The utilization of hair testing is increasingly acknowledged as a robust means for identifying drug and alcohol consumption. This method captures a comprehensive timeline of substance use by embedding biomarkers within the fibers of the growing hair strand. Hair samples gathered near the scalp can reveal drug and alcohol presence over approximately a three-month span. Hair collection is straightforward, resistant to tampering, and convenient to transport.
A 1.5-inch segment comprising roughly 200 hair strands (comparable to the diameter of a #2 pencil) taken nearest to the scalp yields around 100mg of hair, forming the optimal quantity for analysis and validation. For EtG, supplementary tests, and/or assessments exceeding ten panels, 150mg of hair is suggested. Utilizing a jeweler's scale to measure the specimen is advised. Should scalp hair be inaccessible, an equivalent quantity of body hair may be utilized. References to head hair explicitly denote scalp hair, while body hair encompasses all other varieties (including facial and axillary hair).
Process Overview
The laboratory processing of a drug test result is comprised of four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial registration into a laboratory's management system. This step involves verifying that the sample was properly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody protocol.
Screening entails an initial brief assessment for potential drugs of abuse. While Screening presents a cost-effective method for eliminating drug use in most cases, any positive result necessitates confirmation to ensure legal admissibility. Samples with presumptive positive results in Screening must undergo secondary confirmation.
Should a sample be preliminarily identified as positive during Screening, additional hair is extracted from the original specimen for the Extraction process. Here, drugs are extracted from the hair at much lower concentrations compared to other methods (such as urine or oral fluid), marking hair drug screening as a challenging procedure to conduct.
The Confirmation of any positive Screening findings is achieved via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples identified as presumptive positives are washed prior to confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Limitations:
Note: While commonly called "hair follicle tests", the examination actually assesses the hair strand rather than the follicle under the scalp.
