Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive history of alcohol and drug exposure by encapsulating biomarkers within the strands as they grow. When hair is sampled near the scalp, it can provide a detection period of up to three months for alcohol and other drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.
A sample of 1.5 inches comprising roughly 200 hair strands (around the diameter of a #2 pencil) near the scalp yields approximately 100mg, which is the optimal weight for analysis and verification. For EtG, additional tests, or panels exceeding 10, it is advisable to obtain 150mg of the specimen. A jeweler’s scale is recommended for weighing the specimen. If scalp hair is unavailable, an equivalent quantity of body hair can be utilized. The term "head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
Processing a drug test result in the lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the preliminary processing of a sample into a lab’s workflow. This step includes ensuring the sample was correctly sealed and sent, assigning it a randomized LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody system.
Screening comprises an initial rapid assessment for substance abuse. While it is a cost-efficient method for dismissing drug use in most specimens, any positive result during Screening must be confirmed for legal admissibility. Presumptive positives from Screening necessitate a secondary validation.
In cases where a sample tests presumptively positive in Screening, more hair is retrieved from the initial batch and prepared for Extraction. At this juncture, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug testing poses a greater challenge in execution.
Confirming positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process, from Accessioning through to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
