About DLO

DLO has earned the reputation for being the premier medical laboratory services provider in Oklahoma. This reputation continues to expand on the basis of outstanding service and state-of-the-art technology for clinical laboratory testing.

DLO’s service area encompasses the entire state. The company provides laboratory services—which in some locations includes laboratory management—to a broad cross-section of physicians, hospitals and clinics throughout Oklahoma.

Tremendous resources, superior customer service, and an outstanding staff set DLO apart from its competition. Diagnostic Laboratory of Oklahoma is staffed by Oklahomans who take pride in serving their fellow Oklahomans.
