Hair testing is now recognized as a crucial method for identifying drug and alcohol consumption. Hair offers a prolonged history of substances by entrapping biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can reveal up to a 3-month detection window for alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment containing roughly 200 strands of hair (similar to the width of a #2 pencil) closest to the scalp yields 100mg, the optimal amount for both initial and confirmatory testing. For EtG, additional screenings, and/or analyses exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair may be used. When referencing head hair, it pertains solely to scalp hair. Body hair refers to any other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial integration into a laboratory system. This encompasses verifying the sample’s proper sealing and shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening involves a preliminary swift assessment for substance abuse. While cost-effective for excluding drug use in most samples, a positive screen must be validated for court admissibility. Any samples with a presumptive positive in Screening require further corroboration.
If a sample tests presumptively positive during the Screening phase, additional hair is drawn from the original sample for Extraction. During this phase, drugs are extracted from hair at significantly reduced concentrations than those found in other matrices (e.g., urine or oral fluid), making hair drug screening the most complex methodology.
Confirmation of any positive screen result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 accreditation.
