Order Drug TestingDrug testing is a laboratory analysis that detects the presence of specific substances or their metabolic byproducts in a biological sample. It is used in a variety of settings, from clinical care to workplace safety, and the interpretation of results depends heavily on the sample type, the substances screened, and the testing method employed.
About Drug Testing in Newark
Drug testing measures recent or past exposure to certain drugs by identifying parent compounds or their metabolites in a specimen.
Most drug tests begin with an immunoassay screen, which provides a rapid qualitative result. A reactive or presumptive positive screen is typically confirmed using a more specific method such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry.
The detection window varies by substance, sample type, and individual factors including metabolism, frequency of use, and dose. Urine generally offers the longest detection period for many drugs, while blood is useful for recent exposure and saliva can reflect very recent use.
Results are reported as negative, presumptive positive, or confirmed positive, often with the specific analyte and its concentration. A confirmed positive result indicates that the substance or its metabolite was present at or above the laboratory's cutoff, but it does not by itself establish impairment or the timing of use.
