Hair examinations are increasingly recognized as an effective means for identifying alcohol and drug usage. Hair captures a detailed record of such substances by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal drug and alcohol consumption for a period extending up to three months. Gathering hair samples is straightforward, they're resistant to tampering, and easily shipped.
A hair sample measuring 1.5 inches, consisting of approximately 200 strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg, which is optimal for analysis. For EtG extensions and/or assessments beyond 10 panels, a 150mg sample is preferred. It's advisable to measure specimens using a jeweler’s scale. If scalp hair is inaccessible, a comparable quantity of body hair may be used. "Head hair" strictly pertains to scalp hair, while "body hair" includes all other forms (such as facial and axillary hair).
Process Overview
Drug test result processing in the lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, incorporating a sample into the lab’s system. This process verifies the sample's proper sealing and shipping, assigns a Laboratory Accessioning Number (LAN) at random, and completes any missing data entry that an electronic custody system might not provide.
Screening provides an initial assessment for substance misuse. While this economical step dismisses drug usage for most cases, a positive screen mandates confirmation to be legally valid. Samples with presumptive positives during Screening require subsequent confirmation.
When a sample yields a presumptive positive in the Screening phase, additional hair is extracted for the Extraction step. Drugs are isolated from hair at notably lower concentrations than alternative methods (such as urine or saliva testing), making hair drug screening uniquely challenging.
Positive screen results undergo Confirmation via techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples are cleansed prior to confirmation if necessary. The entire pathway, from Accessioning through Confirmation, adheres to both CAP (College of American Pathologists) Hair designation criteria and ISO / IEC 17025 accreditation standards.
