Order Drug TestingDrug testing encompasses laboratory methods that detect and sometimes quantify substances—prescribed medications, controlled drugs, or their metabolic byproducts—in a biological specimen. The test is used in clinical, workplace, and legal contexts, and the meaning of any result depends heavily on the specimen type, the detection window of the assay, and the cutoff thresholds applied by the performing laboratory.
About Drug Testing in Riverside
Drug testing is a category of analytical procedures rather than a single test, and results are reported in ways that reflect the specimen and the method used.
Specimens commonly submitted for drug testing include urine, blood, oral fluid, and hair. Each matrix carries different detection windows and different concentrations of parent drug or metabolite, so a result from one specimen type is not directly interchangeable with another.
Most screening assays are immunoassays that produce a presumptive positive or negative result relative to a stated cutoff concentration. A presumptive positive is typically confirmed by a more specific method such as gas chromatography–mass spectrometry or liquid chromatography–tandem mass spectrometry before a result is reported as definitive.
Reporting conventions vary by laboratory and by the purpose of the test. Some reports state only detected or not detected, while others provide numeric concentrations alongside the cutoff and, where applicable, the confirmation method. Interpretation should account for prescribed medications, legitimate metabolites, and the possibility of passive exposure.
