Order Drug TestingDrug testing is a laboratory analysis used to detect the presence of specific substances or their metabolites in a biological sample.

About Drug Testing in Brea
Drug testing refers to a set of analytical techniques that screen for and, when necessary, confirm 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, opioids, cannabinoids, cocaine, and benzodiazepines. A reactive screen is presumptive, not definitive, and is typically followed by a more specific method like gas or liquid chromatography coupled with mass spectrometry to confirm and quantify the finding.
The detection window varies by substance, dose, frequency of use, and the specimen tested. Urine generally offers the longest window for most drugs, while blood reflects very recent use, saliva captures recent exposure, and hair can indicate a much longer history. No single specimen is universally superior; each has distinct advantages and limitations.
Results are reported as negative, presumptive positive, or confirmed positive, often with the cutoff concentration applied. A confirmed positive indicates that a substance or metabolite was detected above the laboratory's threshold, but it does not by itself establish impairment, timing, or the route of exposure. Interpretation always requires clinical or contextual judgment.
