About Drug Testing in Fullerton
Drug testing refers to a set of analytical methods used to screen for and confirm the presence of drugs or drug metabolites in specimens such as urine, blood, saliva, or hair.
Most drug tests begin with an immunoassay screen, which reacts to drug classes like amphetamines, benzodiazepines, cannabinoids, cocaine, opioids, and phencyclidine. A positive screen is typically followed by a more specific confirmatory method, such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry, to identify and quantify the exact substance.
Results are reported as negative, positive, or, in some cases, inconclusive. A negative result generally means that the tested substances were not detected above the assay's cutoff concentration. A positive result indicates that a substance or metabolite was present at or above the cutoff, and confirmatory testing is used to rule out false positives from cross-reacting compounds.
Preparation depends on the specimen type and the laboratory's instructions. For urine tests, hydration status can affect sample adequacy, while some tests may require disclosure of prescription or over-the-counter medications that could influence results. Collection procedures are designed to maintain chain of custody and sample integrity when results may be used for legal or employment purposes.
