Yes. Tapentadol is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 50 ng/mL. Tapentadol 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.
Tapentadol is a synthetic pain medicine that acts on opioid receptors and blocks the reuptake of norepinephrine. It is a federally controlled (Schedule II) substance.
Also known as or found in: Nucynta.
Tapentadol is prescribed for acute pain and, in an extended-release form, for certain chronic pain conditions including diabetic nerve pain.
Tapentadol 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 Tapentadol as detected when its concentration is at or above the cut-off of 50 ng/mL, within a reportable range of 50–5,000 ng/mL. It is one of 16 compounds in the opioids and their metabolites family on the 76-drug confirmation panel.
The laboratory's confirmation report lists an approximate detection window of 1-3 days for Tapentadol. Treat that as a rough guide only: how long any compound stays measurable varies with the amount taken, how often it is used, body composition, metabolism, kidney and liver function, and hydration. A laboratory result cannot be used to work out when a substance was taken.

Tapentadol is not picked up by standard opiate screens. Our LC-MS/MS confirmation measures both tapentadol and its metabolite N-desmethyltapentadol.
Prescription opioid pain medicines, heroin markers and the compounds the body makes from them. Measuring metabolites alongside parent drugs shows a drug was actually processed by the body.
Yes. Tapentadol is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 50 ng/mL. Tapentadol 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 Tapentadol as detected at or above 50 ng/mL, and the method's reportable range is 50–5,000 ng/mL. A result below the cut-off is reported as not detected; it does not prove none was present.
The laboratory lists an approximate window of 1-3 days, but it varies with dose, frequency of use, metabolism and hydration, and cannot be used to tell when something was taken.
