Quick answer
The 12 Panel Hair Drug Test is a broad screen that looks for twelve classes of drugs in a small hair sample. Hair testing can reflect a longer period of exposure than urine or blood, which is why it is used in some workplace, legal, and personal testing situations. Collection is quick and does not require a urine sample.
What this test measures
Hair testing works differently from urine or blood screening. As hair grows, substances and their metabolites can become incorporated into the hair shaft, so a sample can reflect a longer window of exposure. Laboratories typically analyze the segment of hair closest to the scalp, which represents roughly the most recent three months of growth.
The collection is simple and non-invasive. A trained collector cuts a small amount of hair close to the scalp, usually from the back of the head, and sends it to the laboratory. The panel screens for twelve drug classes, including amphetamines, barbiturates, benzodiazepines, cocaine, MDMA, methadone, methaqualone, opiates, PCP, propoxyphene, THC, and 6-acetylmorphine.
Hair testing may be requested when a longer detection window is useful, such as in some pre-employment programs, legal matters, or personal checks. Results depend on laboratory methods and cutoffs, and they should be interpreted with a qualified healthcare provider. Hair treatments and environmental exposure are among the factors that laboratories consider during analysis.
