Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair retains a prolonged record of substance use by embedding biomarkers within the growing hair strand. When procured near the scalp, it can reveal drug and alcohol presence across a roughly 3-month period. Hair collection is straightforward, tough to tamper with, and convenient for transport.
An ideal sample involves a 1.5-inch segment of about 200 hair strands near the scalp, equivalent to #2 pencil thickness, yielding 100mg of hair for screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale to weigh the specimen. In the absence of scalp hair, a comparable quantity of body hair can be gathered. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses other types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test encompasses four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample’s initiation into a lab's system, verifying proper sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing any pending data entry not managed by an electronic chain of custody system.
Screening is a preliminary check for substances of abuse. While cost-efficient for ruling out drug use on most samples, any positive Screening results must be confirmed for court admissibility. Presumptively positive samples do necessitate a secondary confirmation.
For samples with presumptive positivity in Screening, additional hair is taken from the original sample and readied for Extraction. This phase involves extracting drugs from hair at notably lower concentrations compared to other methods (like urine or oral fluid), marking hair drug screening as the most challenging to execute.
Confirmation of any positive screen result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if necessary. The laboratory process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
