General Packing Guidelines
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.
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.

As of January 1, 2007, samples must be labeled: "Biological Substance, Category B". The terms "Clinical Specimen" and "Diagnostic Specimen" should no longer be used. See sample label that can be printed and affixed to your packages.
