last change typeNAM  - change to Analyte/Component
change reasonRelease 2.67: COMPONENT: Updated "receptor" to "water channel" per current scientific nomenclature; Previous Releases: The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
