Hair analysis is now considered a significant means for identifying alcohol and drug consumption. Hair captures a historical record of drugs and alcohol by capturing biomarkers in the strands as they grow. Collected close to the scalp, hair testing can reveal up to three months' worth of alcohol and drug use history. The process of collection is straightforward, relatively tamper-proof, and transport-friendly.
A 1.5-inch section comprising around 200 strands (an amount akin to a #2 pencil's width) is ideal, offering 100mg of hair for preliminary and confirmatory analyses. For assessments like EtG, supplements, or tests exceeding 10 panels, a 150mg sample is advised. Measuring the sample with a jeweler's scale is suggested. If scalp hair isn't accessible, a comparable quantity of body hair may suffice. When mentioning head hair, it pertains solely to scalp hair. Conversely, body hair denotes all other variants (facial, axillary, etc.).
Process Overview
The testing laboratory follows four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial handling phase, integrating a sample into the lab's system. This phase verifies sample seal integrity and proper shipment, allocates an arbitrary LAN (Laboratory Accessioning Number), and completes any data entry overlooked by an electronic chain of custody mechanism.
Screening constitutes the initial rapid assessment for drugs of abuse. Although this provides an economical method of excluding drug usage in most samples, a positive screen insists on confirmation for legal admissibility. Samples with presumptive positive results in Screening necessitate subsequent confirmation.
When a sample tests presumptively positive during Screening, additional hair is extracted from the original sample and processed for Extraction. This phase isolates drugs from hair at notably lower concentrations compared to other techniques (e.g., urine or saliva), highlighting hair drug screening's complexity.
Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results undergo washing before confirmation if needed. From Accessioning to Confirmation, the entire lab procedure is scrutinized under both the CAP (College of American Pathologists) Hair directive and ISO / IEC 17025 accreditation.
