Change Reason
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.; Updated Component from "NADH methemoglobin reductase" to "Cytochrome b5 reductase" per the recommended scientific nomenclature [https://enzyme.expasy.org/EC/1.6.2.2] and to align across LOINC terms.
