Hair analysis has established itself as an effective method for identifying drug and alcohol consumption. It provides an extended history of substance use by capturing biomarkers within the fibers of the growing hair shaft. When gathered from near the scalp, hair can offer up to a three-month period for detecting alcohol and other drugs. Hair is easy to collect, quite resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches with around 200 hair strands (comparable to a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for both screening and verification. For EtG assessments, additional screenings, and panels exceeding ten, a 150mg sample is advised. Employing a jeweler’s scale is recommended for weighing the specimen. If scalp hair is not available, an equivalent quantity of body hair can be used. The term "head hair" refers solely to scalp hair, while "body hair" encompasses all other types such as facial and axillary hair.
Process Overview
The laboratory processes a drug test result through four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial steps in integrating a sample into a lab's system, which includes verifying proper sealing and shipping of the sample, assigning a unique Laboratory Accessioning Number (LAN), and completing any additional data entry absent from an electronic chain of custody system.
Screening is a preliminary swift assessment for drug abuse. While it is a cost-effective means for excluding drug usage across most samples, a positive result in screening must be confirmed to be valid in legal proceedings. Any sample that appears positive during Screening requires further confirmation.
For samples showing a presumptive positive during Screening, additional hair is extracted from the primary sample for the Extraction phase. During this step, drugs are extracted from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), posing a challenge for hair drug screening.
Confirmation of a positive screening result is performed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive result are washed as necessary preceding confirmation. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation as well as ISO / IEC 17025 accreditation standards.
