Hair analysis is now recognized as a potent method for identifying drug and alcohol consumption. Hair retains a prolonged record of substance use by encapsulating biomarkers within the hair fiber. When cut close to the scalp, hair can reveal substance use insights for up to an estimated 90-day period. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches from about 200 hairs (similar in size to a #2 pencil) nearest to the scalp yields 100mg—the optimal amount for initial testing and confirmation. For EtG, additional evaluations, and tests exceeding 10 panels, a specimen of 150mg is advised. It's best to weigh the sample with a jeweler’s scale. If scalp hair isn't available, a comparable volume of body hair might be gathered. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory process for a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory’s system. This crucial phase involves confirming the sample's secure sealing and proper shipment, issuing a random LAN (Laboratory Accessioning Number), and entering any additional data not added by an electronic chain of custody.
Screening is a preliminary evaluation for drugs of abuse. As a budget-conscious method to identify non-use in the majority of samples, a positive screen still requires confirmation for court validity. Samples indicating a presumptive positive in Screening need further confirmation.
If the Screening stage suggests a presumptive positive result, additional hair is extracted from the provided sample for Extraction. In this phase, drugs are removed from hair at significantly reduced concentrations compared to methods like urine or oral fluid, highlighting the difficulty of performing hair drug screening.
Verification of any positive screening result is executed via techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Samples preliminarily positive are cleansed prior to confirmation as deemed necessary. The comprehensive lab process from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
