Existing Wording: Observation.related - Related observations - either components, or previous observations, or

statements of derivation.

Comment:

More should be said about grouping and how these represent panels in the discussion of related observations. I didn't get the main usage for them until I read orders and all of the other content

This should be explained here, And the examples shown are not ideal unless one slips in the word panels to help explain them

Observation related needs more thought. Blood pressure systolic and diastolic have no more special relation ship than serum sodium and potassium and chloride . (which can generate the anion gap) Or the pressure in the R and L eye.

However except for general panel, there is hardly any need for these special relationships to be instantiated as structures because they can be constructed as reports based on knowledge about the variables that is independent of the specific patient or results. he because they are true generally and and be organized as desired at reporting time. via information in the master files. Having a field for their use will just encourage extra work.
