Order Drug TestingA drug test is a laboratory analysis that detects the presence of specific substances or their metabolic byproducts in a biological sample. It is used in clinical, workplace, and legal contexts to document recent or ongoing exposure to drugs. The test does not diagnose addiction or impairment; it reports whether certain compounds are detectable at the time of collection.
About Drug Testing in Upland
Drug testing relies on immunoassay screening followed by confirmatory methods when needed.
Most drug tests begin with an immunoassay, a technique that uses antibodies to bind to drug molecules or their metabolites. A positive screening result is typically confirmed with a more specific method such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry, which identifies the exact compound present.
The detection window varies by substance, sample type, and frequency of use. Urine generally captures recent use over a few days, while hair can reflect a longer exposure period. Blood is useful for very recent use, and oral fluid offers a shorter detection window. Each matrix has distinct advantages and limitations that affect interpretation.
Results are reported as negative, positive, or inconclusive based on established cutoff concentrations. A positive result indicates that the substance or its metabolite was present at or above the cutoff, not the amount consumed or the time of use. Interpretation should account for prescribed medications, legitimate dietary sources, and collection timing.
