Hair screening is increasingly recognized as an effective method for identifying drug and alcohol consumption. The strands capture biomarkers within their fibers, offering a long-term record of substance use. Collected near the scalp, hair can reveal drug and alcohol usage over an approximately three-month period. Hair is easy to gather, relatively resistant to tampering, and convenient for transport.
A 1.5-inch segment of around 200 hairs (roughly comparable to a #2 pencil in thickness) nearest to the scalp is needed to obtain 100mg of hair, which is optimal for both initial tests and verification. For EtG, additional assessments, or procedures exceeding 10 panels, a 150mg specimen is advisable. Utilizing a jeweler’s scale is suggested for specimen measurement. If scalp hair cannot be obtained, an equivalent quantity of body hair is a suitable alternative. References to head hair pertain specifically to scalp hair. Conversely, body hair encompasses facial, axillary, and other types.
Process Overview
Four primary stages exist in the laboratory analysis of a drug test, namely Accessioning, Screening, Extraction, and Confirmation.
Accessioning establishes the initial integration of a sample into a laboratory system. This process involves verifying the sample’s seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data not included by an electronic chain of custody application.
Screening serves as a preliminary, rapid evaluation for substances of abuse. Although cost-effective for excluding drug usage in most cases, positive screenings require verification for legal validity. Samples testing presumptively positive in Screening need subsequent affirmation.
If a sample tests presumptively positive during Screening, additional hair from the original specimen undergoes preparation for Extraction. Here, drugs are derived from hair at substantially lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug testing the most challenging to execute.
Confirmation of any positive Screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples testing presumptive positive are washed based on necessity. The laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
