Reference labs and specialized labs have sometimes complex instructions for interpretation of the results of some of their panels or tests. For example sophisticated tables of reference ranges including various criteria. They want to be able to provide this result interpretation guidance as a human-readable object, well formatted rather than as parsable structured data.

This calls for adding one more "summary" extension to the LabServiceDefinition profile of PlanDefinition.

Create this simple extension named ResultInterpretationSummary of type markdown.
