Quick answer
This panel analyzes a small hair sample for traces of common drugs and their metabolites. Because substances are deposited in hair as it grows, the test can reflect use over a longer period than urine or blood tests. Results are reported to the ordering person or organization and interpreted in the appropriate context.
What this test measures
Hair testing works because drugs and their breakdown products circulate in the bloodstream and become incorporated into the growing hair shaft. A sample collected close to the scalp reflects recent weeks to months of exposure, depending on hair length. The panel screens for several common classes of substances in a single analysis.
Collection is simple and non-invasive: a small amount of hair is cut close to the scalp, usually from the back of the head, and sent to the laboratory. Screening may be followed by confirmatory testing on the same sample when a result requires verification. Detection windows depend on hair growth rates and individual factors.
People order hair drug testing for workplace programs, personal peace of mind, or situations where a longer detection window is useful. Because results can have significant consequences, they should be reviewed carefully and, where needed, confirmed with an appropriate professional.
