Hair analysis has emerged as an impactful method for identifying drug and alcohol consumption. Hair archives a prolonged history of alcohol and drug intake by encasing biomarkers within the strands of hair as they grow. When cut near the scalp, hair can offer up to a 3-month span for detecting alcohol and drugs. It is easy to gather, somewhat resistant to tampering, and simple to transport.
A 1.5-inch segment consisting of around 200 hair strands (approximately the diameter of a #2 pencil) located nearest to the scalp will yield 100mg of hair, the optimal quantity for examination and corroboration. For EtG, supplementary tests, and/or assessments exceeding 10 panels, 150mg of the sample is advised. It's best to weigh the sample on a jeweler’s scale. If scalp hair isn't available, the same volume of body hair might be taken. When mentioning head hair, it specifically refers to scalp hair. Body hair denotes all other hair kinds (facial, axillary, etc.).
Process Overview
The main four stages involved in the lab handling of a drug testing result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initiation of processing a sample into a lab's system, ensuring the sample's seal and correct shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing supplementary data entry not addressed by an electronic chain of custody system.
Screening is a preliminary quick assessment for substance abuse. While Screening is a pocket-friendly method to rule out drug intake in most samples, a positive result requires confirmation for legal acceptability. Any samples showing presumptive positivity in Screening need further confirmation.
If a sample reveals presumptive positivity in the Screening phase, additional hair is taken from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at far lower concentrations compared to other methodologies (like urine or oral fluid), demonstrating why hair drug testing is the most challenging technique to execute.
Confirmation of any Screening positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show presumptive positivity undergo washing before confirmation as necessary. The entire lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair categorization and the certification to ISO / IEC 17025 standards.
