Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. The strands of hair retain biomarkers within their fibers, offering a comprehensive history of alcohol and drug presence. When obtained from the scalp, hair can reveal consumption patterns within a 3-month timeframe for various substances. Collecting hair is straightforward, hard to tamper with, and convenient for transport.
A 1.5-inch segment comprising roughly 200 hair strands (comparable to a #2 pencil's thickness) near the scalp yields 100mg of hair, ideal for analysis. For EtG, additional tests, or assessments beyond 10-panel tests, 150mg of hair is advised. A jeweler's scale is suggested for precise measurement. If scalp hair is unavailable, a similar amount of body hair may be used. When discussing head hair, it specifically refers to scalp hair. "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is first integrated into the lab's system. This involves ensuring proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody.
Screening entails an initial assessment for substance abuse. Although Screening provides a cost-effective means to dismiss drug use in the majority of cases, a positive result mandates confirmation for legal acceptance. Samples yielding a presumptive positive require a follow-up assessment.
If a presumptive positive is identified in Screening, additional hair is sourced from the initial sample for the Extraction stage. During Extraction, drugs are isolated from hair at lower concentrations than in other methods (e.g., urine or oral fluid), explaining why hair drug analysis is more challenging.
Confirmation of any positive findings is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if required. The complete lab process, from Accessioning through Confirmation, is scrutinized under CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite being termed as "hair follicle tests," the analysis targets the hair strand rather than the follicle beneath the scalp.
