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.

How to prepare
No fasting or special preparation is needed. Hair should be clean and dry at collection, and recent chemical treatments may affect analysis, so inform the collector if applicable. Follow the collection instructions provided by the laboratory.
Understanding your results
Turnaround is typically one to three business days. A non-negative screening result usually requires confirmation before it is considered final, and results should be interpreted by the ordering organization or a qualified professional.

Frequently Asked Questions
How far back does a hair drug test look?
It generally reflects exposure over roughly the past few weeks to months, depending on hair length and growth rate.
Can hair treatments affect the result?
Bleaching, dyeing, or relaxing can influence drug levels in hair, so disclose recent treatments to the collector.
Is a hair test better than a urine test?
Each has strengths. Hair offers a longer detection window, while urine is better for very recent use.
How much hair is needed?
Only a small sample, roughly the thickness of a pencil, is collected close to the scalp.
Are presumptive results confirmed?
Screening results that are not negative are commonly confirmed with a second, more specific method.
