Diagnostic Laboratory of Oklahoma

DLO is a joint venture between INTEGRIS Health and Quest Diagnostics, and is the largest clinical diagnostic laboratory in Oklahoma. DLO offers a wide breadth of diagnostics tests and solutions, offering innovation and efficiencies to physicians, hospitals and clinics across the state of Oklahoma. Our fleet of more than 100 vehicles logs more than 9,000 miles each day bringing specimens to our core lab in Oklahoma City to ensure physicians receive rapid results for their patients. In addition, we have 40 conveniently located patient service centers across the state where patients can quickly have their lab tests done.

DLO also offers DLO Direct™, a new program that gives our customers the ability to order select lab tests without a health care provider. We can help you take a more active role in your health through direct access testing with a menu of select lab tests you may request without a health care provider’s order.
