The utilization of hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering an extended timeline for detecting alcohol and drugs. When gathered near the scalp, hair can indicate usage over an approximately three-month span for alcohol and other substances. The collection process is straightforward, making hair samples hard to tamper with and simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (approximately the diameter of a number 2 pencil) from near the scalp, yields 100mg of hair, which is considered ideal for screening and confirmation purposes. For EtG, additional tests, and/or tests exceeding ten panels, a specimen weighing 150mg is preferred. It is advisable to weigh the specimen using a jeweler’s scale. If scalp hair is lacking, a comparable amount of body hair is acceptable. References to head hair specifically denote scalp hair. In contrast, body hair encompasses all other hair types, such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial incorporation of the sample into the laboratory system, ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing additional data inputs as necessary, unless provided by an electronic chain of custody.
Screening provides an expedited preliminary check for substance abuse. Although Screening offers an economical approach to dismiss drug usage for numerous samples, results indicating a positive require confirmation to be admissible in legal proceedings. Any samples showing presumptive positivity in Screening necessitate follow-up confirmation.
For those samples showing presumptive positivity during Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, the extraction of drugs from hair occurs at substantially lower concentrations than alternatives such as urine or oral fluid testing, which is why hair drug testing represents the most challenging methodology.
Confirmation of any positive findings from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptively positive samples undergo a washing process prior to confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is conducted in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
