A patient's urine specimen sent to participate in a clinical trial that is unlikely to contain a pathogen is classified as which type of shipment?

• A. Exempt patient specimen
• B. Not regulated
• C. Category A Infectious substance
• D. Category B Infectious substance

Answer: (A)

The main idea is how transport rules treat patient specimens that pose little to no infectious risk. When a urine sample from a patient, such as one sent for a clinical trial, is unlikely to contain viable pathogens, it lines up with an exempt designation for patient specimens. That means it isn’t handled as an infectious substance under the main Category A/B rules, but it isn’t tossed out of regulatory oversight entirely either—the exempt category exists within the regulatory framework to simplify handling while still ensuring safe transport. So this specimen is categorized as an exempt patient specimen because the risk is not enough to require infectious-substance packaging and labeling. Category A or Category B would apply only if there were a suspected or known infectious agent present. The option “not regulated” would imply no regulatory requirements at all, which isn’t the intended distinction here—the exempt designation is specifically for specimens that are exempt from the full infectious-substance rules.
