Hair testing involves complete supervision by a parent. When using your at-home drug test kit, the hair sample is cut and directly placed into the collection container before being sent to the lab. The greatest benefit of a hair drug test like HairConfirm, which is readily available at CVS Pharmacy, is its long-term detection capabilities. It detects the use of a drug farther back in time than other forms of testing. A urine test, for example, lends a history of use stretching a mere 3-5 days before testing. Hair detects usage spanning as far as 90 days before testing, barring the most recent 5-7 days-the time it takes for hints of the drug to enter the bloodstream and travel to the hair.
Hair tests also detects more types of drugs (14) than urine (1-12) and can be used preventatively to deter teen drug use by providing an accountability factor. It takes only three to four hair drug tests per year to determine whether your teen is developing a pattern of usage, whereas a urine test must be administered almost weekly to establish the same history or pattern. When it comes to hair drug testing, an at-home drug test can range from $60 to $100, more than the average urine tests (about $30-$50). But when you consider that only three to four tests are needed yearly, the total spent on hair testing over the course of a year falls noticeably below that of urine testing.
