Hair analysis has emerged as an effective means for detecting substance use involving drugs and alcohol. Hair captures a long-term record of alcohol and other substances by embedding biomarkers within the strands as hair grows. When gathered close to the scalp, hair can present a detection timeline of approximately 3 months for substances including alcohol. Hair collection is straightforward, challenging to tamper with, and simple to transport.
An ideal specimen for testing comprises a 1.5-inch section of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp, resulting in 100mg of hair. For EtG tests, additional parameters, or panels exceeding 10, a 150mg sample is advised. Utilizing a jeweler’s scale is suggested for weighing the sample. When scalp hair is unavailable, the same quantity of body hair may suffice. References to head hair pertain solely to scalp hair. In contrast, body hair includes all other hair types (facial, axillary, etc.).
Process Overview
Laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a laboratory system. This involves ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening offers an initial fast assessment for potential substance abuse. While Screening is an economical method for eliminating drug use in most samples, a positive screening requires confirmation for court validity. Presumptively positive samples from Screening necessitate further confirmation.
In the case of a presumptively positive result during Screening, additional hair is sourced from the original specimen for Extraction preparation. Here, drug compounds are extracted from hair at significantly lower concentrations relative to other methods (e.g., urine or oral fluid), making hair drug testing one of the most complex methodologies.
Positive screening confirmations are carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples deemed presumptively positive undergo washing before confirmation as required. The entire lab process, from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation standards.
