Hair analysis is recognized as a significant method for identifying substance and alcohol consumption. By capturing biomarkers within the fibers of the developing hair, hair offers an extended historical record of alcohol and drug use. When gathered near the scalp, hair can reveal alcohol and drug presence for a duration of up to roughly three months. Hair collection is straightforward, relatively hard to tamper with, and convenient for transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to a #2 pencil), taken nearest to the scalp, provides 100mg of hair, which is the optimal sample for testing and verification. For EtG, additional tests, and/or screenings exceeding 10 panels, a specimen of 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a proportional quantity of body hair may be used. When mentioning head hair, it specifically implies scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The crucial steps in processing a drug test result in a laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary processing phase of a sample entering a laboratory’s framework. This step ensures the sample is properly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and fills in any necessary data absent from an electronic custody system.
Screening offers an initial rapid assessment for drugs. Though Screening is a cost-effective method to exclude drug consumption in most samples, a positive result must be verified for legal credibility. Samples preliminarily positive in Screening require confirmation.
For samples preliminarily positive during Screening, additional hair is extracted from the original specimen for further preparation in Extraction. Drugs are extracted at a lower concentration from hair than in other methods (e.g., urine or saliva), making hair testing the most intricate to conduct.
Any positive Screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples preliminarily positive undergo washing before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is evaluated per the CAP (College of American Pathologists) Hair criteria and accords with ISO / IEC 17025 standards.
