About Drug Testing in Berkeley
A drug profile, also known as drug testing, screens for and sometimes confirms the presence of specific substances or their breakdown products in the body.
Most drug tests use urine, but blood, saliva, hair, or sweat can also be analyzed. Screening tests are immunoassays that provide a rapid yes/no result, while confirmatory tests such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) are used to verify positive screens with high specificity and accuracy.
The substances commonly included in a drug profile vary by panel. A standard 5-panel typically covers amphetamines, cocaine, marijuana, opiates, and phencyclidine (PCP). Expanded panels may add benzodiazepines, barbiturates, methadone, methamphetamine, MDMA, oxycodone, and others. Each drug has a detection window that depends on the substance, dose, frequency of use, and individual metabolism.
Results are reported as negative, positive, or inconclusive. A negative result means no drug or metabolite was detected above the assay's cutoff concentration. A positive result indicates detection at or above the cutoff and is usually followed by a confirmatory test. Inconclusive results may require a new sample. Interpretation should always consider the testing method, cutoff levels, and possible cross-reactivity.
