Hair Follicle Drug Testing
Employee background checks and drug testing programs often incorporate hair follicle drug testing into their plans because of the sheer accuracy of these tests. Even though hair testing is more expensive that a urine drug test kit, for example, they can provide a level of accuracy that is nearly ten times that of other testing methods. Likewise, hair follicle drug testing does not involve the embarrassing collection of samples like that of urine or saliva drug tests. In most cases, a few strands of hair is all that is needed to obtain accurate results.
Hair sample drug testing is a great way to detect whether or not a person has used drugs in the past 90 days. Whether in an office format or in the home, hair drug testing serves the purpose of answering questions about an individual's drug use history.
Hair drug testing is actually quite simple and merely requires a sample of hair in order to be completed. Employers can request a sample from their employees. Once a hair sample has been collected, it is sealed in an envelope and sent to a participating laboratory for completion. Hair testing is fast and more accurate than other drug test forms.
For instance, hair sample drug testing can detect drug use for up to 90 days after use. The detection window is much larger in hair drug testing (compare it to few days for urine and saliva based drug testing) because trace amounts of drug chemicals become trapped inside each hair. A simple lab test can detect these trace chemicals making for either a positive or negative test result. Once the results are recorded, you are sent notification of the results. Some companies even provide a phone service where you call in, enter an account number and retrieve the results in that way.
Hair sample drug testing can detect all of the major types of drugs, including marijuana, opiates, methamphetamines, PCP, ecstasy, and cocaine. Hair follicle drug testing can detect the trace amounts of illicit substances trapped in the cortex of the hair for up to 90 days after use.
