## What to include in your fax to Quest Diagnostics

Complete the Patient Access Form, identifying the records and delivery recipient. Include proof of representation if the form requires it for someone acting for the patient.

## Check the destination and prepare your cover page

Name the receiving department and the hospital, clinic or service involved. Add the document title, page count and a callback number. Put patient identifiers and authorization details in the fields the official form requests; a cover page does not replace signed consent.

Check the official source and recipient instructions before sending. A reviewed source confirms a published number, not live availability.

## Confirm delivery and follow up with Quest Diagnostics

These are fax destinations, not voice support lines. Keep the transmission result and a copy of the documents. Confirm with the receiving department that the packet is complete and can be processed; a delivery receipt does not establish acceptance or a decision. Check with that department before sending a duplicate.
