Hair analysis is increasingly regarded as a robust method for identifying substance and alcohol consumption. Hair offers a lengthy record of alcohol and drug intake by capturing biomarkers within the strands' fibers. When harvested near the scalp, hair can present up to a three-month window for detecting alcohol and drugs. The collection process is straightforward, relatively resistant to tampering, and convenient for shipping.
A 1.5-inch segment comprising approximately 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the preferred sample size for screening and verification. For EtG, add-ons, and/or examinations exceeding 10 panels, a specimen of 150mg is advised. To ensure precision, measuring the specimen on a jeweler’s scale is suggested. Should scalp hair be unavailable, an equivalent volume of body hair might be gathered. It's crucial to distinguish: head hair refers specifically to scalp hair alone, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The key stages in processing a lab drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's framework. This covers verifying the proper sealing and shipment of the sample, generating an arbitrary LAN (Laboratory Accessioning Number), and completing any supplementary data entry not included by an electronic custody chain system.
Screening involves a preliminary rapid assessment for drug abuse. While it's a budget-friendly approach to exclude drug use in most samples, a positive initial screen mandates confirmation for legal validity. Any samples exhibiting presumptive positives in Screening necessitate secondary verification.
If presumptive positivity is indicated during Screening, additional hair is extracted from the initial sample and prepped for Extraction. At this stage, drugs are isolated from hair at much reduced concentrations than in other techniques (e.g., urine or oral fluids), making hair drug testing the most challenging method to execute.
Confirmation of any positive screen result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The complete lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and is in line with ISO / IEC 17025 standards.
