Hair analysis is recognized as an influential method for identifying drug and alcohol consumption. Hair retains a historical record of substances by embedding biomarkers within its fibers. When collected near the scalp, hair offers a detection window of approximately three months for alcohol and drugs. Hair samples are straightforward to gather, relatively tamper-resistant, and simple to transport.
A 1.5-inch portion of about 200 hair strands (approximating the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, optimal for tests and verification. For EtG, extra tests, and panels exceeding 10, a 150mg sample is advised. Using a jeweler’s scale to measure the specimen is recommended. If head hair is lacking, an equivalent quantity of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" includes all other hair types (facial, axillary, etc.).
Process Overview
The drug testing procedure in the lab encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample into the laboratory system. This step ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any data gaps not covered by an electronic chain of custody system.
Screening performs a preliminary evaluation for substance abuse. Although screening is a cost-efficient technique to exclude drug use for most samples, any positive results must undergo confirmation for legal acceptance. Samples that preliminarily show positivity in screening require further verification.
Should a sample be tentatively positive during Screening, additional hair from the original collection is utilized for Extraction. This phase extracts drugs from the hair at lower concentrations compared to other samples (e.g., urine or oral fluid), making hair drug testing the most intricate method to execute.
Positive screening findings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples indicated as positive are cleaned as part of the confirmation. The laboratory workflow from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair classification and meets ISO / IEC 17025 accreditation standards.
