Hair testing has become recognized as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged history of substance use by embedding biomarkers in the fibers of the developing hair shaft. When cut near the scalp, hair can offer about a 3-month timeframe for detecting alcohol and drugs. The collection of hair is straightforward, hard to tamper with, and simple to transport.
A 1.5-inch segment consisting of around 200 hair strands (akin to the thickness of a #2 pencil) that is nearest to the scalp will yield 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, supplementary tests, and tests exceeding 10 panels, 150mg of the sample is advised. It is advisable to weigh the sample using a jeweler's scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be used. By head hair, we specifically mean scalp hair. Body hair refers to any other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results comprises four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This includes ensuring the sample was correctly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not covered by an electronic chain of custody procedure.
Screening is a preliminary rapid evaluation for substances of abuse. While Screening is an economical method to dismiss drug usage in most samples, a positive outcome necessitates confirmation to be valid in court. All samples that are initially positive in Screening require subsequent confirmation.
Should a sample suggestively test positive during the Screening phase, additional hair is extracted from the initial sample and set for Extraction. In this phase, substances are extracted from hair at much lower levels than in other processes (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. Any samples suspected as positive are cleansed prior to confirmation if required. The entire lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
