Hair testing has emerged as a significant method for identifying alcohol and drug consumption. Hair captures a timeline of substance use by embedding biomarkers within the hair strand as it grows. When hair is taken from near the scalp, it offers a detection period of up to about 3 months for drugs and alcohol. Collecting hair is straightforward, somewhat hard to tamper with, and easy to send.
A 1.5-inch section consisting of roughly 200 hair strands (resembling the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect quantity for testing and confirmation. For EtG, supplementary tests, and/or panels beyond 10, a specimen of 150mg is advised. It’s suggested to weigh the sample using a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be used. References to head hair mean only scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The key steps in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample within the lab's system. This incorporates ensuring the sample is sealed and sent correctly, attributing a random LAN (Laboratory Accessioning Number), and finalizing any other data entry not covered by an electronic custody system.
Screening offers an initial rapid evaluation for drugs of abuse. Although Screening efficiently excludes drug use in most samples, positive screens must be confirmed to hold up in court. Samples that are tentatively positive during Screening require an additional confirmation step.
Should a sample be preliminarily positive in Screening, additional hair is separated from the original specimen and readied for Extraction. This phase involves extracting drugs from hair at a notably lower concentration than found in other methods (e.g., urine or saliva), making hair drug testing a challenging methodology.
Verification of any positive Screening result is through GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples undergo washing before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
