  title: Health Gorilla Lab Results Retrieval
  summary: Locate a patient, then pull their US Core laboratory DiagnosticReports, read one report, and retrieve the discrete result Observations.
  description: >-
    A results-retrieval flow against the Health Gorilla FHIR R4 clinical and lab
    network API. The patient is located by demographics, their laboratory
    DiagnosticReports are searched, a single report is read by id, and the
    discrete Observation results are retrieved for the patient. This mirrors the
    US Core DiagnosticReport and laboratory-result pattern over the /fhir/R4
    server base. Every step inlines its request so the flow is self-contained.
