Benzoylecgonine Metabolite

Hair sample drug testing is an excellent way to detect drugs or not a person used within 90 days. drug test hair sample is efficient in determining an individual's history of drug use compared to 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 the blood of a person who nurtures the development of hair follicles. A simple laboratory test can detect traces of these chemicals to a test result is positive or negative.

Hair Follicle Drug Test:

Hair drug testing is the method of detecting drugs in hair using enzyme immunoassay (EIA). EIA measures of drug molecules in hair, which were deposited in the hair follicle after the drug was used. The five classes of drugs mandated by the federal government for drug testing hair: cocaine (cocaine and benzoylecgonine), marijuana (THC), opiates (codeine, morphine and 6 - Monacteyl morphine), methamphetamine (Meth, amphetamine and Ecstasy) and phencyclidine (PCP).

Before the drug test hair follicle is actually started, the shell of the lock of hair is pulled to remove any external contaminants. Sensitivity levels for the drug test hair follicle are different for the drug tested. Sensitivity levels for the drug test hair follicle are measured in terms of grams per milliliter Pico (pg / ml). The cutoff level for marijuana metabolite class is 1 pg / ml. whereas for the opioid class is 500 pg / ml. The other three classes of cocaine metabolite, phencyclidine (PCP) and amphetamines / Methamphetamine MDMA (ecstasy) have a reasonable level to 300 pg / ml.

Benefits of Drug Test follicle:

An illegal drug addict can abstain from drugs for three days to two weeks before applying for a job. With traditional drug screening, there are good chances that applicants testing negative, then start using again once they are hired in. There's also the possibility to alter the sample. Companies that implement hair follicle drug testing may be relieved to know that this is not possible with hair testing. Abstaining or alter the sample can not beat hair tests.

drug testing programs often incorporate employee drug testing hair follicle in their plans because of the very precision of these tests. Similarly, drug testing hair follicle does not involve the embarrassing collection of samples such as urine or saliva testing. In most cases, a few strands of hair are all that is necessary to obtain accurate results.
