Hair testing is increasingly viewed as an effective method for identifying drug and alcohol usage. Hair captures a comprehensive timeline of alcohol and other drugs, as biomarkers are ensnared within the fibers of the hair as it grows. Collected near the scalp, hair can provide a detection period of up to three months for alcohol and other drugs. The collection process is straightforward, the specimens are challenging to alter, and they are easy to transport.
A 1.5-inch snippet containing around 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp offers 100mg of hair, which is the optimal sample for testing and confirmation. For EtG, additional tests, or those beyond 10 panels, a 150mg sample is advisable. It is suggested to measure the sample on a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair can be gathered. Head hair refers exclusively to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory process for handling a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary handling of a sample within a lab’s system. This process confirms the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and finishes any needed data input not included by an electronic chain of custody system.
Screening provides an initial, rapid assessment for potential drug abuse. While Screening is a cost-effective measure to dismiss drug usage in most samples, a positive result requires confirmation for court acceptance. Samples indicating possible positivity in screening must undergo secondary verification.
Should a sample appear positive at the Screening stage, additional hair is taken from the original sample for the Extraction stage. Here, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which makes hair drug testing a complex methodology.
Confirmation for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples are washed before confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and with accreditation to ISO / IEC 17025 standards.
