Yes. Naloxone is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 5 ng/mL. Naloxone is not one of the 12 lines on the LabX 12-panel screen. It is identified by adding laboratory confirmation, which tests for all 76 compounds on the panel.
Naloxone is an opioid antagonist: it blocks opioid receptors and can rapidly reverse the effects of an opioid overdose.
Also known as or found in: Narcan.
Naloxone is used as an emergency overdose-reversal medicine, available as a nasal spray (including without a prescription) and by injection. It is also combined with buprenorphine in some treatment medicines.
Naloxone is measured by liquid chromatography with tandem mass spectrometry (LC-MS/MS), which separates the compounds in a sample and identifies each one by its mass. That is different from a rapid screen, which reacts to a family of drugs and can occasionally react to a related substance. The laboratory reports Naloxone as detected when its concentration is at or above the cut-off of 5 ng/mL, within a reportable range of 5β500 ng/mL. It is one of 5 compounds in the opioid treatment and reversal family on the 76-drug confirmation panel.
The laboratory's confirmation report does not print a standard detection window for Naloxone. How long any compound stays measurable varies with the amount taken, how often it is used, metabolism and hydration, and a laboratory result cannot be used to work out when a substance was taken.
Naloxone is not one of the 12 lines on the LabX 12-panel screen. It is identified by adding laboratory confirmation, which tests for all 76 compounds on the panel.
Finding naloxone on a report can reflect a combination treatment product or emergency use. It does not by itself indicate opioid use.
Medicines used to treat opioid and alcohol use disorder or to reverse an overdose, with their metabolites, as monitored in treatment programs.

LabX reports Naloxone as detected at or above 5 ng/mL, and the method's reportable range is 5β500 ng/mL. A result below the cut-off is reported as not detected; it does not prove none was present.
The laboratory report does not print a standard window for Naloxone. Detection time varies with dose, frequency of use, metabolism and hydration.
