PreNUDGE FHIR® IG for Data Provider / Data from Apps (R4) - Local Development build (v0.1.0) built by the FHIR (HL7® FHIR® Standard) Build Tools. See the Directory of published versions

## Resource Profile: AT PreNUDGE Observation Blood Glucose (only in mg/dL)

Official URL: https://fhir.hl7.at/prenudge/appdata/r4/StructureDefinition/at-prenudge-bloodglucose-observation | Version: 0.1.0
Draft as of 2026-06-18 | Responsible: The PreNUDGE Consortium | Computable Name: AtPrenudgeObservationBloodGlucose

This FHIR profile is defining the Blood Glucose Observation, similar to the Observation Social History - Alcohol Use from the IPS. The blood glucose option only allows values inbetween 0 and 999 mg/dL.

Usages:

- Examples for this Profile: Observation/bloodglucose-elevated-example, Observation/bloodglucose-low-example and Observation/bloodglucose-normal-example

You can also check for usages in the FHIR IG Statistics
