| name | Cytochrome B5 reductase [Presence] in Red Blood Cells | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Cytochrome b5 reductase | ||
| property | PrThr = Present or threshold: The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold. | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||

| 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. | ||
