By design, the Lab Value annotator avoids ranges if possible:
// prefer non-range values, if any
> value = candidateList.stream()
> .filter( a -> !(a instanceof RangeAnnotation) )
> .orElse( candidateList.get( 0 ) );
The design is intended to cope with the widest possible variety of formats,
and avoid confusion.
If you know where the reference ranges are going to be in your data, I'd
suggest annotating those separately,
using the referenceRangeNarrative feature with LabReferenceRange values
rather than conflating them with labValue / LabMention.
Caveat: When I wrote this last year, the range annotator didn't seem to be
picking up on decimal points. So, below, the first two got
RangeAnnotations, and the second two didn't.
