Specifically includes healthy tissue specimens used for HLA typing when shipped on dry ice by air via FedEx.

• A. Applies only to nonhuman samples
• B. Applies only to samples shipped by ground
• C. Applies to any tissue sample shipped on dry ice
• D. Specifically includes healthy tissue specimens used for HLA typing when shipped on dry ice by air via FedEx

Answer: (D)

The main idea here is that the regulations for shipping biological substances by air explicitly cover human tissue specimens, including those used for HLA typing, when they are shipped with dry ice. Even if the tissue is healthy and not infectious, it is still treated as a clinical specimen and must follow the packaging and labeling rules that apply to dry ice shipments and to clinical specimens (often Category B if applicable). Shipping this type of material by air with a carrier like FedEx falls squarely within that scope, which is why this option is the best match. The other statements miss the scope in key ways: they limit it to nonhuman samples, to ground shipments, or to any tissue shipped on dry ice without specifying the concrete scenario of healthy human tissue used for HLA typing transported by air.
