Part Description

LP35885-0   2-Ethylidene-1,5-Dimethyl-3,3-Diphenylpyrrolidine
EDDP (2-ethylidene-1,5-dimethyl1-3,3-diphenylpyrrolidine) is a primary metabolite of methadone, a synthetic opioid used for the treatment of opioid dependence. It is excreted in bile and urine along with other another methadone metabolite, EMPD. Levels of methadone itself are variable and depend on a patient's urine pH value, dose given, and metabolism. EDDP levels are less variable and can be detected 4 to 6 hours after methadone use, therefore, EDDP is preferentially used to check for methadone exposure. Source: Regenstrief Institute

Change Reason
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.
Order vs. Observation
Both
