Hair drug testing costs much more than sweat, saliva or urine tests. However, the benefits often far outweigh the costs. Employers find hair follicle drug testing to be less invasive and it can often detect drugs as much as twice as far back as other testing methods. Hair follicle testing can also reveal if an employee has recently stopped using drugs in order to hide their usage. Another advantage is the fact that it’s usually harder to mask drugs in the system with this form of testing. The hair follicle drug test requires taking a small sample of the employee’s hair. An official within the company can often collect the hair on-site which is less embarrassing than the collection of urine. The sample is sent to the lab where it is first washed before being tested. This is done to minimize the chance of drug chemicals that may have originated from external sources affecting the test. Urine testing is still commonly used by employers to screen existing or prospective employees for drug use. However, many are beginning to turn to hair follicle drug testing. Although many people use different methods such as purchasing urine from a “clean” individual to beat a urine test, they are unable to beat the current masking procedures currently used in hair drug testing. Some products claim to be able to mask drugs in hair samples, but these are usually inaccurate or completely false claims. Hair follicle drug testing is a less invasive and more effective method than other choices. Article Source: http://www.articlewheel.com
