Hair analysis is recognized as a robust mechanism for identifying drug and alcohol consumption. Hair archives a prolonged record of alcohol and drug usage by embedding biomarkers within the fibers of the maturing hair shaft. When procured near the scalp, hair can offer up to roughly a 90-day discovery frame for alcohol and drugs. Hair procurement is straightforward, relatively challenging to falsify, and convenient to transport.
A sample measuring 1.5 inches, comprising approximately 200 hair strands (akin to the dimension of a #2 pencil) nearest to the scalp, will yield 100mg of hair, the optimal sample for analysis and validation. For EtG, additional testing, and/or when exceeding 10 panels, 150mg of the hair specimen is advised. We suggest utilizing a jeweler’s scale for specimen measurement. If scalp hair isn't present, a comparable amount of body hair may be utilized. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other hair categories (facial, axillary, etc.).
Process Overview
The drug testing laboratory processing entails four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initializing a sample into a lab's system. This process includes checking the sample’s seal and proper shipment, assigning a LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening involves a preliminary rapid assessment for substance abuse. While Screening is a cost-efficient way to detect drug consumption in the bulk of samples, a positive result requires confirmation to be valid legally. Any samples with a presumptive positive in Screening mandate a secondary verification.
If a sample registers presumptively positive in Screening, additional hair is extracted from the initial sample and prepped for Extraction. This step involves deriving drugs from hair at much lower concentrations than in other methods (such as urine or oral fluid), which is why hair drug screening stands as the most complex methodology to conduct.
Confirmation for any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. The comprehensive lab process from Accessioning to Confirmation undergoes a review under the CAP (College of American Pathologists) Hair specification and the accreditation to ISO / IEC 17025 standards.
