About Drug Testing in Riverside
Drug testing analyzes a sample to identify recent or prior use of certain drugs.
Most drug tests screen for a panel of common substances, such as amphetamines, benzodiazepines, cannabinoids, cocaine, opioids, and phencyclidine. The exact panel depends on the purpose of the test and the instructions provided by the requesting party.
Screening is typically done by immunoassay, a method that flags samples that may contain a drug above a defined threshold. A presumptive positive screen is often followed by a more specific confirmatory method, such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry, to verify the result.
Results are reported as negative, positive, or, in some cases, inconclusive. A negative result generally means that no target substance was detected at or above the cutoff. A positive result indicates that a target substance or its metabolite was detected, and confirmatory testing may be required before a result is considered definitive.
