Diagnostic Laboratory of Oklahoma

Diagnostic Laboratory of Oklahoma is an Oklahoma-based clinical diagnostic laboratory services company that provides routine and esoteric testing for physicians, hospitals, health systems, and patients across the state. The company operates as a joint venture between Quest Diagnostics and INTEGRIS Health and serves as Quest's affiliated laboratory presence in Oklahoma. Its service menu includes routine blood testing, anatomic pathology, and molecular and genetic testing, supported by a statewide network of patient service centers and hospital relationships.
