How to Fax a Medical Records Release to Labcorp
Labcorp releases a patient's laboratory test results and related records against a signed authorization, and it runs a patient records-request process for exactly that. Lab results are protected health information, so a signed release directs Labcorp on which results to disclose and to whom. This guide covers what the authorization must contain, how to confirm the current records-request destination, and how the Labcorp Patient portal fits in as a self-service option for a patient's own results.
Does Labcorp accept a fax?
Yes — Labcorp accepts a signed authorization to release lab test results and related records, processed through its patient records-request channel. Because results are protected health information, a written, signed release is what tells Labcorp exactly which tests to disclose and the person or organization authorized to receive them.
Finding the official fax number
Confirm where a signed release should be sent using the records-request or authorization details on Labcorp's own site, or use the destination printed on Labcorp's authorization form. Verify the current number before faxing, since lab results are protected health information and must reach the correct records-request team.
What to include on every page
- The patient's full name and date of birth as they appear in Labcorp's system
- The specific tests or results and the date range being requested
- The name and address of the person or organization authorized to receive results

Recent updates
Federal interoperability rules keep pushing healthcare past the fax machine
CMS has advanced a series of interoperability rules that press hospitals, payers, and providers toward electronic data exchange and standardized claims attachments. The direction of travel is clear: paper and analog fax workflows are being replaced by digital transmission that carries an auditable record — which is exactly what a cloud fax with delivery confirmation provides for offices not yet on a full EHR pipeline.
CMS →Healthcare breach reporting keeps document handling under scrutiny
Ongoing reporting on HIPAA breaches and OCR settlements underscores how much scrutiny falls on how medical documents are stored, sent, and received. Sending records through a controlled, access-logged channel rather than an unmanaged machine reduces the mishandling risks that show up repeatedly in breach analyses.
HIPAA Journal →HHS OCR continues enforcing HIPAA safeguards on how PHI is transmitted
The HHS Office for Civil Rights enforces the HIPAA Security Rule's requirement that covered entities apply administrative, physical, and technical safeguards to protected health information in transit. Faxing PHI is permitted, but the sending practice is responsible for confirming the destination and controlling access — the reason healthcare senders favor a channel that logs each transmission and its recipient.

Faxing Medical Records Release Authorization (HIPAA Authorization Form) to Labcorp — FAQ
Labcorp accepts a signed authorization to release lab test results and related records, processed through its patient records-request channel. Because results are protected health information, a written, signed release directs Labcorp on exactly what to send and to whom.
You have options. The Labcorp Patient portal lets a patient view and download many of their own lab results directly, while a signed authorization sent to the records process is how a third party obtains results or how you request records the portal doesn't display.
Labcorp maintains its own authorization for releasing test results, and completing that form is the cleanest route because it asks for the patient identifiers, the tests or date range, and where to send the results. It captures what Labcorp's records staff need to act on the request.
How fast Labcorp releases results after receiving a complete authorization depends on the request and the number of tests involved. A specific request — naming the tests or a tight date range — is generally fulfilled faster than an open-ended one covering everything on file.
