Hair analysis has gained recognition as an effective approach for uncovering drug and alcohol consumption. Hair captures long-term indicators of alcohol and drugs by securing biomarkers in the structure of the developing hair shaft. When taken near the scalp, hair can offer a nearly 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively challenging to tamper with, and simple to transport.
A 1.5-inch segment comprising around 200 strands of hair (roughly the width of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal quantity for both screening and confirmation. When testing for EtG, additional analyses, and/or panels exceeding 10, a specimen of 150mg is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair is not available, an equivalent volume of body hair may be gathered. References to head hair are specific to scalp hair alone, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The main procedural stages in the lab analysis of a drug test sample encompass four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial handling of a specimen within a lab’s framework. This step ensures the sample was properly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent from an electronic chain of custody system.
Screening constitutes a preliminary evaluation for substances of abuse. Although Screening offers a cost-efficient method to negate drug use across most samples, positive results require confirmation to be legally accepted. Samples yielding a presumptive positive in Screening must undergo an additional confirmatory test.
In cases of a presumptive positive in the Screening phase, extra hair is extracted from the initial sample for the Extraction stage. During Extraction, drugs are isolated from hair at concentrations notably lower than those in comparable methods (e.g., urine or oral fluid), making hair drug testing the most challenging technique to administer.
Any positive results from Screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as necessary. The complete laboratory evaluation, from Accessioning to Confirmation, undergoes review according to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
