Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair strands retain a long-term record of alcohol and substance use by capturing biomarkers within the fibers as the hair grows. When sourced near the scalp, hair can reflect up to a 3-month detection window for alcohol and drugs. It's easy to gather, relatively tamper-resistant, and straightforward to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp provides about 100mg of hair, which is optimal for screening and verification. For EtG, supplementary tests, and/or assessments beyond 10 panels, a 150mg sample is advisable. Using a jeweler's scale to weigh the specimen is suggested. If scalp hair isn't available, a comparable quantity of body hair may be collected. The term head hair solely refers to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The four primary procedures in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's system. This step verifies the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any extra data entry absent from an electronic chain of custody framework.
Screening performs an initial rapid assessment for substance abuse. While Screening is a cost-efficient approach to eliminate drug use in most samples, a positive result requires confirmation for legal acceptance. Any samples that test presumptively positive during Screening necessitate an additional confirmation.
When a sample tests presumptively positive in the Screening phase, further hair is extracted from the original specimen and prepped for Extraction. In this stage, substances are removed from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive Screening result occurs via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive specimens are cleaned before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair certificate and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly called "hair follicle tests", the exam actually assesses the hair strand, not the follicle beneath the scalp.
