Hair testing is widely regarded as a valuable method for detecting drug and alcohol consumption. Hair captures a historical record of substance use by embedding biomarkers within the hair strand's fibers as it grows. When collected near the scalp, hair can offer a detection period of up to nearly three months for alcohol and drug exposure. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (about the thickness of a #2 pencil) taken from the area nearest the scalp will yield 100mg of hair, which is the optimal amount for analysis and verification. For EtG, add-ons, or evaluations exceeding 10 panels, a specimen weight of 150mg is advised. We suggest using a jeweler’s scale to measure the specimen's weight. If scalp hair cannot be obtained, an equivalent quantity of body hair can be used. When we mention head hair, we mean scalp hair specifically. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result involves these primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab's system. This stage includes verifying that the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data input not covered by an electronic chain of custody system.
Screening provides an initial rapid assessment for drugs of abuse. Although Screening is a cost-effective method to dismiss drug use for most samples, a positive result requires confirmation to be legally admissible. Samples showing presumptive positivity at Screening necessitate subsequent confirmation.
When a sample exhibits presumptive positivity during Screening, additional hair is taken from the original specimen and prepared for Extraction. In Extraction, drugs are isolated from hair at concentrations significantly lower than those in other methodologies (e.g., urine or oral fluid), making hair drug screening the most complex methodology to perform.
Confirmation for any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation according to ISO / IEC 17025 standards.
