Multiplex Assay tests that serve as a single test to diagnose infection caused by multiple viruses (e.g. CDC Flu SC2 Multiplex Assay for SARS-CoV-2, influenza A, and/or influenza B viruses), use multiple Observation.component elements to record each type of test.

I am not sure this statement is correct - I think individual results for different viruses should be sent as separate observations grouped by observation.hasMember for the ordered panel, becasue each interpretation is different (detected for Flu A would be abnormal, but not detected for SARS-COV-2, Flu B would be normal). Component should be used when interpretation is the same across all components, though I see, that component has its own interpretation now  - maybe bring this one to an OO Lab call, or the main call for discussion
