Hair analysis has emerged as a potent means for the identification of drug and alcohol consumption. Hair retains a long-term record of alcohol and other substances by capturing biomarkers within the strands as they grow. When gathered near the scalp, hair can offer up to a 3-month timeframe for alcohol and drug detection. Hair collection is straightforward, relatively immune to tampering, and convenient for shipping.
A sample measuring 1.5 inches with approximately 200 hair strands (roughly the width of a #2 pencil) near the scalp provides 100mg of hair, which is the optimal quantity for analysis and verification. For EtG, additional tests, or screenings exceeding 10 panels, 150mg of the sample is advisable. It’s suggested to measure the sample using a jeweler’s scale. In cases where scalp hair is not available, a similar quantity of body hair may be used. Head hair refers specifically to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory process of a drug test result encompasses four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a laboratory’s system. This process includes confirming the sample's secure sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any auxiliary data input absent from an electronic chain of custody setup.
Screening entails an initial rapid assessment for substances of abuse. While Screening serves as a cost-effective method to dismiss drug use in most cases, a positive outcome in screening requires confirmation to be legally viable. Samples with preliminary positive results in Screening necessitate further validation.
Should a sample yield a presumptive positive in the Screening phase, an additional portion of hair is extracted from the initial sample for the Extraction process. Here, drugs are isolated from hair at significantly reduced concentrations compared to other techniques (like urine or oral fluids), making hair drug screening one of the most challenging methodologies.
Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive screenings are cleansed prior to confirmation if required. The comprehensive laboratory process from Accessioning to Confirmation undergoes review adhering to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Limitations:
Note: Commonly misidentified as "hair follicle tests", the analysis actually evaluates the hair shaft rather than the follicle beneath the scalp.
