Labcorp Fax Number — Test Orders, Requisitions, and Result Delivery

Labcorp is one of the largest clinical lab networks in the country, and its fax handling is organized around the servicing laboratory and the provider account behind each order. A test order rides on a requisition, and results are faxed to the ordering clinician at the fax number registered on their Labcorp account, so there is no single public results line. For a corrected order, an add-on test, or a records request, the right fax comes from the specific Labcorp lab processing the specimen or from Labcorp client services for your account. Patients wanting their own results generally use the Labcorp Patient portal rather than requesting a fax.

What You Can Fax to Labcorp

  • Test order requisitions
  • Add-on and corrected test requests
  • Standing order authorizations
  • Supporting diagnosis and medical-necessity notes
  • Result-copy or records requests for the ordering provider
Tip: Make sure the ordering provider's fax on file with Labcorp is accurate, because results follow the number registered to that clinician's account rather than the sender of the order. Because lab data is protected health information, send through a HIPAA-eligible service like Send FAX Mail's Business plan ($79.99/month) and hold onto the delivery receipt. Note the patient's name, date of birth, and ordering provider on the requisition.

Faxing to Labcorp — FAQ

Completed results go to the fax number stored on the ordering provider's Labcorp account, established when the account is set up and adjustable through client services. When results don't reach your office, check that registered number before looking for a generic Labcorp fax.

A signed requisition normally travels with the specimen to the lab or patient service center, while fax is often used for add-ons, corrections, or standing-order paperwork. Ask the servicing Labcorp lab or client services how it prefers to receive order documents for your account.

A hospital records office faxes charts on request, whereas Labcorp's fax activity centers on requisitions going in and results going back to the ordering provider. The destination is set by the lab account and the servicing location, not by a general medical-records desk.

Patients usually retrieve results through the Labcorp Patient online portal or a formal records request rather than a fax. The faxed-result channel is designed to deliver to the ordering clinician, so patient copies go through a different process.
