Hair analysis is recognized as an effective means for identifying alcohol and drug consumption. The hair captures a long-term record of alcohol and other substances by embedding biomarkers within the hair shaft as it grows. If gathered near the scalp, hair can offer around a three-month detection timeframe for drugs and alcohol. Hair is straightforward to obtain, relatively challenging to alter, and uncomplicated to transport.
A 1.5-inch section consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for screening and validation. For EtG, supplementary tests, and/or panels beyond ten, collecting 150mg is advised. Utilizing a jeweler’s scale for measuring the specimen is recommended. If scalp hair isn't accessible, a comparable amount of body hair can be used. "Head hair" pertains solely to scalp hair, while "body hair" includes other types (such as facial and axillary hair).
Process Overview
The laboratory procedure for processing a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into a laboratory’s system. This step ensures the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes necessary data entry not available via an electronic chain of custody system.
Screening provides a preliminary assessment for drugs of abuse. Though a cost-efficient method to eliminate drug use in many samples, a positive result in Screening must undergo Confirmation to be valid in legal proceedings. Samples with a presumptive positive outcome in Screening require additional Confirmation.
For samples indicated as presumptive positives in Screening, further hairs are taken from the initial sample for Extraction. This phase involves extracting drugs from hair at much lower concentrations than alternative methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
For Confirmation, any positive results from Screening are validated using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples undergo washing before confirmation, as needed. The entire procedure, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 criteria.
