The utilization of hair testing has emerged as an effective approach for identifying drug and alcohol consumption. Hair offers an extended review of alcohol and drugs by capturing biomarkers within the expanding hair fibers. A sample cut near the scalp provides an approximate 3-month timeframe for detecting alcohol and drugs. Hair sampling is straightforward, challenging to tamper with, and simple to transport.
An optimal screening and confirmation sample involves a 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) situated closest to the scalp, yielding 100mg. For EtG, special tests, or panels exceeding 10, a 150mg specimen is suggested. Using a jeweler’s scale is advised for specimen weighing. If scalp hair is lacking, a corresponding quantity of body hair can be collected. The term "head hair" solely refers to scalp hair. In contrast, "body hair" encompasses all alternative hair types (facial, axillary, etc.).
Process Overview
The drug test result processing comprises four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the introduction of a sample into the laboratory system. This phase includes validation of proper sealing and shipping of the sample, allocation of a random LAN (Laboratory Accessioning Number), and fulfillment of any missing data entry, apart from what is provided via an electronic chain of custody.
Screening serves as a preliminary examination for drugs of abuse. While it effectively eliminates drug usage in many samples cost-efficiently, a positive screen must be confirmed to be legally valid. Samples showing presumptive positivity necessitate further confirmation.
If a sample indicates presumptive positivity during Screening, additional hair is extracted from the original specimen for the Extraction process. At this stage, drugs are retrieved from hair at minimal concentrations compared to other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples marked as presumptive positive undergo washing as required. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation.
