Hair testing has emerged as a robust instrument for identifying drug and alcohol usage. Hair captures a prolonged history of substances by embedding biomarkers in the fibers of the expanding hair strand. When taken from near the scalp, hair can offer up to a 3-month period of detection for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp provides 100mg of hair, deemed the optimal amount for both screening and confirmation. For EtG assessments, additional testing, and/or evaluations exceeding 10 panels, 150mg of the sample is preferred. We advise measuring the sample using a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair can be obtained. When referring to head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial handling of a specimen into a laboratory's system, including verifying the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and conducting any auxiliary data entry absent from an electronic chain of custody system.
Screening consists of an initial rapid test for drugs of abuse. While Screening is a cost-effective means to eliminate drug use in most cases, a positive screen necessitates confirmation to be legally valid. Any samples preliminarily positive in Screening require further confirmation.
If a sample tests presumptively positive at the Screening phase, additional hair is extracted from the original sample for the Extraction phase. In this phase, drugs are removed from hair at significantly lower concentrations than in other methods (like urine or oral fluid), making hair drug screening the most complex technique to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed to be positive are washed before confirmation if required. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
