursement under contracted in-network rates (transaction-based), supplemented by upfront self-pay options for uninsured or out-of-network patients, and unit-priced self-ordered testing.

Customer segmentation is dual: (i) healthcare providers (3,500+ physicians and 75+ hospitals) who constitute the primary revenue base and order tests via the Quanum platform, and (ii) individual patients accessing PSCs for phlebotomy, urinalysis, COVID-19 screening, self-ordered testing, or at-home fertility collection kits. Operational metrics include an average PSC wait time under 8 minutes and routine result turnaround within 24 hours. Ownership and financial details (revenue, headcount trend, JV economics with Quest Diagnostics) are not publicly disclosed.

Revenue model

1. Clinical Laboratory Testing Services: DLO generates revenue primarily through providing diagnostic laboratory testing services to physicians, hospitals, and other healthcare providers across Oklahoma. Testing encompasses routine blood work, specialized molecular and genetic testing, and anatomic pathology, all delivered through the Quest Diagnostics joint-venture platform.
2. Insurance Billing and Reimbursement: DLO files insurance claims with contracted in-network providers and processes payments from health plans. The company offers upfront payment options for uninsured or out-of-network patients through their Patient Bill Pay system, which includes an Upfront Payment Program.
3. Direct-to-Consumer Testing (QuestHealth): Patients can purchase select lab tests directly through QuestHealth without a healthcare provider order, including menopause and perimenopause testing panels. This provides an additional revenue stream from individual consumers seeking proactive health management.
