Clinical Excellence

Our dedication to advanced technology and world-class quality help increase your diagnostic confidence.


At DLO, we offer a comprehensive testing menu featuring thousands of medical tests. These tests, which range from the routine to the cutting edge of advanced technology, give you the opportunity – and simplicity – of working with just one medical laboratory for all your testing needs.


Through our affiliation with AmeriPath – the national leader in pathology services – we can offer an extensive line of anatomic pathology, dermatopathology and molecular diagnostic services to Oklahoma physicians, hospitals and surgery centers.

Additionally, our locally-based Cytology Center of Excellence offers a complete line of cytology services for you and your practice. This 24-hour facility employs 16 certified Cytotechnologists.


Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects in any process in an organization. To achieve Six Sigma Quality, a process must not produce more than 3.4 defects per million opportunities. In other words, by pursuing Six Sigma Quality, DLO is striving to achieve near-perfection.

Our dedication to achieving this perfection is a continuous process, and it’s exactly why we have an organization of dedicated Six Sigma Black Belts constantly on the lookout for innovative ways to improve quality and eliminate errors. This helps give you the confidence that DLO results meet the stringent standards your practice requires.


At DLO, our expert physicians are always just a phone call away. They offer 24/7 consultation for routine, molecular, genetic and esoteric cases.
