Yes. Baclofen is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 200 ng/mL. Baclofen 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.
Baclofen is a muscle relaxant that acts on GABA-B receptors in the nervous system.
Also known as or found in: Lioresal.
Baclofen is prescribed for muscle spasticity from conditions such as multiple sclerosis and spinal cord injury.
Baclofen 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 Baclofen as detected when its concentration is at or above the cut-off of 200 ng/mL, within a reportable range of 200–10,000 ng/mL. It is one of 9 compounds in the muscle relaxants, sedatives and analgesics family on the 76-drug confirmation panel.
The laboratory's confirmation report does not print a standard detection window for Baclofen. 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.

Baclofen is not part of standard drug screens; it is identified by laboratory confirmation.
Muscle relaxants, barbiturates, nerve-pain medicines and acetaminophen, several of which are monitored in pain management and treatment programs.
Yes. Baclofen is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 200 ng/mL. Baclofen 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 Baclofen as detected at or above 200 ng/mL, and the method's reportable range is 200–10,000 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 Baclofen. Detection time varies with dose, frequency of use, metabolism and hydration.
