Resource Profile: Healthy Route Measurement

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.

Usages:

• Refer to this Profile: Healthy Route Reported Condition, Healthy Route Laboratory Report, Healthy Route Reported Medicine, Healthy Route Measurement and Healthy Route Investigation Request
• Examples for this Profile: Observation/ExampleCreatinine, Observation/ExampleEgfr, Observation/ExampleHba1c, Observation/ExampleHistoryDiabetes... Show 3 more, Observation/ExampleSmokingStatus, Observation/ExampleUacr and Observation/ExampleUrineDipstick
