Hair testing is recognized as a significant method for discovering drug and alcohol consumption. Hair retains a prolonged record of both alcohol and drugs by encasing biomarkers within the fibers of the developing hair strand. If collected near the scalp, hair can offer nearly a 3-month timeframe for detecting alcohol and drugs. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
A sample of 1.5 inches consisting of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for screening and validation. For EtG, add-ons, and/or examinations surpassing 10 panels, 150mg of the sample is advisable. We advocate measuring the sample on a jeweler’s scale. If scalp hair is lacking, an equivalent quantity of body hair may be collected. "Head hair" refers to scalp hair exclusively. "Body hair" encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is processed into the laboratory’s system. This step entails verifying the proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid evaluation for the presence of drugs of abuse. While it’s an economical method to eliminate drug usage in most samples, a positive screen must be confirmed for court admissibility. Any samples that show a presumptive positive in Screening require a follow-up confirmation.
If a sample exhibits a presumptive positive in Screening, additional hair is extracted from the initial sample for Extraction. During this stage, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening a complex methodology to execute.
The Confirmation of any positive screening outcomes is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as necessary. The entire process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
