Order Drug TestingDrug testing is a laboratory method used to detect the presence of specific substances or their metabolites in a biological sample. It serves clinical, workplace, and legal purposes, and the meaning of any result depends heavily on the sample type, the panel ordered, and the detection window of each substance.
About Drug Testing in Sterling
Drug testing is not a single test but a category of assays that screen for and, when needed, confirm the presence of drugs or drug metabolites.
Most drug tests begin with an immunoassay screen, which reacts to a class of compounds such as opiates, amphetamines, or cannabinoids. A screen result is preliminary: it indicates that a substance may be present, but it can also react to unrelated compounds with a similar structure.
When a screen is positive or otherwise requires clarification, a confirmatory method such as gas chromatography–mass spectrometry or liquid chromatography–tandem mass spectrometry is used. These techniques separate and identify specific molecules, which is why confirmatory results are considered more definitive than screening results.
Detection depends on the sample and the substance. Urine is the most common sample and typically reflects recent use, while blood, oral fluid, and hair each have different windows of detection. Results are generally reported as negative, positive, or, in some contexts, as a numerical concentration with a cutoff threshold.
