Laboratory Results Reporting

Overview

Laboratory Results are represented as an FHIR Diagnostic Report object. A diagnostic report is the set of information that is typically provided by a diagnostic service when investigations are complete. The information includes a mix of atomic results, text reports, images, and codes.

Each DiagnosticReport has next elements:

• a status
• a category code of ‘LAB’
• a code (preferably a LOINC code) which tells you what is being measured
• a patient
• a time indicating when the measurement was taken
• a time indicating when the measurement was reported

Each DiagnosticReport supports next elements:

• who issues the report
• a result

Profile specific implementation guidance:

• Additional codes that translate or map to the DiagnosticReport codes or category codes are allowed. For example:
  • providing both a local system codes and a LOINC code that it map to
  • providing a more specific category codes to the “LAB” category code, such as “CH” (chemistry), in an additional coding element.
• Results that are free text or report form are represented using the ‘presentedForm’ element in DiagnosticReport.

This resource conforms to USCDI V1 profile for DiagnosticReport - refer to StructureDefinition US Core DiagnosticReport Lab. DiagnosticReport response will be provided in JSON (refers to Capability Statement) format as per FHIR standard R4 version.
