Hair sample analysis has emerged as a robust mechanism for identifying the usage of drugs and alcohol. Hair records a prolonged timeline of alcohol and various drugs by embedding biomarkers within the fibers of the developing hair strand. When collected in proximity to the scalp, hair offers close to a 3-month detection period for alcohol and other substances. It is straightforward to gather, relatively hard to tamper with, and simple to send.
A 1.5-inch portion of roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp produces 100mg of hair, which is the optimum amount for both screening and confirmation. For EtG, additional tests, and/or tests over 10 panels, a 150mg specimen is advisable. We suggest weighing the sample on a jeweler's scale. If scalp hair is not an option, a comparable volume of body hair could be used. In terms of head hair, we reference only scalp hair. Body hair signifies all other types (facial, axillary, etc.).
Process Overview
The principal stages in the lab processing of a drug testing result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves commencing the processing of a sample into the lab's system. This step consists of checking that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any other data input not covered by an electronic chain of custody system.
Screening performs an initial swift check for substances of abuse. While Screening offers a cost-efficient means to dismiss drug use in most samples, a positive screen must be verified for courtroom validity. Any samples preliminarily positive in Screening necessitate a follow-up confirmation.
In the event a sample is initially flagged positive during Screening, additional hair is removed from the original specimen and readied for Extraction. Here, drugs are extracted from hair at a notably lower concentration than through other techniques (e.g., urine or oral fluid), hence why hair drug screening is the most challenging technique to execute.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as preliminarily positive undergo washing before confirmation, as needed. The full laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
