Laboratory specimens that are unlikely to cause disease and do not meet the criteria for category A or B substances are not subject to Division 6.2 regulations. Specimens for which the hazardous materials regulation (HMR) does not apply include human or animal samples (including, but not limited to, secreta, excreta, blood and its components, tissue and tissue fluids, and body parts) being transported for routine testing not related to the diagnosis of an infectious disease. This includes specimens that are being sent for:
- drug or alcohol testing
- cholesterol testing
- blood glucose level testing
- prostate specific antibody (PSA) testing
- testing to monitor kidney or liver function
- pregnancy testing
- tests for diagnosis of non-infectious diseases such as cancer biopsies
The US Department of Transportation (DOT) has no "Exempt Specimen" classification and there are no DOT guidelines for packaging non-regulated specimens.* According to the DOT, in the U.S., if a package is marked as "Exempt Human/Animal Specimen" the understanding is that it contains no infectious substance.
However, both IATA and the US Postal Service (USPS) have these requirements for packaging exempt specimens:
Type of packaging required | Triple packaging | Triple packaging |
Outer container | - One dimension must be a minimum of 100 mm X 100 mm (approximately 4 x 4 inches)
- Must be able to survive a drop test of 4 feet
| - One dimension must be a minimum of 100 mm X 100 mm (approximately 4 x 4 inches)
- Must be able to survive a drop test of 4 feet
|
Quantity limits: outer container | None | None |
Quantity limits: Primary receptacle | None | 500 mL |
Quantity limits: secondary packaging | None | 500 mL |
* Non-regulated specimens may become regulated because of preservatives, such as 10% formaldehyde (class 9) or 25% formaldehyde (class 8); or 25% ethanol (class 3).
