Hair drug testing is a popular method for screening employees for drugs, but it has its limitations. First of all, hair does not have the same potency as urine, so a single strand is not enough to test positive. You can learn more about drug testing kits here.
A lock of hair that is about the thickness of a pencil is sufficient. However, depending on the requirement, multiple samples may be required. Second, the hair grows on average one centimeter a month. Third, hair can be a great indicator of whether a person is using drugs.
Hair Drug Testing Does Not Need to be Segmented
In addition, hair drug testing does not need to be segmented. Many firms will test only a small number of metabolites for each drug group, while others will not test at all. This limited metabolite set may make it difficult to identify the client’s usage, so using a more comprehensive sample set may be better for the results.
DNA Legal uses an extended washing process that increases the likelihood of detecting the presence of drugs. The collection process is quick and painless, and the donor does not have to be under any pressure. The lab will collect hair from a variety of areas of the head.
Sometimes, the technician will leave the bald spot to collect hair from other parts of the body. The hair is then placed in a security envelope and sent for testing. Moreover, hair drug tests do not depend on the care of the donors’ hair. The results of a hair follicle drug test will show whether a person has used drugs within the past five to ninety days.
It is a Quick and Painless Process
Hair drug testing is a non-invasive, painless test that can be performed in the office. The results are typically available within 72 hours. The test will reveal if the person has used drugs or not. Once the result is available, the drug test will be able to tell the specific drugs that were used.
With proper testing procedures, inconclusive results are rare. A test that has been properly administered is more likely to provide accurate results. To determine if a person has drug use, they must have more than one strand of hair. Usually, the drug sample from a donor’s head will be discarded as it washes away.
If the strands are unidentified, they may be useless for the test. A hair sample can indicate whether or not a person has a substance in their system. The hair test is a reliable way to confirm the presence of certain drugs. The results of hair drug tests are based on a number of factors. A positive test is not necessarily indicative of drug use.
A negative test cannot be interpreted as proof of lack of exposure. For example, a negative test may be caused by an individual who has a history of using drugs. Hence, a person can have a positive or a negative result for a given drug. For this reason, a positive result does not guarantee that a person has no substance in his or her system.
It Can Identify Certain Drugs in a Person’s Hair
Hair drug testing is one of the few methods that can detect drugs in a person’s hair. It is a form of urine test, which is also available for detecting marijuana. It is possible to identify certain drugs in a person’s hair, but there is no way to ensure that it is completely clean.

As an additional benefit, hair tests can also detect certain types of drugs, such as opiates and amphetamines. In addition, they are highly accurate and can give companies information about current employees.
A hair follicle drug test is the most accurate method of drug testing, and it allows the employer to detect drug use as far back as 90 days. Because hair is so much more difficult to prepare for, it is difficult to cheat.
This type of test also requires a person to disclose any medications they take. If they have a history of addiction, their employer can ask them to take the test again. If their employee has a history of substance abuse, they may be required to disclose them.
