  title: Canvas Medical Lab Order to Results
  summary: Place a laboratory order with a ServiceRequest, then retrieve the resulting DiagnosticReport and the discrete Observation results.
  description: >-
    A laboratory order-to-result flow against the Canvas FHIR R4 API. A
    ServiceRequest is created to order the lab, the resulting DiagnosticReport is
    searched for the patient, and the discrete laboratory Observations are
    retrieved. This mirrors the US Core DiagnosticReport / laboratory-result
    pattern. Every step inlines its request so the flow is self-contained.
