How to File a Complaint Against Sonora Quest Laboratories

Patients may need to complain about billing, appointment issues, specimen collection, customer service, test-result access, laboratory service, privacy, or another Sonora Quest experience. Keep the bill, test order, location, appointment date, account information, and any prior support correspondence before escalating.

Step 1: Contact the Patient Service Center or Client Services

If the complaint involves a specific collection location, start with that Patient Service Center. For broader laboratory or provider issues, contact 602-685-5050. Explain what happened, provide the date and location, and ask the representative to document the issue. Keep the name of the representative and any case information provided.

Step 2: Contact Billing Support for Billing Disputes

For billing problems, use the Sonora Quest patient billing portal or the Customer Service information printed on the laboratory bill. Keep the Bill ID, insurance information, Explanation of Benefits, and payment records available. If the laboratory service is processed through Quest billing channels, Quest also publishes 866-697-8378 for billing assistance.

Step 3: Request Supervisor or Management Review

If the initial contact does not resolve the complaint, request escalation to a supervisor or appropriate laboratory-management team. Provide the original location, date, case information, billing details, and a concise timeline. For provider or account issues, use Client Services and the appropriate account-management contact.

Step 4: Send Formal Written Correspondence

For a serious unresolved corporate complaint, correspondence can be directed to Sonora Quest’s Arizona corporate operations at 1255 W. Washington Street, Tempe, AZ 85281 or to the major laboratory facility at 424 South 56th Street, Suite 100, Phoenix, AZ 85034, depending on the nature of the issue. Include copies of bills, appointment records, prior complaints, and supporting documentation.

Step 5: Contact the Appropriate External Authority if Necessary

If the complaint remains unresolved, the proper outside channel depends on the issue. Laboratory-quality or testing concerns may involve the appropriate state health authority, CLIA regulator, or accreditation body. Billing or consumer issues may involve the insurer or applicable consumer-protection agency, while privacy complaints may involve the U.S. Department of Health and Human Services Office for Civil Rights. Keep all records and company responses before escalating.
