Hair analysis is now widely regarded as an effective method for identifying drug and alcohol usage. The composition of hair fibers captures biomarkers, offering a prolonged record of alcohol and other drug presence. When samples are taken near the scalp, hair can provide an approximate detection period of up to three months for alcohol and other drugs. Hair is straightforward to obtain, relatively resistant to tampering, and easy to transport.
A 1.5-inch segment comprising about 200 hair strands (roughly the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, which is ideal for initial and confirmatory screening. For EtG, additional testing, and/or assessments over 10 panels, 150mg of sample is advised. Using a jeweler’s scale for measuring the specimen is recommended. If scalp hair is absent, a comparable amount of body hair can be used. When referencing head hair, this pertains only to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedures for processing a drug test result involve four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab system. This process verifies whether the sample was appropriately sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data entries not covered by an electronic chain of custody system.
Screening consists of an immediate cursory analysis for substances of abuse. Although cost-effective for largely ruling out drug use in most samples, any positive screening results must be confirmed to be valid in a legal context. Samples with presumptive positive results during Screening necessitate secondary confirmation.
For samples returning a presumptive positive in Screening, more hair from the original sample is prepared for Extraction. This phase involves concentrating drugs from hair at substantially lower concentrations compared to other methods (like urine or oral fluid), explaining why hair drug testing is a highly intricate methodology.
Confirmation of any positive screening findings employs GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation where required. From Accessioning to Confirmation, the full laboratory process is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Note: Frequently termed "hair follicle tests", this test evaluates the hair strand rather than the follicle beneath the scalp.
