Utilizing hair testing has emerged as a significant method for identifying drug and alcohol usage. Hair captures a prolonged history of alcohol and other substances by securing biomarkers within the fibers of the hair as it grows. When gathered near the scalp, hair can provide a detection period of up to roughly 3 months for alcohol and other drugs. The collection process for hair is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch section of around 200 hair strands (comparable to the size of a #2 pencil) near the scalp equates to 100mg of hair, the preferred amount for analysis and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. It's recommended to measure the specimen with a jeweler’s scale. If scalp hair is absent, an equivalent quantity of body hair can be used. When head hair is mentioned, it refers solely to scalp hair. Body hair encompasses all other hair kinds (facial, axillary, etc.).
Process Overview
The four principal phases in laboratory handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample entry into a lab’s system. This step involves confirming the sample was appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not included in an electronic chain of custody system.
Screening conducts an initial quick analysis for drugs of abuse. While Screening is an economical method to exclude drug usage for most samples, a positive screen requires confirmation to be valid in court. Therefore, any presumptive positive results in Screening necessitate further confirmation.
Should a sample show a presumptive positive during Screening, additional hair is retrieved from the original sample for Extraction. During this phase, drugs are extracted from hair at a much lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are washed before confirmation if needed. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: While frequently termed as "hair follicle tests", the analysis examines the hair strand and not the hair follicle beneath the scalp.
