Order Drug TestingDrug testing is a laboratory analysis designed to detect the presence of specific substances or their metabolites in a biological sample.

About Drug Testing in Vineyard
Drug testing is not a single test but a category of assays that screen for and, when needed, confirm the presence of drugs or drug metabolites.
Most drug tests begin with an immunoassay screen, which provides a rapid qualitative result. A reactive screen is typically not considered a final positive until it is confirmed by a more specific method such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry.
The sample matrix matters. Urine is the most common specimen because it allows a longer detection window for many substances. Blood is used when recent or active exposure is the question. Oral fluid is useful for detecting very recent use, while hair can reflect a longer history of exposure. Each matrix has its own detection characteristics.
Results are reported in a standardized way. A negative result indicates that the target substances were not detected at or above the assay's cutoff. A positive result indicates detection, and confirmation testing identifies the specific substance. Some reports also include quantitative values, which describe the concentration found in the sample.
