Hair analysis is recognized as an effective means for detecting substance and alcohol consumption. Hair captures a prolonged record of alcohol and drug usage by embedding biomarkers within the growing hair shaft. When gathered near the head, hair can offer a detection timeframe of nearly three months for substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil thickness) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and verification. For EtG, additional assessments, and/or tests exceeding 10 panels, 150mg of hair is advisable. It's best to measure the specimen using a jeweler’s scale. If scalp hair isn't available, a similar amount of body hair may be used. Head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four key stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample within a lab's system. This involves ensuring the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional information not covered by an electronic chain of custody.
Screening is a preliminary check for drug abuse. Although Screening is a cost-effective method for eliminating drug usage in most samples, a positive result requires confirmation for legal acceptability. Any samples that test presumptively positive in Screening need further verification.
If a sample is found presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. This is where substances are extracted from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging to execute.
Verification of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.
