Yes. Pseudoephedrine is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 50 ng/mL. Pseudoephedrine 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.
Pseudoephedrine is a decongestant with mild stimulant properties. It is structurally related to amphetamine-type compounds.
Also known as or found in: Sudafed.
Pseudoephedrine is used for nasal and sinus congestion and is sold behind the pharmacy counter under federal purchase limits.
Pseudoephedrine 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 Pseudoephedrine 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 8 compounds in the stimulants family on the 76-drug confirmation panel.
The laboratory's confirmation report lists an approximate detection window of 1-3 days for Pseudoephedrine. 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.

Laboratory confirmation identifies pseudoephedrine specifically, which helps distinguish an ordinary cold medicine from amphetamine-class drugs.
Prescription ADHD and weight-management stimulants, a common decongestant, and illicit stimulants including the cocaine metabolite benzoylecgonine and MDMA.

LabX reports Pseudoephedrine 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.
