Muscle relaxants, sedatives and analgesics

Does a drug test detect Pregabalin?

Yes. Pregabalin is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 500 ng/mL. Pregabalin 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.

What is Pregabalin?

Pregabalin is a medicine related to gabapentin that acts on nerve signaling. It is a federally controlled (Schedule V) substance.

Also known as or found in: Lyrica.

Medical use

Pregabalin is prescribed for nerve pain from diabetes or shingles, fibromyalgia, and as an add-on treatment for some seizures.

How LabX tests for Pregabalin

Pregabalin 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 Pregabalin as detected when its concentration is at or above the cut-off of 500 ng/mL, within a reportable range of 500–50,000 ng/mL. It is one of 9 compounds in the muscle relaxants, sedatives and analgesics family on the 76-drug confirmation panel.

Detection window

The laboratory's confirmation report lists an approximate detection window of 1-4 days for Pregabalin. 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.

Screen versus confirmation

Pregabalin 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.

Worth knowing

Pregabalin is not part of standard drug screens and is identified by laboratory confirmation.

Common questions

Does a drug test detect Pregabalin?

Yes. Pregabalin is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 500 ng/mL. Pregabalin 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.

What is the laboratory cut-off for Pregabalin?

LabX reports Pregabalin as detected at or above 500 ng/mL, and the method's reportable range is 500–50,000 ng/mL. A result below the cut-off is reported as not detected; it does not prove none was present.

How long can Pregabalin be detected?

The laboratory lists an approximate window of 1-4 days, but it varies with dose, frequency of use, metabolism and hydration, and cannot be used to tell when something was taken.

Can a 12-panel drug screen detect Pregabalin?

Pregabalin 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.

Is Pregabalin a prescription medicine?

Pregabalin is prescribed for nerve pain from diabetes or shingles, fibromyalgia, and as an add-on treatment for some seizures.
