Why 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 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.
What sets Quest Diagnostics apart for lab-based urine drug testing?
We offer reliable employee drug screening, an extensive national collection site network and personal service and support. Every Quest Diagnostics drug testing laboratory participates in rigorous lab proficiency testing to maintain the highest levels of Six Sigma quality. We have established a reputation as a national leader in workplace drug testing and test millions of urine drug testing every year.
Why is urine testing the most frequently used method for drug testing?
Businesses drug test their applicants and employees to minimize their exposure to the risks of workforce drug use. While all drug test specimen types – urine, oral fluid and hair – have their advantages, urine drug testing is by far the most flexible and customizable. With hundreds of different combinations of detectable drugs, order codes and cutoff levels, there’s a urine test panel for almost any testing reason.
What is the detection window for a lab-based, urine drug test?
Urine drug testing detects recent drug use in the previous 24 to 72 hours.
What drugs are detected with a urine test?
Quest Diagnostics tests for the following drugs: amphetamines, barbiturates, benzodiazepines, cocaine, marijuana, MDMA (Ecstasy) and its metabolite, methadone, opiates, oxycodone, phencyclidine (PCP) and propoxyphene, synthetic cannabinoids (“K2/Spice”) and synthetic stimulants (“Bath Salts”). Additionally, we offer specialized panels such as Medical Professional Panels for a broad range of prescription drugs more accessible in the healthcare industry and a steroids panel to detect performance-enhancing drugs and anabolic steroid use.
Can a urine drug test be beaten or adulterated?
While it is the most common drug testing method, urine testing is not foolproof. With our TestSure™ specimen validity testing, we 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 most common adulterants screened include oxidizing agents – such as, nitrites, chromates and halogens (e.g., bleach and iodine). 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. We also offer oxidizing adulterant identification if requested by the customer or Medical Review Officer.
