About Drug Testing in Walnut Creek
A drug screen is a qualitative or quantitative laboratory analysis designed to identify recent or ongoing exposure to certain compounds.
Most drug screens begin with an immunoassay, a technique that uses antibodies to bind to target substances or their breakdown products. A result is typically reported as negative, positive, or inconclusive, depending on the threshold set for each analyte.
The detection window varies by substance, specimen type, and frequency of use. Urine generally captures recent use over a period of days, while other specimen types may reflect a different window. A negative result does not necessarily rule out exposure outside the detectable timeframe.
Presumptive positive results are often confirmed by a more specific method such as gas chromatography-mass spectrometry. This two-step approach reduces the chance of a false positive from cross-reacting compounds and provides a defensible result for clinical or administrative purposes.
