last change typeMIN  - change to field other than name
change reasonThe scale has been changed from ACnc to reflect new model for ordinal terms; 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.
