Healthy Route Implementation Guide
0.1.0 - ci-build

Healthy Route Implementation Guide, published by Savannah Informatics. This guide is not an authorized publication; it is the continuous build for version 0.1.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/savannahghi/healthy-route-ig/ and changes regularly. See the Directory of published versions

Resource Profile: Healthy Route Measurement

Official URL: https://fhir.savannahghi.org/ig/healthy-route/StructureDefinition/hr-observation Version: 0.1.0
Draft as of 2026-09-04 Computable Name: HRObservation

Any measurement taken from a participant during the screening visit.

Carries every measurement the study collects. What distinguishes one measurement from another is Observation.code, which is what a consumer filters on. Constraining the shape rather than the analyte means a laboratory adding a test does not require a change to this guide.
