Drug testing procedures have been implemented in various institutions to help detect drug abusers. Under general anesthesia, an individual is intravenously injected with pharmaceuticals in a controlled setting to examine the extent of the substance in the blood or the urine. A drug test is usually a specialized technical examination of an individual's blood, saliva, hair, urine, breath, or oral fluid/blood--to reveal the presence or absence of specific parent drug or its metabolites. The process has various options and can be employed for more specific tests. Depending on the needs of the dot physical exam las vegas, either blood or urine testing can be carried out. For blood tests, there are methods like alcohol dehydrogenase (ADH) and immunoassays that confirm the results obtained from the urine test. A false positive result from a urine test may be caused by the interaction of certain non-pharmacological factors such as temperature, environmental contaminants, and genetic differences among individuals. Because of the social and health problems arising from drug abuse, employers are now requiring drug testing of potential employees. The reasons for this procedure vary from company to company, but one common reason is the detection of drug abuse during the recruitment process. Most employers begin screening job applicants by conducting background investigations. They collect information about a person's education, work history, legal history, financial history, and character from references and the applicant's own statements. These data are then analyzed to detect drug use and addiction by the employer. A recent survey found that many employers were conducting drug testing conducted before the prospective employee was hired. An estimated 20% of those interviewed said they had conducted such drug tests. Overall, most of the employers who said they had conducted drug tests reported that they did not use the testing to prevent hiring the applicant, but rather to make sure that the person did not have a drug problem prior to employment. Some employers said they believed they were protecting the employee's rights by requiring drug testing but did not allow them to refuse.

Unfortunately, not all companies abide by this rule, so drug testing during the pre-screening phase can sometimes be inaccurate. Unfortunately, employers are not required to inform applicants of their rights during the screening or at the time of hire. Many employers simply take the applicant's word that they are not an alcohol user, do not have drug use problems, when in actuality, they do. This can lead to expensive lawsuits that the employee has to fight in court. Urinal drug testing is not the only way to screen people for illicit drugs. In the case of the accident, the police can perform a blood test, but this is not practical for many employers due to budgetary concerns. Therefore, urine drug testing has been widely used as the primary screening method, especially post-accident. If urine testing is performed, it is performed on the driver immediately following the accident, as most accidents occur at night or if work conditions are less likely to allow for a complete and accurate post-accident analysis.
