Hair analysis has emerged as a robust method for identifying alcohol and drug consumption. Hair captures a comprehensive history of alcohol and drug intake by embedding biomarkers within the hair's fibers as it grows. When samples are taken near the scalp, they can reveal alcohol and drug use for up to 90 days. Hair is straightforward to collect, relatively tamper-proof, and convenient for shipping.
A sample measuring 1.5 inches with approximately 200 hair strands (similar to a #2 pencil) near the scalp provides 100mg, the optimal amount for both screening and validation. For EtG, additional assays, or tests beyond 10 panels, a 150mg sample is advisable. It's beneficial to measure the specimen using a jeweler's scale. If scalp hair isn't available, a comparable quantity of body hair may be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Procedure Summary
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial processing of a sample into a lab's system. This step ensures the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not found in an electronic chain of custody system.
Screening performs an initial rapid evaluation for drug use. While Screening is a cost-effective means to dismiss drug use in most samples, a positive screen must be validated to stand in court. Any samples that appear positive during Screening require additional confirmation.
If a sample suggests positivity in the Screening phase, more hair is extracted from the initial sample and readied for Extraction. In this process, drugs are isolated from hair at lower concentrations than in other methods (e.g. urine or oral fluid), which makes hair drug screening the most challenging procedure to execute.
Confirmation of any positive screening outcome is accomplished using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation when necessary. The full lab process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
