Hair examination is increasingly recognized as an effective method for identifying substance and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug usage by retaining biomarkers in the fibers of the hair as it grows. When sourced from near the scalp, hair can present an alcohol and drug detection span of up to three months approximately. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.
A segment of 1.5 inches consisting of nearly 200 hair strands (comparable to a #2 pencil's diameter) from the scalp area yields 100mg, which is the optimal sample size for evaluation and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale is suggested for weighing the sample. Should scalp hair be unavailable, an equivalent volume of body hair may be used. When discussing head hair, it solely pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is integrated into a laboratory’s system. This process includes ensuring that the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry absent from an electronic chain of custody system.
Screening serves as a preliminary rapid assessment for substance abuse. Although Screening is an economical means to reject drug use in most samples, any positive screen must be confirmed for court acceptance. Samples suggesting positive results in Screening necessitate further confirmation.
When a sample indicates a presumptive positive in Screening, additional hair is taken from the initial sample and readied for Extraction. In this stage, substances are drawn from hair at a concentration significantly lower than that in other testing methods (such as urine or oral fluid), leading to hair drug screening being the most challenging methodology to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The comprehensive lab process from Accessioning to Confirmation undergoes review according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
