Hair testing is widely viewed as a significant method for identifying drug and alcohol usage. Hair captures biomarkers in the fibers of the developing hair strand, offering a long-term record of alcohol and other drugs. Hair collected close to the scalp can provide up to a 3-month window for detecting alcohol and other substances. It's easy to collect, relatively hard to tamper with, and straightforward to ship.
A 1.5-inch section of about 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, an optimal amount for screening and confirmation. For EtG, add-ons, or panels beyond 10, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn't available, an equivalent quantity of body hair can be collected. By head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of processing a sample into the lab's system. This involves ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any other data entry not already provided by an electronic chain of custody.
Screening involves a preliminary check for drugs of abuse. While Screening is cost-effective for ruling out drug use in most samples, a confirmed positive is essential for court admissibility. Any samples that are presumptively positive in Screening must undergo further confirmation.
If a sample shows a presumptive positive at the Screening step, more hair is taken from the original sample and prepared for Extraction. In Extraction, drugs are removed from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.
Confirmation for any positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as needed. The full laboratory journey from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
