General Information

Test Ordering

  • How do I add on a test to a patient's laboratory test order after the specimen has been collected?

    If you have a LabCorp LinkTM login/password, you can submit your add-on test request electronically.  You may also call your local laboratory and add-on the test request.  After the verbal add-on order, you will receive a request for written authorization for the verbal order and LabCorp will provide a fax number to send this form back to the laboratory with signature and any other additional information that is required.

  • How do I receive updates regarding changes to Labcorp’s test offerings?

    Labcorp clients have access to our Test Change Notification system, which provides immediate access to changes that have occurred or are scheduled to occur in the Test Master database. Clients can view changes to all Directory of Service tests and to non-Directory of Service tests (based on account utilization). This eliminates the need to wait to receive a monthly change notification letter and to look at pages of changes that may not be relevant to your practice. Click here to sign up.

Specimen Collection

  • I need information about sample collection for a test being ordered for a patient.

    You may obtain specimen collection information from our online Test Menu by searching the test ordered and selecting Specimen in the left-hand navigation. LabCorp clients can access the AccuDraw tool for information about specimen collection. To access the tool, you must be a registered LabCorp LinkTMuser. For more information about LabCorp Link or to register, click here.
