Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair archives long-term data of alcohol and other substances by sequestering biomarkers within its growing fibers. When taken near the scalp, hair offers a detection window of nearly 3 months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch segment containing approximately 200 strands of hair (around the size of a #2 pencil) near the scalp delivers 100mg of hair, the preferred sample for evaluation. For EtG, add-ons, and/or tests beyond 10 panels, 150mg is advised. It is best to use a jeweler’s scale for weighing the sample. If head hair is not accessible, an equivalent quantity of body hair can be collected. 'Head hair' denotes scalp hair exclusively. 'Body hair' encompasses all other types (facial, axillary, etc.).
Process Overview
The four primary stages in lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample within a lab's system. This step includes checking that the sample has been sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not supported by an electronic chain of custody system.
Screening is an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient way to dismiss drug presence in most samples, a positive result must be validated to stand in court. Any samples registering presumptively positive in Screening require further confirmation.
When a sample is presumptively positive during Screening, additional hair is extracted from the original specimen for Extraction. In this phase, drugs are sourced from hair at much lower levels compared to other approaches (ex. urine or oral fluid), making hair drug analysis the most complex to execute.
Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples noted as presumptively positive undergo washing before confirmation as necessary. The full lab procedure from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
