Order Drug TestingDrug testing encompasses a range of laboratory methods used to detect the presence of specific substances or their metabolites in a biological sample. The scope of testing varies by panel, specimen type, and the reason the test was ordered. Results are typically reported as negative, positive, or inconclusive, with positive findings often subject to confirmation by a more specific technique.
About Drug Testing in Davis
Drug testing is a broad category of laboratory analysis rather than a single test. The substances screened and the specimen collected determine what the results can and cannot show.
Most drug tests begin with an immunoassay, a screening method that reacts to the presence of certain drug classes or metabolites. A negative result generally requires no further action. A positive or inconclusive screening result is commonly confirmed using a more specific method such as gas chromatography-mass spectrometry or liquid chromatography-mass spectrometry, which can identify the exact substance detected.
Specimen type affects both the detection window and the interpretation of results. Urine is the most common specimen and can detect recent use of many substances, though the window varies by drug and by individual factors. Other specimen types, including blood, oral fluid, and hair, are used in specific contexts and carry different detection periods and reporting considerations.
Results are reported in a standardized format that indicates whether the tested substances were detected. Reference ranges and cutoff concentrations are established by the laboratory and may follow federal or professional guidelines. A detected substance does not by itself indicate impairment, frequency of use, or the source of the substance, and results should be interpreted in the context of the ordering provider's clinical or administrative purpose.
