Hair analysis has emerged as a potent method for identifying drug and alcohol usage. Hair offers a comprehensive history of alcohol and other substances by trapping biomarkers within the hair strand as it grows. When collected near the scalp, hair can show drug and alcohol presence for up to about three months. The collection of hair is straightforward, challenging to tamper with, and easy to send.
An ideal sample consists of a 1.5-inch segment of around 200 hair strands (similar in thickness to a #2 pencil) cut closely to the scalp, yielding approximately 100mg, suitable for both screening and confirmation. For tests like EtG, add-ons, or more than 10 panels, a 150mg specimen is advised. It's recommended to use a jeweler’s scale to weigh the sample. If scalp hair is unavailable, an equivalent amount of body hair can be used. References to head hair imply scalp hair, while body hair encompasses all other hair varieties (face, armpits, etc.).
Process Overview
Drug test processing encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves recording a sample into a lab system. This phase includes confirming the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data not accounted for by an electronic custody chain system.
Screening provides a preliminary assessment for drug abuse. While it efficiently rules out drug use in most samples, any positive indications require confirmation for legal validity. Samples presumed positive during Screening necessitate further confirmation.
A sample identified as potentially positive in Screening proceeds to Extraction, where additional hair is taken from the initial sample and prepped. Here, drugs are derived from hair at a considerably lower concentration compared to methods like urine or oral fluids, making hair drug tests complex to perform.
Confirmation of positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing prior to confirmation when necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair specifications and accreditation to ISO / IEC 17025 standards.
