Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a chronological record of substances by locking biomarkers within the fibers of the hair strand as it grows. When sourced close to the scalp, hair can reveal up to a three-month window of detection for alcohol and drugs. Collecting hair is straightforward, somewhat challenging to tamper with, and simple to transport.
A hair segment of 1.5 inches comprising roughly 200 strands (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for testing and confirmation. For EtG, supplementary tests, and/or analyses beyond 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair may be obtained. When mentioning head hair, it pertains strictly to scalp hair. Body hair refers to all other types (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial intake of a specimen into a lab’s system. This step includes checking that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data required not provided by an electronic chain of custody system.
Screening is a preliminary assessment for substances of abuse. Although Screening is a cost-efficient means to dismiss drug usage in the majority of samples, a positive screening result must be confirmed for legal admissibility. Any samples that show presumptive positives in Screening necessitate further confirmation.
Should a sample show a presumptive positive during Screening, further hair from the initial specimen is used for Extraction. In Extraction, drugs are retrieved from hair at much lower concentrations as compared to other methodologies (e.g., urine or oral fluid), making hair drug screening one of the toughest methodologies to conduct.
Confirmation for any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The entire lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair credential and the ISO / IEC 17025 standards accreditation.
