Hair evaluations have emerged as an effective mechanism for uncovering alcohol and drug consumption. Hair encapsulates a prolonged record of substance use by capturing biomarkers within the strands as they grow. When clipped near the scalp, hair can reveal substance usage for a duration of up to 90 days. Hair collection is straightforward, somewhat resistant to tampering, and convenient for transport.
A hair sample measuring 1.5 inches and consisting of approximately 200 strands (around the thickness of a #2 pencil) nearest to the scalp will yield 100mg, which is the optimal quantity for testing. For assessments like EtG, extensions, and/or tests exceeding 10 panels, a quantity of 150mg is advisable. We suggest measuring the sample on a jeweler’s scale. Should scalp hair be scant, a similar volume of body hair is permissible. When referencing head hair, we imply only scalp hair. Conversely, body hair pertains to all other hair varieties (facial, axillary, etc.).
Process Overview
The primary phases in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen into a lab’s system. It encompasses confirming the sample’s integrity in terms of sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not available via an electronic chain of custody system.
Screening provides an initial rapid appraisal for drug presence. Although Screening efficiently eliminates drug presence in most samples, a positive outcome requires Verification to meet legal standards. Any samples with preliminary positive results in Screening necessitate a subsequent confirmatory test.
When a sample yields a presumptively positive result in Screening, additional hair from the existing specimen is collected and readied for Extraction. At this phase, the extraction of drugs from hair occurs at a notably lower concentration compared to alternative methods (such as urine or oral fluid), rendering hair drug screening a more intricate procedure.
Verification of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with preliminary positive outcomes undergo a cleaning process before Verification as required. The comprehensive laboratory process, from Accessioning to Verification, is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
