Shipment of medical diagnostic specimens is also regulated by the FAA and individual overnight courier services. Please consult your courier for their specific packaging requirements and acceptable shipping options for medical specimens.

General packaging guidelines include wrapping glass tubes in absorbent padding, including at least one water-tight barrier in the packaging, and always mailing specimens in a sturdy box.  Your courier service may also require a special outer envelope identifying the package as a biological substance 

Each specimen should be accompanied by:

  1. A copy of our requisition form. (See the Forms page to download)
  2. Appropriate family history and/or medical information for the test being ordered (please see individual test pages for specific requirements)
  3. Payment information. Testing will not be initiated until financial responsibility is established.
