Order Drug TestingDrug Testing detects and, in some cases, quantifies the presence of specific substances or their metabolic byproducts in a biological specimen. It is used in clinical, workplace, and forensic settings, and the meaning of a result depends heavily on the specimen type, the panel ordered, and the detection window of each analyte.
About Drug Testing in Pasadena
Drug testing is a laboratory method for identifying recent or ongoing exposure to selected substances.
Most drug tests begin with an immunoassay screen that produces a presumptive positive or negative result based on a cutoff concentration. A presumptive positive is not a final diagnosis; it is typically confirmed by a more specific method such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry, which identifies the substance and can measure its concentration.
The specimen determines what can be detected and for how long. Urine is the most common specimen and generally reflects use within the preceding days, though detection windows vary by substance and pattern of use. Blood reflects very recent exposure, oral fluid covers a shorter recent window, and hair can indicate a longer historical pattern. Each matrix has its own collection procedure and its own set of analytes that can be reliably measured.
Results are reported as negative, presumptive positive, or confirmed positive, often with the analyte name and, when quantified, a concentration and the cutoff applied. Interpretation must account for legitimate prescription medications, poppy seed ingestion, and other sources of cross-reactivity that can produce an unexpected screen result. A qualified laboratory or clinician should be consulted for any result that requires clinical or legal interpretation.
