Understanding what the test measures and how results are reported helps individuals interpret the findings accurately.
About Drug Testing in Carmichael
Drug screening relies on established laboratory methods to identify recent or ongoing substance use. The scope of testing is determined by the panel ordered, not by the test name alone.
Most drug screens use urine as the specimen, though other sample types may be appropriate depending on the panel and the detection window required. Common panels include amphetamines, benzodiazepines, cannabinoids, cocaine metabolites, opiates, and phencyclidine, among others. Each substance has a defined cutoff concentration, below which a result is reported as negative.
Laboratory analysis typically proceeds in two stages. An initial immunoassay screens the specimen and provides a preliminary result. Any presumptive positive is then confirmed using a more specific method, such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry, which identifies the exact compound present. This two-step approach reduces the chance of a false positive being reported.
Results are reported as negative, positive, or, in some cases, inconclusive. A positive result indicates that the substance or its metabolite was detected at or above the cutoff. Reporting may also include the concentration level and whether the finding is consistent with a prescribed medication, when that information is provided to the laboratory. Turnaround time is typically one to three business days, depending on the panel and any necessary confirmation testing.
