Hair analysis is recognized as an effective method for identifying drug and alcohol usage. Hair captures a lengthy history of substances in its structure by integrating biomarkers into its strands. When sampled near the scalp, hair can offer up to about a 3-month evidence period for alcohol and drugs. It's simple to gather, challenging to tamper with, and straightforward to transport.
A 1.5-inch portion of roughly 200 hairs (comparable to a #2 pencil in thickness) near the scalp yields 100mg, the optimal amount for testing and verification. For EtG, supplementary, or tests exceeding 10 panels, a 150mg sample is advised. It is recommended to measure the specimen using a jeweler's scale. If head hair isn't accessible, an equivalent volume of body hair is acceptable. References to head hair imply scalp hair solely, whereas body hair encompasses other types (facial, underarm, etc.).
Process Overview
The primary stages in lab processing of a test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of entering a sample into a lab’s database. This step involves ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing missing data entry if the electronic system didn't cover it.
Screening performs an initial general assessment for substances of abuse. Although cost-effective for eliminating drug use in most cases, positive screenings must be confirmed for legal admissibility. Presumptive positive results from Screening need secondary validation.
When a Screening results in a presumptive positive, additional hair is extracted from the sample and prepared for Extraction. Drugs in this step are separated from hair at lower concentrations than with other methods (e.g., urine or saliva), highlighting hair drug screening as the most challenging technique.
Verification of any positive screening entails GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples are thoroughly cleaned before confirmation if necessary. The whole lab process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Note: Despite being commonly termed "hair follicle tests", the test examines the hair strand, not the follicle beneath the scalp.
