Hair analysis has emerged as a potent method for identifying substance and alcohol abuse. Hair strands capture biomarkers over time, which reflect a long-term record of alcohol and drug use. When collected near the scalp, hair can reveal drug and alcohol consumption for up to about three months. Hair collection is straightforward, rather tamper-resistant, and convenient for transportation.
A 1.5-inch hair sample, containing roughly 200 strands (comparable to a #2 pencil's diameter), and weighing 100mg, is optimal for both screening and verifying results. For tests like EtG, additional panels, or those exceeding 10 panels, 150mg of hair is advisable. It's suggested to use a jeweler’s scale for weighing. In the absence of scalp hair, a similar amount of body hair is acceptable. References to head hair pertain solely to scalp hair. Body hair entails all other hair categories (facial, axillary, etc.).
Process Overview
The drug test procedure at the laboratory involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of entering a sample into the system. This step ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody.
Screening is a preliminary process that quickly checks for drug abuse. Although Screening is an economical approach for dismissing drug use in most samples, a positive result requires confirmation for legal acceptance. All preliminary positive samples in Screening necessitate further confirmation.
Should a sample test presumptively positive in Screening, additional hair is taken from the primary sample and readied for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging process to execute.
Confirmation of any positive Screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a wash before confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
