Order Drug TestingDrug testing analyzes a biological specimen for the presence of substances or their metabolites.

Results are reported as a laboratory finding, not as a clinical diagnosis, and interpretation belongs to the ordering provider.
About Drug Testing in St. Augustine
Drug testing is a laboratory method used to detect specific substances or their breakdown products in a specimen.
Most drug tests rely on immunoassay screening, which produces a preliminary result based on a chemical reaction between antibodies and the target compound or its metabolite. A screening result that requires confirmation is typically verified by a more specific method such as gas chromatography or liquid chromatography coupled with mass spectrometry. This two-tier approach reduces the chance that a structurally similar compound will be misidentified.
The detection window varies by substance, specimen type, and pattern of use. Substances cleared quickly may be detectable only for a short period, while those stored in fatty tissue or excreted slowly can remain detectable longer. Specimen type also matters: urine generally reflects recent use, while hair can provide a longer historical record and oral fluid reflects a shorter window. Because these variables differ, a negative result does not prove that no substance was ever used, and a positive result does not by itself establish impairment.
Laboratories follow chain-of-custody procedures when a result may be used for a non-clinical purpose, documenting each transfer of the specimen from collection to analysis. Reporting language is deliberately narrow: a result is described as negative, positive, or, in some cases, inconclusive, with a cutoff concentration applied to distinguish a true signal from background noise. The cutoff is a technical threshold, not a judgment about a person's behavior, and it is set by the laboratory or the requesting program.
