I’m posting this here for public notice, though we’ll work on it here at Regenstrief. I’m not sure why, but some of the ValueSets (I noticed the Pos/Neg ones) have redundant LA codes listed in them.

For example:

[http://loinc.org/vs/LL2451-4](http://loinc.org/vs/LL2451-4)

[http://loinc.org/vs/LL360-9](http://loinc.org/vs/LL360-9)

Compare to the Details page listing:

[http://loinc.org/LL2451-4](http://loinc.org/LL2451-4)

[http://loinc.org/LL360-9](http://loinc.org/LL360-9)
