Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and various drugs by encapsulating biomarkers within the strands of the developing hair. When collected near the scalp, hair can reveal a detection timeline extending up to roughly three months for alcohol and other drugs. It is easy to gather, relatively hard to tamper with, and straightforward to transport.
A sample of hair measuring 1.5 inches and comprising about 200 strands (comparable to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimum sample for both screening and confirmation. For EtG, additional tests, and/or tests that exceed 10 panels, 150mg of the specimen is advisable. We advocate the specimen's measurement on a jeweler’s scale. If scalp hair cannot be obtained, a similar quantity of body hair might be collected. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test outcome in the lab comprises four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab’s system. This process checks the proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any remaining data entry not handled by an electronic chain of custody system.
Screening involves a preliminary assessment for drug abuse. Although Screening is a cost-efficient method to eliminate drug use on most samples, a positive screening must be confirmed to hold up in court. Any samples showing a presumptive positive during Screening require further confirmation.
Should a sample indicate a presumptive positive during the Screening phase, additional hair is extracted from the initial sample and processed for Extraction. Here, drugs are isolated from hair at a much lower concentration than in other methodologies (e.g., urine or oral fluid), contributing to the challenge of hair drug screening processes.
Confirmation of any positive screening outcomes is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before Confirmation if necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
