What is the screening of drugs for hair?

Many employers are carried out by medication as part of their hiring processes. There are several types of tests that can detect drugs in the human system, and screening hair medicines is one of the most expensive and thorough tests. Hair drug screening uses a small human hair pattern to test follicles for any traces of current or previous drug use. Employers perform these tests because they believe that drug addicts are exposing the risk of accidents, theft and attendance issues.

The process of screening hair medicines usually occurs in a drug screening device. Approximately 40 to 50 strands of hair from the scalp is cut and then tested. If a person has a head, other types of body hair, such as hair armpit or hair hair, can be used. Most test devices use antibodies of the enzyme (EIA) to detect illegal substances in hair follicles.

Average human hair grows 0.5 inches (1.27 cm) per month and most test centers only test at 1.5 inches (3.81 cm). This shows that most hair screening tests look only to use drugs during the previous 90 days. The most common types of illegal drugs tested in this type of screening are marijuana, amphetamines, cocaine, opiates and phencyklidin.

Companies and businesses have high -safety protocols such as banks and coercive agencies usually use hair drug screening rather than other methods. In some cases, if a potential employee challenges the unsuccessful urine test, he will have to prove that he will prove the absence of the illlegal substance. Hair tests are usually more expensive than other types of drug screenings such as those that test urine, sweat or saliva.

There are many misconceptions and myths about screening tests on hair. Hair coloring techniques such as whitening or dyeing does not affect the resultKy testing, because the color covers only outer hair follicles. Shampoos, conditioners, gels and sprays also do not affect the test. Some people believe to be around another illegal drug smoke, including crack cocaine or marijuana, can cause the person to fail. This is also not accurate because the test focuses on hair metabolites that produce the body after drug consumption.
