Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and substances by encasing biomarkers within the fibers of the progressively growing hair strand. When samples are taken near the scalp, hair can offer around a 3-month window of detection for both alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (akin in size to a #2 pencil) nearest the scalp will yield 100mg of hair, which serves as the optimal sample for both preliminary examination and verification. For EtG, supplemental tests, or evaluations exceeding 10 panels, a 150mg sample is advised. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is lacking, an equivalent amount of body hair can be procured. When mentioning head hair, it pertains exclusively to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample’s initial integration into the laboratory's system. This step ensures that the sample was correctly sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and fulfills any supplementary data entry absent from an electronic chain of custody system.
Screening conducts an introductory swift examination for substances of abuse. While Screening is an economically efficient way to eliminate drug use in most samples, any positive result needs confirmation to be legally viable. Samples with presumptive positive results in Screening necessitate an additional confirmation.
If a sample tests presumptive positive during Screening, additional hair is extracted from the original specimen and prepped for Extraction. In this phase, drugs are isolated from hair at considerably lower concentrations than other techniques (such as urine or oral fluid), which highlights the complexity of hair drug screening.
Positive Screening outcomes undergo confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is scrutinized according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
