Taking alcohol or drug tests used to involve no other substances than blood and urine, which are fairly reliable sources, of course, but not exactly something that is a delight to handle. These days, hair drug testing or the hair strand test is becoming the more commonly preferred way to test an individual for drugs or alcohol in his or her system. This should come as a relief for people who are squeamish about having blood extracted from their bodies and those who are unable to instantly produce the substance required for a urinalysis.
The hair strand test may still be unfamiliar for some people, which is why it is important for everyone to learn more about it in the event that they have to undergo the process. Simply put, this involves examining a person’s hair strands in order to determine if they have recently taken drugs or consumed alcohol. The procedure requires you to submit 90 to 120 strands of hair in order to produce a more accurate reading of substance levels, and these strands should at least be 1.5 inches long. The hair should also be cut quite close to the scalp in order to preserve the presence of any substances in the body.
Accuracy is one of the main advantages of the hair strand test. Because it can detect drug use up to 90 days prior to the test, it also has a much longer detection period. This is because hair takes time to grow, and any drugs or alcohol you might have consumed in the past couple of months will have embedded itself in your hair follicles, ensuring that your hair will contain metabolites from the drugs as it grows out of your scalp. The hair sample you submit for your hair strand test will be pulverized by the laboratory, a process that will eventually yield the metabolites present.
Keep in mind that even bald people are not saved from taking a hair strand test; body hair can always be used in lieu of hair on the head. This body hair can be collected from various parts of the body until an acceptable amount for the sample is achieved; anything from hair on the arms, chest, and legs can be used, although the hair strand test steers clear of pubic hair.
Some people unwilling to part with their hair wonder whether they can submit hair retrieved from combs and hairbrushes. The answer to this is no, because the hair you leave on them may have fallen off at different times and won’t match the hair you currently have, which will render the hair strand test results inconsistent. It is required to submit a fresh hair sample to ensure accurate results.
In a world of changing ethics and propelling questions hair follicle drug test has a variety of uses. A hair drug testing is something the athletic organizations, forensics, insurance companies and large corporations will need to be aware of. Hair drug testing is one of the top methods because it can provide an accurate history of use and is the longest lasting piece of evidence.
