Hair testing is increasingly recognized as an effective method for identifying drug and alcohol usage. Hair can provide an extended history of alcohol and drugs by capturing biomarkers within the fibers of the hair strand as it grows. When taken near the scalp, hair can offer up to about a 90-day detection period for alcohol and other substances. It's easy to collect, relatively difficult to tamper with, and simple to ship.
A 1.5-inch section of around 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is advised. It's recommended to weigh the sample on a jeweler’s scale. If scalp hair is not accessible, a comparable amount of body hair can be gathered. When referencing head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary steps in the laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a sample into the laboratory's system. This step verifies that the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not available through an electronic chain of custody system.
Screening entails a prompt initial check for drugs of abuse. While Screening is economical in excluding drug usage from most samples, a positive screen must be confirmed for court admissibility. Samples that are preliminarily positive in Screening necessitate further confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is taken from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at a lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug testing is among the most challenging methodologies to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. Samples with presumptive positive results are washed before confirmation as needed. The entire laboratory procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
