Hair analysis is increasingly recognized as an effective instrument for identifying drug and alcohol consumption. Hair serves as a historical record for substances by encapsulating biomarkers within the strands as they grow. When hair is collected near the scalp, it can reveal drug or alcohol use over an estimated three-month timeframe. The collection process is straightforward, it's relatively tamper-proof, and it's convenient for transport.
A 1.5-inch section, consisting of roughly 200 hair strands (comparable in size to a #2 pencil) nearest the scalp, yields 100mg—ideal for basic and advanced screening procedures. For EtG, supplemental, and/or tests exceeding 10 panels, 150mg of hair is advised. It's beneficial to weigh the sample using a jeweler's scale. If scalp hair isn't available, equivalent body hair can be used. References to head hair specifically mean scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test samples encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, involving the introduction of the sample into the laboratory workflow. This step ensures the sample was appropriately sealed and transported, assigns an LAN (Laboratory Accessioning Number), and finalizes any pending data entry not covered by electronic chain of custody systems.
Screening serves as an initial casual assessment to identify potential drug use. While it's an economical way to eliminate drug users in many cases, positive results require confirmation to be legally valid. Samples suggesting positivity in this phase must undergo secondary confirmation.
Should results from the Screening show presumed positivity, additional hair is drawn from the initial sample for the Extraction phase. Here, substance extraction occurs at concentrations much lower compared to other methods (e.g., urine or oral fluid), underlining the complexity of hair drug analysis.
Confirmation for any initial positive results is done using methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation if necessary. The entire sequence from Accessioning to Confirmation is examined under the guidelines of CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
