WHY DRUG TEST?

Southwest Labs offers drug testing for employers, providers, and other organizations. Reasons for drug test include: Pre-employment, suspicion, random testing, return to work, post-accident, and medication monitoring. Implementing a drug testing protocol in your business can reduce workplace outbreaks, reduce absenteeism, and improve compliance with state and federal regulations.

VALIDITY TESTING

Many drug users will attempt to evade detection by adulterating the specimen in order to produce false-negative results. Southwest Labs uses validity testing to detect urine adulteration by examining the following: Creatinine, General Oxidant, Specific Gravity, and pH.

TOXICOLOGY TESTING FAQ

Toxicology testing is used to screen for and confirm the presence of several drugs in a person’s sample, such as urine or oral fluid. Drug testing is used so that a person may receive appropriate medical treatment or be screened for or monitored for illegal drug use.

Drug testing for legal purposes primarily aims to detect illegal or banned drug use in a variety of situations. Sample collection procedures for this type of testing are strictly controlled and documented to maintain a legal “chain-of-custody.” The donor provides a sample that is closed and secured with a tamperproof seal in his or her presence. Specific chain-of-custody paperwork then accompanies the sample throughout the testing process. Each person who handles and/or tests the sample provides their signature and the reason for the sample transfer. This creates a permanent record of each step of the process.

Employment drug testing is a specific type of forensic testing (see above). It may be done prior to employment, on a random basis, following an accident, or if the employer has a reasonable suspicion that an employee is using illegal drugs. Employment drug testing is commonplace. It is required in some industries, such as those that involve the U.S. Department of Transportation, the military and federal employees, and is an accepted practice in many other industries.

While conventional drug testing is performed on competitive athletes, the primary focus is on doping, the use of drugs and/or supplements intended to promote muscle growth and/or to improve strength and endurance. On a local level, sports testing may be limited, but on a national and international level, it has become highly organized.

Drug screening in urine is the method of choice for monitoring adherence to prescription pain medications in patients treated for chronic pain. Urine drug screening provides tools for tracking patient compliance and exposing possible drug misuse and abuse. A health practitioner may periodically order drug testing for patients treated for chronic pain for two purposes: 1) ensuring compliance by patients who are using the prescribed pain medications, and 2) monitoring the use of non-prescribed or illegal substances. Elements of a urine drug screen may include specific gravity, temperature at the time of sample collection, pH, creatinine concentration, and confirmatory testing.

A positive initial drug screening means that the person tested has a substance in his or her body that falls into one of the drug classes and is above the established cutoff level. If secondary testing confirms a positive result, it means that the person has indeed taken this drug.
