About Drug Testing in Brentwood
Drug testing analyzes a sample to identify recent or ongoing use of certain drugs.
Most drug tests screen for a panel of common substances, such as amphetamines, opioids, cannabinoids, cocaine, and benzodiazepines. The specific panel depends on the purpose of the test and the instructions provided by the requesting party.
Samples can include urine, blood, saliva, or hair, each with different detection windows. Urine is the most frequently used sample because it is non-invasive and can detect drug metabolites for several days after use, though the exact window varies by substance and individual factors.
Results are generally reported as negative, positive, or inconclusive. A positive screening result is often followed by a confirmatory test using a more specific method, such as gas chromatography-mass spectrometry, to reduce the chance of false positives.
