  1. Procedures

Service Request

Overview#

The ServiceRequest resource records requests for procedures, diagnostic tests, referrals, or other services to be planned or performed for a patient. These may result in a Procedure or DiagnosticReport, and can reference Observations, findings, or clinical justifications.
This resource is used for:
Referrals (e.g., specialist, SDOH support)
Test orders (e.g., ECG, lab tests)
Service requests by category (e.g., cardiology)
It conforms to the US Core ServiceRequest Profile and supports USCDI v2. The server returns results in FHIR R4 JSON format.
