Hair analysis has emerged as an effective method for identifying substance and alcohol usage. Hair offers an extended record of alcohol and drug consumption by embedding biomarkers within the fibers of the hair strand as it grows. When obtained near the scalp, hair can reveal up to around a three-month timeframe for detecting alcohol and drug usage. Hair is easy to gather, challenging to tamper with, and convenient to transport.
An ideal testing and confirmation require a 1.5-inch sample of nearly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp to yield 100mg of hair. For EtG, additional screenings, or tests exceeding 10 panels, 150mg of hair is advised. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair is not present, an equivalent volume of body hair may be used. The term "head hair" specifically pertains to scalp hair only, whereas "body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The four principal phases in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial intake of a sample into a laboratory's workflow. This process encompasses ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not provided by an electronic chain of custody system.
Screening provides an initial rapid evaluation for substances of abuse. Although Screening serves as a cost-effective method to exclude drug usage for most samples, a positive screen must be verified to be court-admissible. Any specimens that test presumptively positive during Screening necessitate a secondary verification.
Should a specimen be presumptively positive during the Screening phase, additional hair is extracted from the original sample and prepared for the Extraction process. During this phase, substances are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging method to execute.
Verification of a positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo cleaning prior to confirmation, as needed. The complete laboratory workflow from Accessioning to Confirmation undergoes review according to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
