Urine Drug Test

Hundreds of thousands of urine drug tests are conducted every year because drug use is immediately detectable in a person’s urine. A urine drug test is able to determine a single substance or multiple substances.  Today, the emergence of the hair follicle test for employment is slowly becoming more popular in order to detect drug use. However, urine drug test continues to become the most commonly used test for pre-employment, post accident and reasonable suspicion test because it is inexpensive and non intrusive.

Urine Drug Screening

For how long drugs remain present in a person’s system depends on a number of factors. Some of these factors include a person’s metabolic rate, the amount of drugs consumed and the volume of fluids that have been excreted after drug use. A number of urine drug tests exist today and each one is designed to test for a different combination of substances. The standard test screens for the most predominant street drugs, including cocaine, marijuana, amphetamine, PCP, and opiates.

Before results are released, all findings are reviewed and verified by a trained medical review officer. This period allows time for individuals taking legally prescribed medicine to provide the necessary medication documentation before the final report is prepared. Results of a urine test, specifically results of a negative urine test are generally made available within 48 hours. Non-negative test can take up to three business days.

  • detect drug use 5 days or more after consumption since detectable drug compounds have passed through the body by then.
