The hair drug test is perhaps the most trusted among all the drug testing methods being administered at present. Not only does the hair contain information about the history of drug use, it can also detect levels of heavy metals, date rape drugs, alcohol, antidepressants, poisons and other toxins that the body has taken in.
What can it detect?
Hair samples for drug testing are able to detect all major drug types, including cocaine, marijuana, opiates, amphetamine, methamphetamine, ecstasy and phencyclidine (PCP). Hair drug testing detects the smallest amounts of illicit substances which are held in the hair’s cortex.
How far back can it detect?
Among all the drug tests available, it provides the longest detection time. It can trace drug history back up to 90 days using only about two inches of hair, representing about 3 months of growth. Results from hair follicle drug testing are well trusted because there are no known adulterants for this kind of test. Shampoos, hair dyes,conditioners and other hair products do not affect the results of the drug tests.
How accurate is it?
Most companies now adapt hair follicle drug testing because it is very hard to fool and it is accurate in measuring the amount of drugs that a person has taken. Even though hair follicle drug testing is a much more expensive method, it provides a much better level of accuracy and significantly longer history. Despite several debates on the use of hair drug tests on teens by parents, hair drug testing remains to be the tool of choice to test their children or loved ones. It is accurate, yet can be done in the privacy of home. You can collect the sample yourself and send it to the laboratory in full confidentiality.
