Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the strands of growing hair, a comprehensive record of alcohol and drug use is formed. When taken near the root, hair can offer about a three-month timeframe for detecting alcohol and other substances. Collection of hair is uncomplicated, not easily tampered with, and simple to transport.
A sample of 1.5 inches with around 200 strands (approximately the thickness of a #2 pencil) next to the scalp provides 100mg of hair, which is optimal for testing and confirmation. For EtG, additional testing, or panels beyond 10, a 150mg sample is advised. It's suggested to measure the sample with a jeweler's scale. In cases where head hair is not an option, a similar amount of body hair can be used. Head hair specifically refers to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary steps in laboratory analysis of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of samples into the lab's framework. This entails confirming proper sealing and shipping of the specimen, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.
Screening is a swift method to identify drugs of abuse. While it is a cost-effective measure to dismiss drug use in the majority of samples, a positive screen must be confirmed for legal validity. Any samples marked as possibly positive during Screening require further confirmation.
If presumptive positivity occurs during Screening, additional hair is extracted from the primary sample and prepared for Extraction. Here, substances are extracted from hair at significantly lower levels than alternative methods (e.g., urine or oral fluid), highlighting why hair drug testing is the most challenging method to conduct.
Any positive screen result is verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed to be positive undergo washing before confirmation as necessary. Each step from Accessioning to Confirmation is inspected according to CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although referred to as "hair follicle tests," the analysis pertains to the hair strand itself, not the follicle beneath the scalp.
