Hair testing is regarded as a significant method for identifying drug and alcohol consumption. Hair offers an extensive timeline of alcohol and drug patterns by embedding biomarkers within the growing hair shaft. When taken near the scalp, hair can offer close to a three-month detection period for both alcohol and drugs. Gathering hair is easy, challenging to tamper with, and straightforward to transport.
A 1.5-inch segment consisting of around 200 hair strands (about the thickness of a #2 pencil) nearest the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, or panels beyond 10, a sample of 150mg is advisable. Using a jeweler’s scale for weighing is recommended. If scalp hair is lacking, an equivalent quantity of body hair can be utilized. When specified as head hair, it refers only to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).
Process Overview
There are four primary phases in the lab processing of a drug test which are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a laboratory's system. This includes ensuring the sample’s seal and shipment are intact, creating a unique LAN (Laboratory Accessioning Number), and performing any supplemental data entry not available through an electronic tracking system.
Screening conducts a preliminary rapid assessment for potential drug abuse. Though Screening offers a cost-efficient means to eliminate drug presence in many samples, positive findings must be confirmed for legality. Any samples that are initially positive in Screening require further confirmation.
When a sample tests positive in the Screening phase, additional hair is retrieved from the original sample for Extraction. Here, drugs are isolated from the hair at lower concentrations compared to other techniques (such as urine or saliva), making hair drug screening the most labor-intensive method to carry out.
Verification of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing if necessary. The complete laboratory pipeline from Accessioning to Confirmation is assessed under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
