The assessment of hair provides a thorough method for identifying substance consumption. Hair accumulates biomarkers within its fibers as it grows, offering a comprehensive timeline of alcohol and narcotic intake. When sourced from near the scalp, hair can reveal drug and alcohol use within an estimated three-month frame. The collection process for hair is straightforward, with minimal tampering risk, and it is also conveniently transportable.
A hair sample measuring 1.5 inches with roughly 200 strands (comparable to the thickness of a #2 pencil) from near the scalp yields about 100mg, which is optimal for both inspection and validation. For EtG, additional components, and tests involving more than 10 panels, a specimen of 150mg is advisable. Utilizing a jeweler’s scale for precise specimen weight is recommended. In instances where scalp hair cannot be collected, a similar quantity of body hair may suffice. References to head hair pertain solely to scalp hair, while body hair encompasses all other types, including facial and axillary hair.
Process Overview
The laboratory processing of a drug test consists of four essential phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample transitions into a lab’s system, involving confirmation of the sample’s proper sealing and shipment, allocation of a random LAN (Laboratory Accessioning Number), and completion of any missing data entry absent from an electronic chain of custody system.
Screening performs an initial expedited evaluation for potential substance abuse. Though it offers a budget-conscious means of eliminating drug use suspicions for most samples, a positive result during Screening necessitates confirmation to be legally admissible. Any samples yielding positive presumptive results during Screening require additional verification.
When a sample shows a presumptive positive result in Screening, more hair is extracted from the initial collection and prepared for the Extraction phase. During this phase, substances are separated from hair in significantly smaller concentrations than in methods such as urine or oral fluids, underscoring the complexity of conducting hair drug screening.
Positive Screening outcomes are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation when necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and abides by the ISO / IEC 17025 accreditation standards.
