The utilization of hair testing has established itself as a potent means for unveiling drug and alcohol consumption patterns. Hair fibers ensnare biomarkers related to drugs and alcohol throughout their growth, offering an extended historical view. When samples are secured near the scalp, they can reveal substance use over a span of approximately three months. The process of collecting hair is straightforward, hard to tamper with, and easy to transport.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands—the thickness of a #2 pencil—yields 100mg, which is optimal for screening and verification purposes. For tests such as EtG or those exceeding 10 panels, it is advised to obtain 150mg. Using a jeweler's scale for specimen weighing is suggested. If scalp hair is unattainable, a comparable quantity of body hair can be collected. The term "head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The drug test laboratory workflow comprises four pivotal procedures: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into the lab’s system, encompassing confirmation of the intact shipment, assignment of a unique LAN (Laboratory Accessioning Number), and inputting any additional data absent from an electronic chain of custody.
Screening offers a rapid preliminary assessment for substances of abuse. Though cost-effective, a positive result in Screening necessitates confirmation for judicial validity. Samples indicating potential positive results during Screening must undergo further verification.
For samples deemed potentially positive at the Screening stage, additional hair is extracted for the Extraction process. This step involves extracting drugs at much lower concentrations than those found in urine or oral fluid, highlighting the complexity of performing hair drug screening.
Confirmation for any screening results indicating positivity is performed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Samples predicted to be positive undergo washing before Confirmation, if necessary. The comprehensive lab procedures, from Accessioning to Confirmation, adhere to CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 standards.
