Existing Wording: DiagnosticOrder.item - The specific diagnostic investigations that are requested as part of this

request. Sometimes, there can only be one item per request, but in most

contexts, more than one investigation can be requested.

Comment:

Not clear what the item is versus the code. The code will include a name and coding system (No). What additional info does the item add, and how is it represented. Don't see a data type.

Oops now I see that is the mother object for the more specific that follow. Don't have to respond to my comment.
