About Us

Why Choose Sonora Quest Laboratories?

Does it matter that your health plan lets you and your doctor choose your diagnostic laboratory?

Most of us don't think much about which diagnostic lab we use. The fact is that healthcare decisions made by doctors include lab results about 75% of the time. It makes sense to want the best possible team behind you. We think selecting a health insurance plan that lets you and your doctor make the choice is so important that we tell people about it — because it matters.


Why does it matter which lab I choose?

Sonora Quest Laboratories performs more routine and specialized tests than any laboratory in Arizona. Through our integrated laboratory network, we see many complex cases that allow us to build a foundation of expertise unavailable at other laboratories. We are local laboratories, with a local focus, continually investing in the Arizona community with laboratories in the Phoenix and Tucson metropolitan areas, as well as in Flagstaff, Prescott, and Yuma.

Our high volume of testing performed within our laboratory network (more than 57 million diagnostic tests each year) allows us to develop dynamic systems that help to streamline processes and improve quality. In fact, we were the first healthcare establishment to be awarded with the Arizona Governor's Award for Quality in 2005, and the first company to earn this distinction since 2001. No organization has attained this award since. The Governor's Award for Quality recognizes organizations that have mature and fully-developed quality systems within their operations; that demonstrate a commitment to continuous improvement and have achieved a sustained significant record of performance. Leading up to the Arizona Governor's Award for Quality, we were also distinguished with two 2004 Arizona Showcase in Excellence Awards as well as the 2003 Arizona Pioneer Award for Quality. Since the awards listed above, we were presented with an Arizona Showcase in Excellence Award in 2007, named one of the Best Places to Work in Arizona by the Phoenix Business Journal seven consecutive years, most recently in 2014, and named a winner of the Better Business Bureau of Greater Arizona's 2011 Business Ethics Award.

When selecting a physician, you want someone who is well trained and experienced. Your physician wants a lab that is equally well trained and experienced, and so should you. These are just a few of the reasons Sonora Quest Laboratories is the leading diagnostic testing laboratory in the state of Arizona and why it matters which lab you and your physician choose.


How do I know the results from my lab are accurate?

Sonora Quest Laboratories' staff of affiliated physicians and clinical scientists supports the quality of testing and assist physicians with test selection and interpretation. These M.D.s and Ph.D.s include specialists in pathology and laboratory medicine, endocrinology, oncology, coagulation, medical genetics, and many other areas of sub-specialization. We encourage collaboration. Your physician has direct access to these experts to discuss new tests as well as patients with challenging medical conditions. Sonora Quest Laboratories also routinely educates physicians on advances in medicine and laboratory testing and offers genetic counseling with physicians to work directly with them in test selection and result interpretation.

Sonora Quest Laboratories adheres to the highest standards of clinical laboratory operations, quality assurance and control. All of our laboratories are fully accredited by the College of American Pathologists, and certified by federal and state agencies. We scored >99% in proficiency testing for our laboratories with our goal being 20 times more stringent than the College of American Pathologists' goal of 80%. We continue to strive to meet the highest standards of laboratory services for our patients and their physicians. Sonora Quest Laboratories was the first laboratory in Arizona to introduce Six Sigma quality to the healthcare services field in 2000. What does this mean to you, the patient? These systems bring together employees at all levels of the organization with the goal of improving quality.

Sonora Quest Laboratories has a dedicated staff of quality experts who are fully devoted to teaching and enhancing quality. The goal is to provide a seamless process with a goal of error-free work. We strive to treat every patient specimen as though it came from a loved one. The patient comes first in everything we do.


How far will I have to drive for testing? And how long will I have to wait once I get there?

With 70 Patient Service Centers located statewide, you shouldn't have to spend a lot of time traveling. You also want to spend less time in a waiting room. We realize your time is valuable, so we offer online appointment scheduling so that you can schedule a date and time that is convenient for you for your next Patient Service Center visit. Otherwise you can just drop by a Patient Service Center when you have a free moment. We're committed to serving all of our patients as promptly as possible. Our busiest times are in the morning, so if your schedule permits an afternoon visit, this should help cut down on your wait time. Also note that several of our Patient Service Centers are open on Saturday.

Is my lab using the latest innovations and new technology?

