Can Hair From a Brush Be Used for a Drug Test?

American Screening Corporation mentioned that if you're considering working for a company that conducts drug tests, you may be pondering if brush hair can be used for a drug test. Employers frequently use urine tests to screen job candidates, determine whether employees have been using drugs, and follow workplace accidents.

Most drug tests only indicate whether substances were used within a specific time frame prior to the test. This is because many medications that are ingested are absorbed into the bloodstream and remain in the system for an extended period of time.

In contrast to urine, which only indicates when a substance was consumed and not when it was used, a hair follicle test reveals the exact day a sense was used. This is due to the fact that drug metabolites travel to every portion of the body, including the hair.

This means that drug residue will remain in your hair for months after you cease using. This is one of the reasons why employers prefer hair follicle drug tests over alternatives such as urine or oral secretions.

To achieve the most precise results, a hair sample must be 1.5 inches long and pencil-thick. This quantity may be collected from the head or other body parts, such as the underarms or arms.

The test will determine a 90-day substance history beginning on the date the hair sample was collected. This period can be lengthened if the model is taken from a body region where hair grows more slowly than on the scalp.

Take a small strand of hair from the crown of your scalp for this method. The piece will then be cut at an angle that will allow the lab to obtain a pure sample for analysis.

After the hair has been cut, it is placed in a secure receptacle and sent to the laboratory for examination. The laboratory will then send you a report that includes a positive or negative result for each drug class.

As one of the most hazardous occupations, testing hair follicles is a viable option for drug screening in the trucking industry. A driver under the influence of a controlled substance can cause a severe catastrophe and jeopardize their own safety as well as the reputation of their employer.

In addition, it is an excellent option for businesses that need to hire workers who can operate heavy machinery. This is especially true in the construction industry, where an error could result in an accident or financial loss.

Testing of hair follicles is the most effective method for substance screening. It is simple to obtain a pure sample, and the results are highly accurate. In addition, the risk of sample adulteration is significantly reduced when hair follicles are used instead of urine.
