Hair testing is recognized as an influential means for uncovering drug and alcohol consumption. Hair records a prolonged history of substance use by encasing biomarkers in the strands of hair as they grow. When retrieved near the scalp, hair may reveal up to a three-month detection span for alcohol and drugs. Hair is easy to gather, somewhat hard to tamper with, and simple to transport.
A 1.5-inch segment of about 200 hairs (a size akin to a #2 pencil) from the scalp yields 100mg of hair, the prime sample for screening and verification. For EtG, add-ons, or analyses exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler's scale to weigh the sample. If scalp hair isn't available, a corresponding quantity of body hair may be taken. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This process involves confirming that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and carrying out additional data input omitted by an electronic chain of custody system.
Screening offers a preliminary rapid review for drug abuse. Though Screening is a cost-efficient means to exclude drug use in most samples, a positive result must be confirmed to be valid in legal proceedings. Samples that preliminarily yield a positive result in Screening need further confirmation.
If a sample preliminarily indicates positivity during Screening, extra hair is extracted from the original sample and prepped for Extraction. In this phase, drugs are drawn out from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the toughest method to execute.
The affirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are cleaned before confirmation as required. The whole lab procedure from Accessioning to Confirmation is assessed per the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.
