Hair analysis is regarded as an effective instrument for detecting alcohol and drug use. This method offers a comprehensive history of substance consumption by confining biomarkers within the strands of hair as they grow. Collected near the scalp, hair can supply a detection timeframe of up to three months for alcohol and drugs. The collection process is straightforward, the likelihood of tampering is minimal, and it is simple to ship.
A sample size of 1.5 inches with roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp provides 100mg of hair, perfect for both screening and confirmation processes. For EtG, additional tests, or when testing exceeds 10 panels, a specimen of 150mg is advised. Duely, weighing the sample on a jeweler’s scale is suggested. If scalp hair isn't present, comparable body hair may be utilized. When discussing head hair, it strictly refers to scalp hair, while body hair comprises all other categories (such as facial, axillary).
Process Overview
The primary phases in the laboratory processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s database. This procedure involves ensuring the sample was correctly sealed and sent, attaching a random LAN (Laboratory Accessioning Number), and completing any surplus data input absent from an electronic chain of custody framework.
Screening serves as a preliminary check for substance abuse. Although it's a budget-friendly method for excluding drug use in most samples, positive screenings need validation for court admissibility. Presumptive positive samples from Screening require an additional confirmation test.
When a Screening result is presumptive positive, further hair is drawn from the initial sample and set for Extraction. Here, drugs are isolated from hair at significantly lower levels than other approaches (like urine or oral fluids), highlighting why hair drug analysis is the most intricate method.
GC/MS, GC/MS/MS, or LC/MS/MS methods are employed to confirm any positive screening findings. Prior to confirmation, presumptive positive samples are cleansed as necessary. Every aspect of the laboratory procedure from Accessioning to Confirmation is thoroughly evaluated under CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.
