MyHealtheVet PHR FHIR API, published by VA Digital Services. This guide is not an authorized publication; it is the continuous build for version 0.3.9-current built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/department-of-veterans-affairs/mhv-fhir-phr-mapping/ and changes regularly. See the Directory of published versions

A profile showing how HDR labTests.chemistryResults will be exposed using FHIR API to MyHealtheVet PHR.

One Observation holds one labTests.chemistryResults

  • This profile is based on US-Core Lab
    • category must have http://terminology.hl7.org/CodeSystem/observation-category#laboratory
  • .subject must be the patient from the DiagnosticReport
  • valueInterpretation -> .interpretation
  • testIdentifier -> .code – where LN is Loinc
  • referenceRange -> .referenceRange.text – dont try to break out further as there is little use of this value
  • labCommentEvents -> .note.text
  • value[x] either String or Quantity with units
  • observationValue -> .valueQuantity.value
  • observationUnits.unit -> .valueQuantity.unit
  • observationUnits.code -> .valueQuantity.code - likely need to adjust some
  • observationUnits.codingSystem -> .valueQuantity.system
  • performingOrganization -> .performer
  • labCommentEvents -> '.note`
  • effective[x] is same as the DiagnosticReport
  • issued is same as the DiagnosticReport
  • specimen = specimen
  • basedOn = ServiceRequest
  • ObservationStatus' -> [concept map translation](ConceptMap-VF-ChemistryResult-ObservationStatus.html) -> .status`
