Hair analysis is now widely recognized as a significant means for detecting substance and alcohol consumption. Hair captures a comprehensive history of substance use by holding biomarkers within its growing fibers. When gathered close to the scalp, it offers a detection range of roughly three months for alcohol and drugs. The collection of hair is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch section comprising roughly 200 strands (similar in size to a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for testing and validation. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg specimen is advised. Use a jeweler’s scale for precise weighing of the specimen. If scalp hair is missing, an equivalent amount of body hair may be utilized. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other hair (facial, axillary, etc.).
Process Overview
The analysis of a drug test result in the lab includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into the laboratory's system. This process includes ensuring that the sample is sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data entry not covered by an electronic chain of custody system.
Screening is a preliminary overview for substances of abuse. While cost-effective for ruling out drug presence in most samples, a positive find requires confirmation for legal acceptance. Presumptively positive samples in Screening need further confirmation.
If Screening results imply a positive, additional hair is sourced from the original sample for Extraction. During this phase, drugs are isolated from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), making hair drug testing the most complex methodology.
Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing positive are cleaned prior to confirmation as needed. The complete lab process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
