About Drug Testing in Alton
Drug testing screens for and, when necessary, confirms the presence of drugs or their breakdown products in the body.
Most drug tests begin with an immunoassay screen that reacts to drug classes such as amphetamines, benzodiazepines, cannabinoids, cocaine metabolites, opioids, and phencyclidine. A screen result is preliminary, and any non-negative finding is typically sent for a more specific confirmatory method, most often gas chromatography–mass spectrometry or liquid chromatography–tandem mass spectrometry.
The detection window depends on the substance, the dose, the frequency of use, and the individual's metabolism. Urine is the most common specimen because it offers a relatively long detection period, while blood reflects recent use, saliva is useful for short-term detection, and hair can indicate a longer history of exposure. Each specimen type carries its own collection requirements and limitations.
Results are reported as negative, positive, or, in some panels, inconclusive. A positive result identifies the substance or metabolite above the assay's cutoff, and a confirmatory test is required before a finding is considered definitive. Prescription medications, foods, and some over-the-counter products can produce unexpected results, so a complete medication history is an important part of interpretation.
