Hi,
Panels have a specific name
Stan tells me that LOINC can code most/all standard panels.
And can have an associated result describing the panel as a whole.
Plus context data pertaining to the panel and all its items.
E.g. /Haematology panel: normal./
Both the /Panelresult/ and the results of the individual items can to
be queried.
there is a linguistic thing going on here where we use the word 'panel'
to mean two things:
* something like 'battery result', e.g. the set of analyte test
results for a complete blood test (maybe 10 things), plus the
overall test meta-data, interpretation and so on
* just a group of items, e.g. the 10 CBC items.
I'd like to see a better agreement on the real meaning of this word. Or
maybe it is just me who needs a better understanding.
Remarks:
- The individual /Itemresults/ are the result of a process and
therefor Observations (ENTRIES)
It has not been modelled like this, but scientifically it's a reasonable
view. It's a bit heavy in terms of information structures though. I'm
inclined to still allow grouping of analytes in a single Observation for
practical reasons - e.g. at least for groups of analytes that are
obtained by the same method, etc. But the more I learn about path lab
results, maybe it is worth revisiting this question.
- The /Panelresult/ is the result of an EVALUATION
I'm not sure I agree on this, unless you are talking about the a data
point like 'pathological interpretation' but I think this has to be
understood not as a Dx on the patient but a standard Dx that should be
inferred from the path value e.g. high Potassium => possible kidney
compromise. I have no expertise in this, so could be wrong, but from a
common sense point of view, I don't see how a lab can provide a Dx on
the actual patient without examining the patient history / EHR.
I don't think 'normal' should be understood as an evaluation on the
patient - it's just the lab saying: all the analytes are within normal
ranges for the patient type (adult male or whatever).
Interested to know if others disagree violently...!
