Hair analysis has gained recognition as an effective method for identifying alcohol and drug usage. Hair captures a comprehensive timeline of substances by embedding biomarkers within the hair's growing strands. When taken near the scalp, hair can reveal alcohol and drug presence for a period extending up to three months. Hair is straightforward to obtain, somewhat hard to tamper with, and convenient to transport.
An optimum sample for testing and verification consists of a 1.5-inch portion of roughly 200 hairs (similar in size to a #2 pencil) closest to the scalp, providing 100mg of hair. For EtG, supplemental tests, or panels exceeding ten, a 150mg amount of hair is advisable. It is preferable to measure the sample using a jeweler’s scale. If scalp hair can't be collected, a comparable amount of body hair is suitable. Head hair specifically refers to scalp hair, while body hair includes all other types (such as facial or axillary).
Process Overview
The four essential stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial sample integration into a laboratory setup. This phase ensures the sample's secure seal and proper shipping, allocates a random LAN (Laboratory Accessioning Number), and facilitates any additional data management not handled by an electronic custody chain system.
Screening provides a preliminary inspection for substance abuse. While Screening is an economical method to exclude drug presence in most cases, a positive screen necessitates verification for legal acceptance. Samples that produce a presumptive positive during Screening must undergo further confirmation.
Should a specimen yield a presumptive positive at the Screening phase, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are separated from hair at notably lower concentrations than in other methods (like urine or oral fluid), thus making hair drug screening the most challenging technique to execute.
Verification of any preliminary positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples are cleansed prior to confirmation if required. The full lab procedure from Accessioning to Verification is assessed under both the CAP (College of American Pathologists) Hair designation along with accreditation to ISO / IEC 17025 specifications.
