Hair examination is now regarded as a significant instrument for uncovering drug and alcohol ingestion. Hair captures a lengthy timeline of alcohol and narcotics by ensnaring biomarkers within the strands of growing hair. When taken near the scalp, hair can deliver about a 3-month window for detecting alcohol and drugs. Hair is straightforward to obtain, relatively tamper-resistant, and simple to transport.
A sample of 1.5 inches with approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the prime sample for tests and validation. For EtG additions, and/or analyses exceeding 10 panels, 150mg of hair is suggested. We advocate using a jeweler’s scale to measure the specimen. In the absence of scalp hair, a comparable quantity of body hair can be gathered. When we refer to head hair, it pertains only to scalp hair. Body hair denotes all other types of hair (e.g., facial, axillary).
Process Overview
The four essential steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample into a lab’s system. This encompasses confirming the sample was sealed and dispatched correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and finishing any remaining data entry absent from an electronic chain of custody system.
Screening entails a preliminary rapid evaluation for substance abuse. Though Screening serves as a cost-efficient means to eliminate drug usage for most samples, a positive screen necessitates confirmation for legal admissibility. Any samples that test positive in Screening indeed require further confirmation.
If a sample shows a positive indication in the Screening phase, additional hair is withdrawn from the original specimen and made ready for Extraction. During Extraction, drugs are drawn out from hair at a much finer concentration than other methodologies (such as urine or oral fluids), illustrating why hair drug screenings are notably challenging procedures.
Affirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if necessary. The complete laboratory protocol from Accessioning to Confirmation sustains review under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
