Hair testing is increasingly recognized as a robust method for identifying drug and alcohol use. By concentrating biomarkers in the hair's growing fibers, hair offers a comprehensive record of substance use. When collected near the scalp, hair can reveal up to around a 3-month timeframe for detecting alcohol and other drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.
A segment of 1.5 inches comprising roughly 200 hair strands (approximating the size of a #2 pencil) near the scalp provides 100mg of hair, the preferred sample for both screening and confirmation. For EtG, additional tests, and/or evaluations exceeding 10 panels, a 150mg specimen is advisable. We suggest weighing the sample with a jeweler's scale. If scalp hair isn't available, an equivalent quantity of body hair can be used. By head hair, we mean scalp hair exclusively. Body hair includes any other hair types (facial, axillary, etc.).
Process Overview
The primary stages in processing a laboratory drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial intake of a sample into a laboratory’s framework. This process verifies proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not accounted for by an electronic chain of custody system.
Screening is a preliminary rapid assessment for drug abuse. While Screening offers a cost-efficient means to exclude drug usage for most samples, a confirmed positive screen is essential for legal admissibility. Samples with tentative positives from Screening necessitate further confirmation.
For samples tentatively positive in the Screening phase, additional hair is retrieved from the original specimen and prepped for Extraction. During this phase, substances are withdrawn from hair at a markedly lower concentration compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Confirming any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if necessary. The complete laboratory workflow from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
