Sonora Quest Laboratories Fax Number — Arizona Lab Orders and Results

Sonora Quest Laboratories is a joint venture between Banner Health and Quest Diagnostics and is one of the largest clinical labs serving Arizona. Its fax handling follows the servicing lab and the ordering provider's account, so test results are faxed to the number registered for that clinician rather than through a single public line. Requisitions carry the test order, and corrected orders, add-ons, standing orders, or records requests route through the Sonora Quest lab processing the specimen or through client services for your Arizona account. Patients seeking their own results generally use the patient portal instead of a fax.

What You Can Fax to Sonora Quest Laboratories

  • Test order requisitions
  • Add-on and corrected test requests
  • Standing order authorizations
  • Medical-necessity and diagnosis notes
  • Result-copy or records requests for the ordering provider
Tip: Because Sonora Quest primarily serves Arizona providers, confirm your practice's account and its registered result fax with client services before relying on a saved number. Lab results are protected health information, so send through a HIPAA-eligible service like Send FAX Mail's Business plan ($79.99/month) and keep the delivery receipt with the order. Add the patient's name, date of birth, and ordering provider to each requisition.

Faxing to Sonora Quest Laboratories — FAQ

Sonora Quest is a separate Arizona joint venture with Banner Health, so its labs and account setup are distinct from the national Quest Diagnostics operation. Use the Sonora Quest account and servicing lab for Arizona orders rather than a Quest Diagnostics number from another state.

Results are faxed to the number on file for the ordering provider's Sonora Quest account, which client services establishes and can adjust. If results aren't reaching you, verify that registered fax before assuming a general lab line.

Standing and recurring order updates route to the Sonora Quest lab or client services managing your account, which provides the correct fax for order documentation. Include the patient identifiers and ordering provider so the change attaches to the right recurring order.

Yes, patients typically view their results through the online patient portal or a records request rather than by fax. The faxed-result channel is meant for delivery to the ordering clinician, so patient access runs through a different route.
