Hair analysis is increasingly recognized as a potent means for identifying drug and alcohol consumption. It captures a historical record of substance usage by containing biomarkers within the structure of the hair's growing fibers. When sourced near the scalp, hair can offer nearly a three-month timeframe for detecting substances like alcohol and drugs. The collection of hair is straightforward, relatively challenging to tamper with, and simplistic to transport.
A small section measuring 1.5 inches, approximately composed of 200 hair strands (roughly comparable to a #2 pencil's width) closest to the scalp yields 100mg of hair, considered the optimal sample for testing and affirmation. For assessments like EtG, additional tests, and those over 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for measuring the sample is suggested. In the absence of scalp hair, an equivalent mass of body hair can be gathered. References to head hair specifically denote scalp hair, whereas body hair pertains to other varieties (facial, armpit, etc.).
Process Overview
The primary phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a lab's system, ensuring proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling additional data requirements not met by an electronic custody chain system.
Screening offers a preliminary assessment for substance misuse. Though cost-efficient for negating drug use in most samples, a positive screen necessitates verification for legal acceptability. Any samples testing positively in Screening require subsequent confirmation.
Should a sample yield a presumptive positive result in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are drawn from hair at significantly reduced concentrations compared to other procedures (e.g., urine or oral fluid), making hair drug analysis a highly complex technique.
Confirmation of any positive screen result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are thoroughly washed as needed before confirmation. The complete lab process covering from Accessioning to Confirmation is monitored under the CAP's (College of American Pathologists) Hair category and accredited following ISO / IEC 17025 guidelines.

Note: Although often labeled as "hair follicle tests", these assessments focus on the hair strand rather than the follicle beneath the scalp.
