Yes. Xylazine is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 10 ng/mL. Xylazine 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.
Xylazine is a veterinary sedative that is not approved for use in people. It has become a common adulterant in the illicit fentanyl supply, where it is sometimes called 'tranq'.
Also known as or found in: tranq.
Xylazine is approved only for veterinary use, mainly as a sedative for large animals.
Xylazine 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 Xylazine as detected when its concentration is at or above the cut-off of 10 ng/mL, within a reportable range of 10–1,000 ng/mL. It is one of 6 compounds in the dissociatives, adulterants and exposure markers family on the 76-drug confirmation panel.
The laboratory's confirmation report does not print a standard detection window for Xylazine. 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.
Xylazine 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.
Xylazine is not detected by standard drug screens and does not respond to naloxone the way opioids do. Laboratory confirmation identifies it, which can matter for a person's medical care.
Dissociative drugs, the street-supply adulterant xylazine, and markers of cannabis and alcohol exposure.
Yes. Xylazine is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 10 ng/mL. Xylazine 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.
LabX reports Xylazine as detected at or above 10 ng/mL, and the method's reportable range is 10–1,000 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 Xylazine. Detection time varies with dose, frequency of use, metabolism and hydration.
