Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a detailed timeline of alcohol and other drug use by embedding biomarkers within the hair's structure. When sourced near the scalp, hair can indicate substance presence for up to roughly three months. Hair collection is straightforward, challenging to falsify, and easy to transport.
A 1.5-inch segment comprising approximately 200 hairs (equivalent to a #2 pencil's girth) nearest to the scalp yields 100mg, the perfect amount for both preliminary and confirmatory analysis. For tests like EtG, enhancements, or those exceeding ten panels, a 150mg sample is preferred. Utilizing a jeweler’s scale is advisable for specimen weighing. Should scalp hair be absent, a comparable volume of body hair may suffice. References to head hair pertain solely to scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
The core stages in the laboratory evaluation of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory phase of integrating a sample into a lab's framework. Tasks encompass validating the sample’s proper sealing and dispatch, allocating a unique LAN (Laboratory Accessioning Number), and executing manual data inputs absent from an electronic chain of custody system.
Screening serves as an initial swift assessment for drug misuse. Although it offers a cost-effective approach to eliminate drug usage from most samples, positive screenings require confirmation to hold up in a legal setting. Samples indicating a presumptive positive status from Screening demand a subsequent confirmation process.
Should a specimen show a presumptive positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. This phase involves the extraction of drugs from hair at concentrations lower than those utilized in alternative processes (e.g., urine or oral fluid), marking hair drug analysis as a complex technique.
Any positive outcome from Screening undergoes confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples are cleansed prior to necessary confirmation tests. The comprehensive lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Limitations:
Note: Although commonly termed "hair follicle tests", the actual test examines the hair strand rather than the hair follicle beneath the scalp.
