Extension secondaryFinding - Detailed Descriptions
Detailed Descriptions for the elements in the extension.
Extension
Element Id Extension
Definition
Secondary findings are genetic test results that provide information about variants in a gene unrelated to the primary purpose for the testing, most often discovered when Whole Exome Sequencing (WES) or Whole Genome Sequencing (WGS) is performed. This extension should be used to denote when a genetic finding is being shared as a secondary finding, and ideally refer to a corresponding guideline or policy statement.

Extension.url
Element Id Extension.url
Definition
Source of the definition for the extension code - a logical name or a URL.
Comments
The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
Fixed Value http://hl7.org/fhir/StructureDefinition/observation-secondaryFinding

Element Id Extension.value[x]
Definition
Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).
Terminology Binding Codes to denote a guideline or policy statement.when a genetic test result is being shared as a secondary finding.
The codes SHALL be taken from
Observation Category Codes; other codes may be used where these codes are not suitable
