Yes. Quetiapine is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 20 ng/mL. Quetiapine 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.
Quetiapine is an atypical antipsychotic medicine with sedating effects.
Also known as or found in: Seroquel.
Quetiapine is prescribed for schizophrenia, bipolar disorder and as an add-on treatment for depression.
Quetiapine 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 Quetiapine as detected when its concentration is at or above the cut-off of 20 ng/mL, within a reportable range of 20–2,000 ng/mL. It is one of 6 compounds in the antipsychotics and mood family on the 76-drug confirmation panel.
The laboratory's confirmation report does not print a standard detection window for Quetiapine. 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.
Quetiapine 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.
Quetiapine has been reported to cross-react with some immunoassay screens. LC-MS/MS confirmation identifies quetiapine itself.
Medicines prescribed for psychiatric conditions and anxiety, identified by confirmation when a medication list needs to be checked.
Yes. Quetiapine is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 20 ng/mL. Quetiapine 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 Quetiapine as detected at or above 20 ng/mL, and the method's reportable range is 20–2,000 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 Quetiapine. Detection time varies with dose, frequency of use, metabolism and hydration.
Quetiapine 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.
