Background: This IG is unique because it describes a foundational set of profiles and associated FHIR Search API. Although this IG provide general guidances over select use cases, These use case are driven by USCDI requirements. For example see the SDOH Guidance for more information when exchanging Social Determinants of Health (SDOH) Service Requests. Nevertheless, the profiles are intended to be used by implementers and IG developers over a broad set of domains and use cases. To allow for this reuse the profiles set the  minimum  expectation for recording, searching, and fetching and thus contain few required elements and use broad or loosely bound terminologies. The expectation is that the implementer or implementation community will further constrain the US Profile for their particular use case, including primary clinical laboratory result reporting The examples used in US Core are intended to primarily to illustrate conformance to their corresponding profiles. Although we attempt to make them realistic, they are not representative of real world examples. Reasoning: We agree with the commenter that these examples do not meet the rigor of real world laboratory generated data. However we disagree that they need to. Their purpose is to illustrate conformant instances of US Core. We expect lab domain implementation communities to further constrain the US Core laboratory results profile for laboratory ordering and primary clinical laboratory result reporting and provide compliant examples. Proposed Changes: Add the following boilerplate to the introduction in the example page: These are example instances that show what data produced and consumed by systems conforming with this implementation guide might look like. Every effort has been made to ensure that the examples are correct and useful, but they are not a normative part of the specification nor are they fully representative of real world examples.   As well, we will add boilerplate to the examples to indicate that are not CLIA compliant.  We will reduce the number of examples and ensure that they are as clinically valid as possible. Suggestion: Feel free to submit a new use case for consideration as a candidate for inclusion in US Core after reviewing   http://build.fhir.org/ig/HL7/US-Core/future-of-US-core.html
