Order Drug TestingA drug screen is a laboratory analysis designed to detect the presence of specific substances or their metabolic byproducts in a biological sample.

About Drug Testing in Davis
Drug screening relies on analytical chemistry to identify substances that may be present in urine, blood, saliva, or hair.
Most drug screens begin with an immunoassay, a rapid technique that flags samples as negative or presumptive positive based on the binding of antibodies to target compounds. A presumptive positive result does not automatically confirm use; it indicates that further analysis is warranted to rule out cross-reactivity from unrelated substances.
Confirmatory testing, typically performed using gas chromatography-mass spectrometry or liquid chromatography-mass spectrometry, provides a more definitive identification by separating and quantifying individual compounds. This two-step approach is standard practice because it reduces the likelihood of false positives and produces results that can withstand professional or legal scrutiny.
The panel of substances tested varies by the purpose of the screen. Common panels include amphetamines, benzodiazepines, cannabinoids, cocaine metabolites, opioids, and phencyclidine, though expanded panels may cover additional prescription or illicit drugs. Results are generally reported as negative, positive, or inconclusive, with positive findings listed by substance class rather than by specific brand name.
