About Drug Testing in Eureka
Drug testing screens for and, when necessary, confirms the presence of drugs or their breakdown products in a specimen.
Most drug tests begin with an immunoassay screen, which provides a rapid yes-or-no indication for a panel of substances. A negative screen is typically reported as negative, while a non-negative screen is often followed by a more specific confirmatory method such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry.
The panel of substances tested varies by the purpose of the test. Common panels include amphetamines, benzodiazepines, cannabinoids, cocaine metabolites, opioids, and phencyclidine, though the exact list depends on the requesting protocol. Detection windows differ by substance, frequency of use, and the type of specimen collected.
Results are reported as negative, positive, or, in some cases, inconclusive, with confirmatory testing providing the definitive finding. Cutoff concentrations are applied to distinguish true positives from background noise, and reporting language is standardized to avoid ambiguity.
