Hair analysis is regarded as an effective method for identifying substance use. Hair strands encapsulate biomarkers within their fibers, providing a comprehensive long-term history of drug and alcohol intake. When hair is sourced close to the scalp, it offers a detection timeframe of up to 3 months for drugs and alcohol. The collection process is straightforward, tampering is difficult, and transportation is convenient.
A sample length of 1.5 inches, containing roughly 200 hair strands (comparable to a #2 pencil's diameter) proximal to the scalp yields the optimal 100mg of hair necessary for both screening and confirmation procedures. For EtG, additional tests or those exceeding 10 panels, a minimum of 150mg is advised. It is recommended to measure the specimen using a jeweler’s scale. Should scalp hair be inaccessible, body hair of equal quantity is a permissible alternative. The term 'head hair' specifically denotes hair from the scalp. Other categories include body hair, encompassing types such as facial and axillary hair.
Process Overview
The processing sequence of laboratory drug testing entails four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample is initially integrated into a laboratory’s workflow. Tasks include verification of the sample's proper sealing and shipping, allocation of a unique LAN (Laboratory Accessioning Number), and completing any data entry absent in electronic custody chain systems.
Screening constitutes the preliminary assessment for substance abuse. While cost-efficient for ruling out drug presence in numerous cases, a positive screen necessitates further confirmation for legal acceptability. Samples categorized as presumptively positive in Screening require follow-up through additional verification.
Should a specimen yield a presumptive positive at the Screening stage, additional hair is extracted from the initial collection and processed for Extraction. This phase involves the withdrawal of drugs from hair at concentrations lower than other methods (e.g., urine or oral fluid), underscoring why hair drug testing is one of the more challenging methodologies.
Positive screening confirmations utilize GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive specimen undergoes washing before confirmation if necessary. The entire sequence from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Note: Though colloquially termed "hair follicle tests", the analysis targets the hair strand rather than the scalp's follicle
