Hair testing has emerged as a robust method for detecting drug and alcohol consumption. The hair shaft captures biomarkers within its fibers, providing a prolonged history of alcohol and drugs. When sourced close to the head, hair can yield a detection period of up to about 3 months for various substances. Collection is straightforward, tampering is quite challenging, and it is easy to transport.
A 1.5-inch hair sample of roughly 200 strands (comparable to the thickness of a #2 pencil) nearest the head yields 100mg, which is suitable for screening and verification. For EtG, additional testing, or assessments beyond 10 panels, a specimen of 150mg is advised. Using a jeweler’s scale to measure the specimen is recommended. If scalp hair is absent, a similar quantity of body hair can be used. References to head hair imply scalp hair solely, while body hair denotes other hair types (facial, axillary, etc.).
Process Overview
The four primary steps in laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample's preliminary processing within a lab's system. It ensures proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.
Screening entails an initial swift assessment for substance abuse. While it is a cost-efficient method to rule out drug usage for most samples, any positive screen needs confirmation to be acceptable in legal settings. Presumptive positive samples in screening necessitate additional confirmation.
For samples deemed presumptive positives during Screening, more hair is extracted from the initial sample for Extraction. This phase involves removing drugs from hair at significantly lower concentrations than other methods (like urine or oral fluid), making hair drug testing the most demanding methodology.
GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive screen results. Required presumptive positive samples undergo washing before confirmation. The entire process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
