The utilization of hair testing has increasingly become recognized as a significant method for uncovering alcohol and drug usage. Hair retains a historical record of drug and alcohol presence by embedding biomarkers within the hair strand fibers. When harvested near the scalp, hair can deliver a detection duration of up to nearly three months for substances like alcohol and other drugs. Collecting hair is straightforward, challenging to tamper with, and easy to transport.
An optimal 1.5-inch segment composed of approximately 200 hairs (comparable to the width of a #2 pencil) nearest the scalp provides 100mg of hair, ideal for both screening and verification purposes. For EtG, additional tests, and/or tests beyond 10 panels, it is suggested to obtain 150mg of the sample. Measuring the sample on a jeweler’s scale is advised. Should scalp hair be inaccessible, a corresponding amount of body hair may serve as an alternative. By 'head hair,' we specifically mean scalp hair. 'Body hair' encompasses all other hair categories (such as facial, axillary, and so forth).
Process Overview
The principal steps in processing a drug test result in a laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase that processes the sample within the lab system. This step ensures the sample was properly sealed and transported, assigns it a Laboratory Accessioning Number (LAN), and fills in any additional data not captured by an electronic chain of custody system.
Screening serves as a preliminary step to swiftly identify drugs of abuse. Though cost-efficient for eliminating the majority of negative samples, a positive screen must be confirmed for legal acceptance. Any samples indicating a presumptive positive in Screening must undergo further confirmation.
For samples showing presumptive positivity during Screening, additional hair from the original sample is utilized for Extraction, wherein drugs are isolated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), illustrating hair drug screening's complexity.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleaned before confirmation, as needed. The complete lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation alongside accreditation to ISO / IEC 17025 standards.

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