Benefits of Lab-based Urine Drug Testing

Urine drug testing detects recent drug use and is the only testing method approved for federally-mandated testing. Businesses rely on laboratory-based urine testing for its cost-effectiveness, capacity to screen for a variety of different illicit drugs and ability to withstand most legal challenges. Urine testing from Quest Diagnostics is an ideal solution for a wide variety of drug testing programs.

Drug testing aims to filter drug users from the workplace as well as to deter drug use on the job. Urine testing is the most common screening method and detects recent use, typically in the previous one to three days. Urine testing is suitable for all testing reasons – from pre-employment to random to post-accident – and can be performed for a wide range of illicit and prescription drugs. 

While a positive urine test does not necessarily mean that an individual was "under the influence" at the time of the test, it has become the standard for evidence of "current use" for the U.S. Department of Labor. Urine testing is also the only method allowed for federally mandated tests.

Specimen Validity Testing
While it is the most common drug testing method, urine testing is not foolproof. With our TestSure™ specimen validity testing, you can help ensure the integrity of the test by measuring pH, creatinine and specific gravity (when indicated) and testing for adulterants that may be added to the urine specimen. The adulterants detected include household chemicals (e.g. bleach), glutaraldehyde, nitrites, chromates and other oxidizing agents such as halogens. Quest Diagnostics is one of the few laboratories to offer oxidant identification for some of the most common oxidizing adulterants. All “invalid results” are automatically tested twice to ensure accuracy.

Demonstrated ROI
Drug abuse in the workplace puts employers at a risk for higher insurance costs, more on the job accidents, increased absenteeism and lower productivity. Urine testing, like all drug testing methodologies, helps to mitigate these risks by screening out applicants and employees who use drugs.
