Every compound in the LabX 76-drug LC-MS/MS confirmation panel, explained in plain language β what it is, how it is used in medicine, the laboratory cut-off, the approximate detection window and whether a standard 12-panel screen picks it up.
Pick a compound below or start with the full confirmation panel list. Compounds are grouped into the same nine families the laboratory uses. Many entries are metabolites β compounds the body makes from a drug β which laboratories measure because they last longer or show the drug was actually processed by the body. For definitions, see the glossary; for quick answers, see LabX answers.
Prescription opioid pain medicines, heroin markers and the compounds the body makes from them. Measuring metabolites alongside parent drugs shows a drug was actually processed by the body.
Fentanyl and its metabolite, plus the main alkaloids in kratom. These are not reliably found by general opiate screens, which is why confirmation measures them directly.
Medicines used to treat opioid and alcohol use disorder or to reverse an overdose, with their metabolites, as monitored in treatment programs.
Prescription ADHD and weight-management stimulants, a common decongestant, and illicit stimulants including the cocaine metabolite benzoylecgonine and MDMA.
Prescription sedatives and sleep medicines and their metabolites. Standard screens detect individual benzodiazepines unevenly, so confirmation identifies each one.
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.
Medicines prescribed for psychiatric conditions and anxiety, identified by confirmation when a medication list needs to be checked.
Muscle relaxants, barbiturates, nerve-pain medicines and acetaminophen, several of which are monitored in pain management and treatment programs.
Dissociative drugs, the street-supply adulterant xylazine, and markers of cannabis and alcohol exposure.
One page for each of the 76 compounds in the LabX LC-MS/MS confirmation panel, explaining what the compound is, its general medical use, the laboratory cut-off, the approximate detection window and whether the 12-panel screen covers it.
Each cut-off is the lower limit printed on the laboratory's own urine confirmation report. A compound is reported as detected at or above that concentration.
No. Windows are approximate and vary with dose, frequency, metabolism and hydration. A laboratory result shows whether a compound was present at collection, not when it was taken.
LabX offers a 12-panel drug test on urine or fingerstick blood, with optional laboratory confirmation of all 76 compounds.
