Yes. Amphetamine is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 50 ng/mL. The LabX 12-panel screen includes a Amphetamine line designed to pick up Amphetamine. A screen is presumptive; adding laboratory confirmation identifies Amphetamine specifically.
Amphetamine is a central nervous system stimulant. It is the active ingredient of several ADHD medicines and is also formed in the body from methamphetamine and from the prodrug lisdexamfetamine.
Also known as or found in: Adderall, Vyvanse.
Amphetamine medicines are prescribed for attention-deficit/hyperactivity disorder (ADHD) and narcolepsy.
Amphetamine 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 Amphetamine 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 2-4 days for Amphetamine. 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.

A laboratory result cannot tell a prescribed amphetamine from illicit use on its own; that distinction depends on prescription records reviewed by a licensed physician or Medical Review Officer.
Prescription ADHD and weight-management stimulants, a common decongestant, and illicit stimulants including the cocaine metabolite benzoylecgonine and MDMA.

The LabX 12-panel screen includes a Amphetamine line designed to pick up Amphetamine. A screen is presumptive; adding laboratory confirmation identifies Amphetamine specifically.
LabX reports Amphetamine 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 2-4 days, but it varies with dose, frequency of use, metabolism and hydration, and cannot be used to tell when something was taken.
