  title: Health Gorilla FHIR Lab Order
  summary: Confirm server capabilities, locate a patient, then place a laboratory order as a ServiceRequest grouped inside a RequestGroup.
  description: >-
    A FHIR R4 laboratory ordering flow against the Health Gorilla clinical and
    lab network API. The CapabilityStatement is fetched first to confirm
    supported resources, the patient is located by demographics, a ServiceRequest
    is created to describe the lab order, and a RequestGroup is submitted to bind
    the order before it is read back for confirmation. This mirrors the US Core
    ServiceRequest and order-placement pattern over the /fhir/R4 server base.
    Every step inlines its request so the flow is self-contained.
