Hair analysis has gained recognition as an effective method for detecting substance use. Hair retains a chronological record of alcohol and drug exposure by incorporating biomarkers within the hair shaft's strands. When harvested near the scalp, hair offers an approximate 3-month timeframe for detecting alcohol and various drugs. It is straightforward to gather, relatively resistant to tampering, and simple to transport.
A 1.5-inch segment containing approximately 200 hair strands (comparable to a #2 pencil's size) nearest the scalp provides 100mg of hair, the preferred sample for both screening and validation. For EtG, add-ons, and panels beyond 10 tests, a sample weighing 150mg is advised. To ensure precision, the specimen should be weighed with a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be utilized. ‘Head hair’ refers specifically to scalp hair, while ‘body hair’ includes all other hair categories (such as facial or axillary hair).
Process Overview
The laboratory processing of drug tests involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing stage of integrating a sample into a laboratory's framework. This stage involves confirming proper sealing and shipping of the sample, assigning a random Laboratory Accessioning Number (LAN), and inputting any supplementary data not already included by an electronic chain of custody system.
The Screening phase provides an initial rapid assessment for illegal drug presence. Although it is a cost-efficient method to exclude drug use in most samples, a positive screening necessitates further confirmation for legal proceedings. Samples that test positively during Screening require additional verification.
Should a sample test presumptively positive during Screening, additional hair from the original specimen is extracted for the Extraction stage. This phase isolates drugs from hair at significantly lower concentrations than other testing methods like urine or oral fluid, highlighting why hair drug screening is considered the most challenging method to execute.
Any positive findings from Screening are verified through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are thoroughly cleansed before confirmation, as required. The entire process, from Accessioning to Confirmation, undergoes review in adherence to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Commonly termed "hair follicle tests", the test examines the hair shaft itself, not the follicle beneath the scalp.
