Hair follicular analysis is increasingly regarded as a robust method for identifying substance and alcohol consumption. Hair captures a prolonged record of alcohol and drugs by embedding biomarkers within the strands of progressively growing hair. When collected near the scalp, hair can indicate a detection window for alcohol and drugs of roughly three months. Hair collection is straightforward, somewhat tamper-resistant, and convenient to transport.
A sample measuring 1.5 inches consisting of about 200 hair strands (approximating the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional screenings, or tests exceeding 10 panels, 150mg of the specimen is advisable. We suggest weighing the specimen on a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair may be used. By head hair, we exclusively mean scalp hair, whereas body hair refers to any other hair categories (facial, axillary, etc.).
Process Overview
The key phases in the lab handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
The Accessioning phase includes the initial handling of a specimen into a laboratory’s records. It involves ensuring the specimen was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data input not already provided by an electronic chain of custody system.
Screening entails an initial brief assessment for drugs of abuse. While Screening offers a financially sensible method to preclude drug usage for the bulk of samples, a positive screen requires confirmation to be lawful in court. Presumptively positive samples in Screening necessitate a secondary confirmation.
For samples presumptively positive at the Screening stage, more hair is taken from the initial sample for Extraction. In this phase, drugs are withdrawn from hair at notably lower concentrations than those in alternate methodologies (e.g., urine or oral fluid), underscoring why hair drug screening is the most intricate method to execute.
Positive screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation if required. The laboratory process spanning Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 standards.
