Hair sample drug testing is a great way to detect whether or not a person has used drugs in the past 90 days. Hair sample drug test is efficient in determining an individualâ??s drug use history when compared with other drug tests because trace amounts of drug chemicals become trapped inside cortex of each hair. The presence of drugs in hair is based on a simple principle. Drugs that are ingested circulate in a person’s bloodstream that nourishes developing hair follicles. A simple lab test can detect these trace chemicals making for either a positive or negative test result.Hair Follicle Drug Test:
Hair drug screen is the method for detecting drugs in hair using enzyme-immunoassay (EIA). EIA measures the drug molecules in the hair, which were deposited into the hair follicle after the drug was used. The five drug classes mandated by the Federal Government for hair drug testing are: Cocaine (Cocaine & Benzoylecgonine), Marijuana (THC), Opiates (Codeine, Morphine & 6- Monacteyl Morphine), Methamphetamine (Meth, Amphetamine & Ecstasy) and Phencyclidine (PCP).
Before the hair follicle drug test is actually started, the shell of the hair strands is stripped away to eliminate any external contaminants. The sensitivity levels for hair follicle drug test are different for the drug tested. The sensitivity levels for the hair follicle drug test are measured in terms of Pico grams per Milliliter (pg/ml). The cutoff level for Marijuana metabolite class is 1 pg/ml. where as for Opiates class it is 500 pg/ml. The other three classes Cocaine metabolite, Phencyclidine (PCP) and Amphetamines/Methamphetamine MDMA (Ecstasy) have sensible levels at 300 pg/ml.Advantages of Hair Follicle Drug Test:
An illegal drugs substance abuser may abstain from using drugs for 3 days to 2 weeks prior to applying for a job. With traditional drug testing, there is a good chance that the applicants will test negative and then start using again once they are hired in. There is also the chance of adulterating the specimen. Companies that implement hair follicular drug testing can be relieved to know that this is not possible with hair testing. Abstaining or adulterating the specimen cannot beat hair tests.
Employee drug testing programs often incorporate hair follicle drug testing into their plans because of the sheer accuracy of these tests. 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 are all that is needed to obtain accurate results.

A well planned employee drug testing policy is an important matter of employee screening and can save the employers several thousand dollars each year. For this reason the employer must realize and understand that a successful employee drug testing program must be convenient and easy-to-use. Internet is the best place to search for the closest collection sites available. There are thousands of organizations that varies from small business to globally successful business that consider pre-employment drug test of the employees are useful while others may consider drug testing, credit checks, reference checks, and other pre-employment checks to be Gestapo tactics. Whatever view people hold for them yet they are legal. There are several organizations worldwide that provide exceptional service of drug testing. The organization that provides accurate, compliant and timely information to make informed decision and mitigate risks in critical areas such as employment, vendor selection, identity theft prevention and assistance, investment placement, and institutional admissions are considered excellent. While there are some services that adds some more addition to their services like preparing report to reveal the past criminal history, untruthful resumes and falsified employment applications that makes the employer weed out the candidates with such reports and select the best for their company thus keeping their working environment healthy.The existence of drugs in your system is directly under the influence of drug half-life, intensity, intensity of the usage, method of usage, length of usage, tolerance, fluid intake, body size, body fat, metabolism and the specific range which the drug testing lab uses to signify a “positive” for drug use so it is very difficult to say how long drugs will remain in your system. There is a table that mentions the amount of time a drug can be detected by most standard drug test but you should know that those detection times for instance – Marijuana (7–30 days), Opiates (1-4 days), Alcohol (6–24 hours) and Steroids (14–30 days) etc, does not mean that the drug is fully expelled from your body within that amount of time but that it has dissipated enough that it can no longer be accurately detected or at least it is not high enough to register a “positive” on a drug test. It is also true that most of the drugs are considered toxin by our body which take time to eliminate, so they are often stored in fat cells rather than allowing excess toxins to potentially affect vital organs thus making them even difficult to release or detoxify from the body. You should understand the fact that if there is a drug out there then there is a drug test for it but basically there are “Five-Screen” (or “NIDA-5” or “SAMHSA-5”) which is testing for five types of drugs used by most corporate drug testing programs and they are Cannabinoids (Marijuana, Hashish), Cocaine (Cocaine, Crack, Benzoylecognine, Opiates (Heroin, Opium, Codeine, Morphine), Amphetamines (Amphetamines, Methamphetamines, Speed) and Phencyclidine (PCP, Angel Dust). So it is important for the candidate appearing for a pre-employment drug test to make a list of medications you are presently taking or have taken in the last thirty days and even over-the-counter medications so that you are on the safe side.