In addition to the broadest array of standard and esoteric, or rare, tests available from any laboratory in Arizona, Sonora Quest Laboratories has taken the lead in offering new kinds of tests that improve results or make testing easier for patients. Our ImmunoCAP® test requires only a single blood sample to pinpoint, with 96-98% accuracy, hundreds of specific allergies that can lead to asthma and other allergy-related diseases, replacing those older, painful scratch tests. Focus Diagnostics, who is in our affiliated laboratory network, is recognized worldwide for its leadership in infectious and immunologic diseases and has established a reputation for being first to introduce new assays to the market, including diagnostic tests for Lyme disease, West Nile Virus, SARS, and H1N1. Sonora Quest Laboratories also performs more types of routine and specialized tests than any laboratory in Arizona. In the area of women's health and oncology, we evaluate more than 280,000 Pap tests a year and offer a full range of tests for HPV - the leading cause of cervical cancer.

Through one of our parent companies, Quest Diagnostics, a wealth of information is available on-line, including information on frequently ordered lab tests and an "Ask the Doctor" checklist.


What if my doctor wants follow-up testing?

Sonora Quest Laboratories keeps many samples after initial testing, so follow-up tests can often be performed on the same sample if your doctor requires it. That's particularly important when results indicate that additional testing may be beneficial. This saves you and your doctor the valuable time that it would take for you to have to be recollected.


Have you committed to high service standards - in writing?

Regulations for phlebotomists, the formal job title for people who draw blood, are inconsistent from state to state. That's why Sonora Quest Laboratories established its own Phlebotomy Code of Conduct and Patient Service Gold Standards - to help ensure that Sonora Quest Laboratories´ more than 750 phlebotomists statewide consistently deliver superior service to our patients during each and every visit. Every Sonora Quest Laboratories patient service center displays both the Code of Conduct and Patient Service Gold Standards for all patients to see. Ask your phlebotomist about them. We're proud to follow these Standards.


What can you do to help me and my child deal with our fear of needles?

We know how scary sample collection can be for some children and adults. You should use a lab whose goal it is to put patients first — including children. That's why every Sonora Quest Laboratories technician is trained to make sample collection as efficient and pain-free as possible. More than 160,000 patients visit Sonora Quest Laboratories´ patient service centers each month. They keep coming back, in part, because of the high quality standards adhered to by our more than 750 professional phlebotomists.


How do you ensure the confidentiality of my personal health information?

As Arizona's leader in diagnostic laboratory testing, Sonora Quest Laboratories is committed to the highest standards when it comes to protecting the confidentiality of personal health information. Sonora Quest Laboratories is committed to meeting the privacy and security requirements of HIPAA (Health Insurance Portability and Accountability Act). This includes strict policies and practices desinged to help protect confidential information and limiting access of confidential information to certain employees. For more information, please see our Privacy Policy.


How quickly can I get my results?

We know that waiting for laboratory results causes anxiety and worry. Sonora Quest Laboratories has created goals for what we term "turnaround time," the time it takes from when we draw your sample until the laboratory produces results for physicians to interpret and diagnose. That's why we created a goal that ensures your doctor gets your results for most tests the very next morning. In fact, 90% of routine testing is reported to physicians by 8:00 A.M. the following morning.

Sonora Quest Laboratories has one of the largest fleets of delivery vehicles in the state. We have over 110 couriers making approximately 85,000 stops each month, picking up specimens throughout the state, and transporting them quickly and safely to our local facilities that can test specimens rapidly. Couriers drive day and night, in mild and inclement weather, to assure prompt delivery to our testing laboratories.

Sonora Quest Laboratories continues to invest in electronic connectivity between our laboratories and physicians, reducing the time it takes to deliver results. Connectivity allows physicians to order tests and receive test results electronically with greater speed than ever before. And we continue to invest in our Information Technology solutions. Our electronic test order and results system allows physicians to review lab results and order prescriptions electronically in a matter of seconds. Quality and Collaboration are two of our core values that come to life in our connectivity solutions.


Can you help me understand my test results and how they impact my overall health?

Sonora Quest Laboratories and our affiliated laboratory network have a wealth of diagnostic testing knowledge and expertise. We continually post patient education materials regarding various tests and how patients can interpret their results. In addition, we also post testing recommendations from such agencies as the Center for Disease Control (CDC) and the Arizona Department of Health Services. We also provide patient literature brochures at all of our Patient Service Centers throughout the state and in some of our client's offices. You can also use the Learn About Lab Tests tool throughout our web site to learn more about various lab tests. Additional information to help you gain a better understanding of your laboratory testing is made available to you through our parent company, Quest Diagnostics, at their destination: Health website. Here, we'll help you map out the best plan for the healthy life you (and your family) want.
