Order Drug TestingDrug testing is a laboratory analysis used to detect the presence of specific substances or their metabolites in a biological sample. It is a broad category that encompasses several specimen types and testing methods, each with its own detection windows and reporting conventions. Understanding what a drug test measures—and what it does not—helps put results into context.
About Drug Testing in Bothell
Drug testing refers to the laboratory screening and confirmation of drugs or drug metabolites in specimens such as urine, blood, oral fluid, or hair.
Most drug tests begin with an immunoassay screen, which produces a presumptive result based on a threshold concentration called a cutoff. A negative screen is generally reported as negative. A presumptive positive screen is typically followed by a more specific method, such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry, to confirm the identity and quantity of the substance.
Detection windows vary by substance, specimen, and pattern of use. Urine generally captures recent use over a period of days, while hair can reflect a longer historical window. Blood testing is often used when precise, current concentrations are needed. Oral fluid testing is valued for its ease of collection and its correlation with recent use.
Results are reported in a standardized manner, usually as negative, positive, or, in some contexts, inconclusive. Positive results are generally tied to a specific analyte and its concentration. Laboratories follow chain-of-custody procedures when specimens are collected for forensic, employment, or legal purposes, which helps ensure that the specimen is not compromised from collection through analysis.
