Order Drug TestingDrug testing is a laboratory analysis used to detect the presence of specific substances or their metabolic byproducts in a biological sample. It is a broad category rather than a single assay, and the exact compounds screened for depend on the panel requested and the reason the test is being performed. Results are typically reported as negative or positive for each substance class, with confirmatory testing available when a screening result requires verification.
About Drug Testing in Lawrence
Drug testing encompasses a range of laboratory methods designed to identify recent or ongoing exposure to certain drugs and medications.
Most drug tests begin with an immunoassay, a screening technique that uses antibodies to detect drug classes such as amphetamines, benzodiazepines, cannabinoids, cocaine metabolites, opioids, and others. A screening result is considered presumptive, meaning it indicates the likely presence of a substance but does not by itself confirm it. When a screening result is positive, a more specific method such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry is often used to confirm the finding and identify the exact compound.
The specimen type influences what a drug test can reveal. Urine is the most common sample because it allows detection over a relatively long window and is easy to collect. Blood testing reflects substances circulating at the time of collection, giving a shorter detection window. Saliva and hair testing are also used in certain settings, each with its own detection characteristics and limitations. The choice of specimen is usually determined by the purpose of the test and the instructions provided by the laboratory.
Results are reported per analyte or drug class, generally as negative, positive, or inconclusive. A negative result means the substance was not detected above the assay's cutoff concentration. A positive result means it was detected at or above that threshold. Cutoff values and reporting formats vary between laboratories and panels, so results should always be interpreted in the context of the specific test performed and any relevant clinical or administrative information.
