Resource Profile: AU Base Diagnostic Result

This profile defines an observation structure to represent a diagnostic investigation result issued by a diagnostic service provider in an Australian context. This profile may be used to represent a specialist or other diagnostic (not imaging or pathology) observation including results of audiology studies, sleep studies or speech pathology. The observation may represent the result of a simple investigation or it may group the set of results of a multi-modality procedure or multi-test study / panel.

Usage:

• Refer to this Resource Profile: AU Base Diagnostic Report, AU Base Diagnostic Result, AU Base Diagnostic Imaging Report, AU Base Diagnostic Imaging Result... Show 2 more, AU Base Pathology Report and AU Base Pathology Result
