Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair offers an extended overview of alcohol and drug usage by encapsulating biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair can offer up to a 3-month detection timeframe for alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment consisting of around 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for testing and confirmation. For EtG, special tests, and/or assessments beyond 10 panels, 150mg is suggested. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an equivalent body hair sample can be used. Head hair refers specifically to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The four key phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, where a sample is integrated into a lab's system. This involves validating that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data not provided by an electronic chain of custody system.
Screening conducts an initial, rapid assessment for drugs of abuse. Though Screening is a low-cost approach to eliminate drug usage on most samples, a positive screen requires confirmation to be court-admissible. Any samples that are preliminarily positive in Screening need a secondary confirmation.
Should a sample be preliminarily 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 much lower concentration than alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening results is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
