Hair analysis has gained recognition as an effective technique for detecting drug and alcohol consumption. By trapping biomarkers in the strands, hair provides a prolonged timeline of alcohol and other drugs usage. When taken from close to the scalp, it can facilitate a detection timeframe of up to roughly three months for alcohol and other drugs. Hair is straightforward to gather, somewhat challenging to tamper with, and uncomplicated to transport.
A sample of 1.5 inches, comprising approximately 200 hair strands (roughly the girth of a #2 pencil) nearest to the scalp, will yield 100mg, which is the optimal quantity for screening and validation. For EtG, supplementary tests, and/or screenings exceeding 10 panels, a specimen of 150mg is advised. The specimen can be weighed on a jeweler’s scale. If scalp hair is not obtainable, an equivalent quantity of body hair is permissible. When mentioning head hair, it specifically refers to scalp hair alone, while body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The key stages involved in the laboratory procedures for drug test results consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a specimen into a laboratory’s system. This step verifies that the specimen was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry omitted by an electronic chain of custody system.
Screening includes a swift preliminary assessment for drugs of abuse. Although Screening offers a cost-efficient means to negate drug usage in most specimens, a positive screen requires confirmation to be legally admissible. Samples that yield a presumptively positive outcome in Screening necessitate additional confirmation.
If a sample is indicated as presumptively positive during the Screening phase, additional hair is collected from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at a significantly lower concentration than found in other methodologies (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to execute.
Confirmation of any positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples yielding presumptive positive results undergo washing prior to confirmation, as needed. The entire laboratory process from Accessioning to Confirmation is conducted under the scrutiny of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Note: While commonly called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
