Hair testing emerges as an influential method for identifying drug and alcohol consumption. Hair captures a long-term profile of substances by embedding biomarkers within the hair's growing strand fibers. When sourced near the scalp, hair offers up to a 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, less prone to tampering, and easily shippable.
A sample consisting of about 200 hair strands (approximately the width of a #2 pencil) measuring 1.5 inches from the scalp yields 100mg, the optimal amount for both screening and confirmation. While analyzing EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is suggested. It is advisable to measure the specimen with a jeweler’s scale. In the absence of scalp hair, an equivalent body hair sample can be obtained. The term head hair specifically pertains to scalp hair, whereas body hair includes all other types (such as facial or axillary).
Process Overview
Four principal phases define the laboratory's process for determining a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial input of a sample into a laboratory’s framework. This step ensures the sample’s seal and shipment integrity, generates a random LAN (Laboratory Accessioning Number), and completes any necessary data input aside from what an electronic chain of custody system provides.
Screening performs an initial, efficient check for substance abuse. While serving as a cost-effective means to eliminate drug use in most samples, a positive Screening outcome requires confirmation to be valid in a legal setting. Any Screening samples deemed presumptive positive necessitate additional confirmation.
If a sample tests presumptive positive during Screening, supplementary hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are recuperated from hair at substantially lower concentrations compared to other techniques (e.g., urine or saliva), making hair drug testing one of the most complex methodologies to conduct.
Confirmation of presumptive positive results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if needed. The comprehensive laboratory workflow from Accessioning to Confirmation undergoes review based on both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
