What is the hair test?

Hair test for hair detection is a method of drug detection that is more reliable and better able to detect historical use of drugs than urine, saliva and blood samples. Indeed, drug tests that sample body fluids are only able to detect drugs that still persist in the system. However, hair follicles tend to hold traces of drugs for a long time, depending on the length of the sample. This makes it possible to detect a medical history of drug use, even if drugs are not present in the system. Another advantage is that the test is not limited to hair from the scalp; It can detect drugs in any follicle on the body. Hair hair tests are able to detect a wide range of medicines, including cocaine, opiates and narcotics.

The

hair test works so well because of the traces of drugs that blood speech in hair follicles. As hair grows, traces of drugs remain in the preliminary state. The only way to ensure ABY has removed the trace of the drug from the strand of the hair, it is completely removed by the strand itself. The shortest follicle is able to measure a period of about 90 days, which means that a person could stop taking drugs three months before the test and still return positive for a history of drug use. The longer the hair samples, the longer the time of the drug that is able to measure. Some hair lengths may take years to grow, and in some cases allow drug use for years.

Hair test for hair usually requires more strands of hair for the most accurate results. The standard test measures at least 50 strands of hair. The best samples come from the scalp, where the hair remains rooted for a long time. If strands are missing in the head, body hair samples are also able to return relatively accurate test results.

The

hair drug test is one of the better tests for Employers medicines, because of its difficulties to handle and the ability to detect drug history, even if it is not present in the system. FROMThere are ways to deprive the system of drugs to significantly increase the chances of browsing blood, saliva or urine, it is much more difficult to get rid of the strands of hair of any traces of drugs.
