I'm not sure this is related with what you're discussing, but I have a question.
One of the results from Heptitis B virus surface Ab (concept_id = 3023421) in our institution is 'Positive, 85.34', which means positive for the Ab and value of titer is 85 (Definitely it is not wrong record).
In this case, we records both the value_as_number (85.34) and value_as_concept_id ('+').
Do we have standardized solution for this, too?
