Hair testing is recognized as an effective means for detecting the consumption of drugs and alcohol. Hair captures a long-term record of alcohol and other drugs by embedding biomarkers in the fibers of the growing hair strand. When gathered near the scalp, hair can supply a detection period of up to about 3 months for alcohol and additional drugs. Obtaining hair is straightforward, comparatively challenging to tamper with, and convenient to send.
A 1.5-inch section of approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for assessment and validation. For EtG, extras, and/or tests exceeding 10 panels, a 150mg sample is suggested. It is advisable to weigh the specimen using a jeweler’s scale. Should scalp hair be lacking, a proportionate amount of body hair can be gathered. When referencing head hair, this pertains solely to scalp hair. Body hair denotes all other hair categories (facial, axillary, etc.).
Process Overview
The core steps in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the fundamental processing of a sample within a laboratory’s system. This encompasses confirming that the sample was securely sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry not supplied by an electronic chain of custody system.
Screening consists of an initial rapid evaluation for drugs of abuse. While Screening efficiently rules out drug usage in most samples, a positive screen must be verified for legal acceptability. Samples that are presumptively positive in Screening require subsequent confirmation.
If a sample shows a presumptive positive during the Screening phase, additional hair is drawn from the initial sample and prepared for Extraction. At this stage, drugs are extracted from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which makes hair drug screening one of the most challenging methodologies.
Confirmation of any positive screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Note: Although often labeled as "hair follicle tests", the examination itself evaluates the hair strand and not the follicle beneath the scalp.
