About Drug Testing in Riverside
Drug testing relies on analytical methods that identify and, in some cases, quantify substances or their breakdown products in the body.
Most drug tests are performed on urine, although blood, saliva, and hair can also be used depending on the purpose of the test and the detection window required. Immunoassay screening is commonly used as an initial method because it is rapid and broadly reactive; presumptive positive results are typically confirmed with a more specific technique such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry.
The panel of substances tested varies by context. Common targets include amphetamines, benzodiazepines, cannabinoids, cocaine, opioids, and phencyclidine, but panels can be customized to include other prescription or illicit drugs. Detection times differ by substance, sample type, dose, frequency of use, and individual metabolism, so a negative result does not always exclude use and a positive result does not by itself indicate impairment.
Results are reported as negative, positive, or, in some cases, inconclusive. A positive result generally reflects the presence of a drug or metabolite above a defined cutoff concentration, and confirmatory testing is used to reduce false positives from cross-reactivity. Interpretation should account for prescribed medications, legitimate dietary or environmental exposures, and the specific limits of the assay used.
