Hair evaluations have gained recognition as an influential method for identifying drug and alcohol intake. Hair offers a prolonged record of substances by capturing markers within the fibers of the emerging hair strand. When procured near the scalp, hair can present up to roughly a three-month detection period for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A sample measuring 1.5 inches consisting of around 200 hair strands (about the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, a prime quantity for both screening and confirmation. For EtG, additional analyses, and/or examinations beyond 10 panels, 150mg is suggested. It is advisable to use a jeweler’s scale to weigh the sample. In case scalp hair isn’t available, a comparable amount of body hair could be collected. Reference to head hair implies scalp hair only, while body hair encompasses all other hair types (such as facial or axillary hair).
Process Overview
The process of generating a drug test result in a laboratory entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about initially integrating a sample into the lab's system. This phase includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drugs of abuse. While cost-effective for excluding drug presence in numerous samples, a positive screening outcome necessitates confirmation for legal acceptance. Samples with presumptive positives in Screening require further verification.
For Screening-stage presumptive positives, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), making hair drug evaluation the most challenging to execute.
Confirmation of any positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation as needed. The comprehensive laboratory workflow from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
