Hair analysis is acknowledged as a significant means for uncovering drug and alcohol consumption. Hair can deliver an elongated timeline of substance use by capturing markers within the growing strand's fibers. When obtained near the scalp, hair can present nearly a 3-month analysis timeframe for alcohol and other substances. Hair acquisition is straightforward, challenging to taint, and simple to distribute.
A sample measuring 1.5 inches, comprising approximately 200 hair strands (parallel to a #2 pencil's girth) adjacent to the scalp, equals 100mg - the perfect quantity for evaluation. For EtG, additional tests, and/or more than 10 panel assessments, 150mg of the material is advisable. Utilizing a jeweler’s scale for measurement is suggested. If scalp hair is unobtainable, an equivalent portion of body hair may be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory evaluation of a drug test incorporates four essential procedures: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the primary introduction of a specimen into a lab's system. This process includes confirming the specimen's seal and proper shipment, attributing a random Laboratory Accessioning Number (LAN), and finalizing any outstanding data entries not completed through an electronic custody chain system.
Screening involves an initial rapid assessment for substances of abuse. Although Screening serves as a budget-friendly approach for ruling out substance usage in most specimens, a positive screen requires confirmation to be legally valid. Screening-identifiable presumptive positives mandate a follow-up confirmation.
Upon obtaining a presumptive positive during Screening, additional hair from the original sample is procured and readied for Extraction. At this phase, drugs are extracted from hair at markedly lower concentrations than other methodologies (e.g., urine or oral fluid), rendering hair drug testing the most complex method to conduct.
Confirmation for any positive Screening outcome takes place via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives undergo necessary washing before confirmation. The entire laboratory route from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair title and compliance with ISO / IEC 17025 standards.
