Hair analysis is increasingly recognized as an effective means for detecting drug and alcohol consumption. Hair captures long-term evidence of substances by embedding biomarkers within the strands' fibers. When sampled near the scalp, hair offers a detection range of up to three months for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A hair sample of 1.5 inches, consisting of around 200 strands (roughly the girth of a #2 pencil), provides 100mg of hair, which is optimal for testing and verification. For EtG tests, optional extensions, or panels exceeding 10, a 150mg sample is suggested. It's advisable to measure the sample using a jeweler’s scale. If scalp hair is absent, a comparable quantity of body hair can be obtained. Head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, underarm, etc.).
Process Overview
The four primary phases in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where the sample enters the lab system. The process involves verifying the integrity of the sample's sealing and transportation, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any extra information not covered by an electronic custody chain.
Screening provides an initial rapid assessment for substance abuse. Although Screening is economical for excluding drug usage in most samples, positive findings must be verified for legal acceptance. Samples testing positive in Screening necessitate confirmatory testing.
If the Screening phase suggests a positive result, additional hair is used from the initial sample for Extraction. This stage isolates drugs from hair at lower concentrations than other methods (e.g., urine or saliva), making hair analysis the most challenging method.
Verification of any positive screening outcome is completed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples suggesting positivity undergo cleansing before confirmation as required. The process from Accessioning through Confirmation complies with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
