Drug testing can sometimes lead to sticky situations, especially when the reliability of the test is questionable. One method of testing is done using hair, and this is actually one of the most reliable drug tests today.
Hair can be collected anywhere around the patient’s body. It doesn’t have to be just hair on his head. If he shaved his head before testing, you can take some hair from his face, arms, or legs. Of course, you would need a substantial amount of hair for the testing to have valid results, especially if the hair that you collected is shorter than needed.
Another clear advantage is that hair takes up to 90 days to detect drug use. Other forms of testing that utilize urine and blood have only a maximum detection period of 7 days, which is just a blink of an eye for hair drug testing. Not only can you determine drug use, but you can also find out how long the person has been using drugs.
Of course, with its advantages over other testing methods, one can expect it to be more expensive. Despite the difference in price, it is generally worth it. The reliability of the test offsets its cost.
With these things in mind, it is not hard to see why hair drug testing is becoming more and more popular as a preferred testing method. The source material is readily available at any time, since everyone has hair somewhere on their bodies, and the detection window for drug use is a lot longer than when you use blood or urine.
