Sonora Quest Laboratories

Sonora Quest Laboratories, a subsidiary of Laboratory Sciences of Arizona, is an Arizona-based joint venture between Banner Health and Quest Diagnostics, making up one of the nation’s largest integrated laboratory systems with approximately 3,800 employees. We are the market share leader in clinical laboratory testing in Arizona, performing more than 97 million diagnostic tests per year. We offer a local comprehensive test menu that encompasses routine, molecular, prescription drug monitoring, genetics/genomics, and pathology testing services. Ninety-five percent of all testing is performed at our primary testing facilities located in Phoenix, Tucson, Flagstaff, Prescott, and Yuma.

Sonora Quest Laboratories is accredited by the College of American Pathologists (CAP) which is the gold standard in laboratory accreditation, helping laboratories to maintain accuracy of test results and ensure accurate patient diagnosis. This accreditation ensures the highest standard of care for all laboratory patients as CAP inspectors examine laboratory staff qualifications, equipment, facilities, safety program and record, and overall management.

Sonora Quest Laboratories has more than 70 Patient Service Centers located conveniently throughout Arizona and offers online appointment scheduling on desktop and mobile devices on SonoraQuest.com as a convenience to patients. We are contracted and considered in-network with most major health plans and offer reduced pricing for patients who wish to pay at time of service due to lack of insurance coverage or high-deductibles. We also offer patients a number of ways to obtain their own lab results.
