Hair testing is widely recognized as an effective method for detecting drug and alcohol consumption. Hair captures markers within its fibers, offering a long-term record of alcohol and drug intake. Collected near the scalp, hair can provide a detection timeframe of roughly 3 months for drugs and alcohol. Hair is easy to collect, hard to tamper with, and straightforward to transport.
A 1.5-inch section comprising about 200 hair strands, roughly the thickness of a no. 2 pencil, close to the scalp yields approximately 100mg, the optimal amount for both screening and confirmation. For EtG, additional tests, or when exceeding 10 panels, a 150mg sample is advisable. We suggest weighing the specimen using a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be used. When referencing head hair, we mean only scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The process in the lab for yielding a drug test result consists of four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of initially entering a sample into a lab's system. This step ensures the sample was sealed and sent correctly, assigns a unique LAN (Laboratory Accessioning Number), and finishes any extra data input not part of an electronic chain of custody system.
Screening is a preliminary, quick assessment for drugs of abuse. Although Screening is a cost-efficient means to eliminate drug use for most samples, any positive result must be validated to be legally admissible. Any samples tentatively positive in Screening require further confirmation.
Should a sample test positive in the Screening stage, additional hair is extracted from the initial sample for Extraction. In Extraction, drugs are separated from hair at significantly lower concentrations than other methods (like urine or oral fluid), which makes hair drug testing particularly challenging to perform.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples that preliminarily tested positive are washed, as needed. The entirety of the lab process, from Accessioning to Confirmation, follows the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.
