10/20/2022 0 Comments How Hair Drug Tests Are ReportedUnlike urine drug tests, hair tests can identify drug use up to 90 days prior to a test. However, they can't pinpoint the exact date that you first used a drug. Instead, they detect a pattern of repeated drug use over a 90-day period. Hair grows at different rates, so it's not always possible to detect a particular drug at its earliest onset.
Hair drug test results are reported either as a negative or a positive. A negative result means that no drugs were found in the sample, which doesn't mean the donor has never used drugs. If a positive result comes back, the test found a trace amount of a drug. However, this cutoff value may vary from lab to lab. Normally, a positive drug test is confirmed by a second test, usually within 72 hours. This second test will identify the specific drug used. Although this isn't an ideal scenario, it's rare for a hair drug test to produce inconclusive results, especially if testing is performed correctly. A hair drug test can identify drug abusers by examining the metabolites in hair. This is the most accurate way of identifying drug abusers, and can report up to 90 days of drug use. It also reports whether the user took drugs at one time or over the course of one year. A hair drug test can reveal more than one substance, so it's important to read the results carefully. A positive result can make your drug use history clearer. Hair testing results can provide a more comprehensive picture than a urine or blood test. And if you don't take drugs, you'll have a better chance of being found clean. And if your results are positive, it will be reported to you in a professional manner. Hair drug testing is a legal option for truckers, and several large trucking companies are now using hair drug tests in lieu of urine drug tests. Companies cite safety and cost as reasons for implementing this practice. However, hair tests may not be perfect and may discriminate against people with dark skin or dark hair. Hair testing is inconsistent with self-reports, so results can be inaccurate. One study found that a large percentage of participants self-reported drug use but had hair tests that were negative. This study found that hair testing was a poor indicator of drug use for marijuana and cocaine users, and that hair test results were not always consistent with self-reports. Hair follicle tests have a longer detection window than urine tests. A drug may stay in a person's hair for seven to 10 days after exposure. This makes hair drug tests a good option for employers or parents who want to detect drug use in their staff. They can also determine the frequency of drug use. The most common Hair Drug Test is a five-panel drug test. This test can detect opiates, cocaine, THC, and amphetamines.
