Hair analysis has emerged as an effective method for detecting substance use. Hair serves as a chronological record of alcohol and other drug consumption by embedding biomarkers in the structure of the hair shaft. When taken near the scalp, hair can offer up to a roughly three-month detection period for alcohol and other drugs. Collecting hair is straightforward, somewhat resistant to tampering, and convenient for transportation.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the optimal specimen for testing and verifying. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. It's advisable to weigh the hair using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be used. Here, head hair specifically means scalp hair, while body hair encompasses all other hair categories (facial, underarm, etc.).
Process Overview
The lab processing of a drug test result encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen within a laboratory's framework. This phase ensures the sample is appropriately sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data input missing from an electronic chain of custody protocol.
Screening provides an initial rapid evaluation for substance abuse. While Screening is cost-efficient for negating drug use in most cases, a confirmed positive result is necessary for legal acceptance. Any samples that yield a presumptive positive during Screening must undergo further confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. In this stage, substances are isolated from hair at a notably lower concentration relative to other methods (e.g., urine or oral fluid), which is why hair drug testing is notably challenging to execute.
Confirmation of any presumptive positive is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test presumptively positive are washed before confirmation as required. The comprehensive lab process from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
