This structure refers to these other structures:

Slices

This structure defines the following Slices:

The element 1 is sliced based on the value of Observation.category

Other representations of profile: CSV, Excel, Schematron

Notes:

以下概述了此Profile所需的RESTful FHIR互動功能。有關TW Core IG支援的RESTful互動功能的完整清單，請參閱TW Core Server能力聲明。

必須支援以下查詢參數：
