| change reason | Changed component name from "Phenothiazine" (singular) to "Phenothiazines" (pleural) to better reflect its long term intended meaning and current conventions. . Phenothiazine is a distinct chemical but has never been used in human medicine. (It was used for parasitic diseases in animals decades ago but not now). The word phenothiazine has always been used to mean the class of drugs that are derived from phenothiazine and laboratories that use phenothiazine and phenothiazines to mean the measure of any drug of phenothiazine class contained in the specimen.; The Property has been changed from ACnc to reflect the new model for ordinal terms where results are based on a cut-off value.; 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. | ||
