| Exempt Substances 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 | View Page |
| Definitions Before further discussion of Category A and Category B, it is important to define two additional terms that are used in the classification process. CultureAn infectious substance containing a pathogen that is intentionally propagated, for example a bacterium grown on bacteriological medium as seen in the image below. Culture does not include a human or animal patient specimen.Patient specimenHuman or animal materials collected directly from humans or animals and transported for research, diagnosis, investigational acitivities, or disease treatment or prevention. Patient specimen includes excreta, secreta, blood and its components, tissue and tissue swabs, body parts, and specimens in transport media (e.g., transwabs, culture media, and blood culture bottles).* *It is important to note that this means specimens that have been collected into these transport media, but have not yet been incubated and are not actively growing in the media. | View Page |
