Employing hair analysis has emerged as an effective means for identifying substance and alcohol consumption. Hair serves as a record for long-term substance history by encasing biomarkers within the developing hair shaft. When gathered near the root, hair can offer close to a 3-month period for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch sample consisting of around 200 hair strands (equivalent to a #2 pencil’s thickness) taken nearest to the root will yield 100mg of hair, the perfect sample for assessment and validation. For EtG, additional tests, and/or evaluations exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale to measure the sample is recommended. If head hair is not present, a similar quantity of body hair may be gathered. When discussing head hair, it refers specifically to scalp hair. Body hair pertains to all other hair forms (facial, underarm, etc.).
Process Overview
The laboratory handling of a drug test encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary submission of a sample into a laboratory system. This process verifies that the sample is properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data tasks absent from an electronic custody chain system.
Screening executes an initial swift inspection for illicit substances. Although Screening is a cost-efficient strategy to dismiss drug involvement in most cases, a positive screen must be validated to hold up in legal proceedings. Any samples tentatively positive in Screening need a subsequent confirmation.
If a sample is tentatively positive in Screening, additional hair is extracted from the initial sample for Extraction. During this phase, drugs are separated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug tests particularly complex to conduct.
Verification of any positive Screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS technologies. All preliminary positive specimens are cleansed prior to confirmation as warranted. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
