Yes. Fluoxetine is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 50 ng/mL. Fluoxetine 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.
Fluoxetine is an SSRI antidepressant. The body converts it into norfluoxetine, an active metabolite that stays in the body for a long time.
Also known as or found in: Prozac.
Fluoxetine is prescribed for depression, obsessive-compulsive disorder, panic disorder, bulimia and some other conditions.
Fluoxetine 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 Fluoxetine 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 14 compounds in the antidepressants family on the 76-drug confirmation panel.
The laboratory's confirmation report lists an approximate detection window of 1-3 days for Fluoxetine. 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.
Fluoxetine 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.
Because norfluoxetine lingers, it can remain measurable for a considerable time after fluoxetine is stopped.
Commonly prescribed antidepressants and their metabolites. They are not part of standard drug screens and are identified when a clinician needs a full medication picture.

LabX reports Fluoxetine 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.
