Extension: secondaryFinding

URL for this extension:

http://hl7.org/fhir/StructureDefinition/observation-secondaryFinding

Status: draft. Extension maintained by: Health Level Seven, Inc. - OO WG

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.

For more detail, please see: https://ghr.nlm.nih.gov/primer/testing/secondaryfindings.

Context of Use: Use on Element ID Observation
