Hair analysis is increasingly recognized as a strong method for uncovering drug and alcohol consumption. It captures long-term substance use data by embedding biomarkers within the hair strand's fibers as it grows. When hair is harvested near the scalp, it can reveal information about drug and alcohol consumption for up to about 90 days. Hair has the advantages of being easy to collect, somewhat resistant to tampering, and straightforward to transport.
A sample of 1.5 inches consisting of around 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp provides 100mg, the perfect amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. Using a jeweler’s scale to weigh the sample is advised. In cases where scalp hair isn't present, a similar quantity of body hair can be obtained. Note that head hair strictly refers to scalp hair alone. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results is primarily comprised of four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into the lab's system, ensuring the sample was sealed and shipped correctly, shouldering a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not managed by an electronic chain of custody system.
Screening acts as a preliminary inspection for drugs of abuse. While it is an economical approach for excluding drug usage in the majority of samples, a positive screen needs verification to be court-valid. Presumptively positive Screening samples necessitate subsequent confirmation.
Should a sample test positive at the Screening step, additional hair is extracted from the original specimen in preparation for Extraction. During Extraction, substances are extracted from hair at a reduced concentration versus other practices (e.g., urine or oral fluid), making hair drug screening a highly challenging practice.
Confirmation of any initial positive result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if needed. The entire laboratory workflow from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair recognition and the ISO/IEC 17025 accreditation.
