Hair analysis is recognized as an effective means for identifying substance use. Hair offers a retrospective account of substance exposure by embedding biomarkers within the hair shaft. When obtained near the head, hair samples can present a detection period extending up to roughly three months for alcohol and various substances. Hair collections are straightforward, relatively tamper-resistant, and simple to transport.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (approximately the diameter of a #2 pencil) harvested close to the scalp yields about 100mg of hair, which is the optimal portion for both screening and confirmation tests. For EtG, supplementary analyses, or screenings exceeding 10 panels, 150mg of the specimen is advisable. It is recommended to weigh the collection using a jeweler’s scale. In cases where scalp hair is absent, an equivalent quantity of body hair may be used. When mentioning head hair, we are referring exclusively to scalp hair. Body hair encompasses any other hair types (such as facial and axillary hair).
Process Overview
The primary steps in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the intake and initial handling of a specimen within a lab's system. This step encompasses the verification of proper sample sealing and dispatch, the assignment of a unique LAN (Laboratory Accessioning Number), and the completion of any necessary data input not addressed by a digital custody chain system.
Screening consists of a preliminary swift assessment for drug substances. Although Screening represents a cost-efficient method to dismiss drug consumption in most samples, a positive finding during Screening necessitates confirmation for legal acceptability. Samples that show presumptive positivity during Screening require additional confirmation.
Should a sample display presumptive positivity in the Screening phase, additional hair is drawn from the original collection for Extraction preparation. In this step, substance extraction from hair occurs at significantly lower concentrations compared to other methods (such as urine or oral fluid), explaining why hair drug analysis is considered the most complex method to conduct.
Confirmation for any positive screened outcome takes place through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

Note: Despite being termed "hair follicle tests", the procedure analyzes the hair shaft rather than the follicle beneath the scalp.
