Sonora Quest is an independently operated joint venture between Banner Health and Quest Diagnostics. It is the largest comprehensive laboratory system in the United States, with approximately 3,200 employees and serving more than 28,000 patients in Arizona every day. It is recognized by the American Association of Pathologists, which is the gold standard recognized by laboratories to help laboratories maintain the accuracy of test results and ensure accurate patient diagnosis. When CAP inspectors check the qualifications, equipment, facilities, safety procedures and records, and overall management of laboratory staff, this accreditation ensures the highest standard of care for all laboratory patients. Sonora Quest has signed contracts with most major health plans and is considered an in-network plan, and offers reduced prices for patients who wish to pay for services due to lack of insurance coverage or high deductibles.
