Hair testing is recognized as a significant method for identifying drug and alcohol consumption. Hair retains a prolonged history of alcohol and other substances by encasing biomarkers within its growing fibers. When collected near the scalp, hair offers nearly a 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment consisting of about 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of the specimen is advised. Using a jeweler's scale is suggested for weighing the specimen. If head hair isn't accessible, a similar quantity of body hair can be used. References to head hair specifically mean scalp hair only. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The core phases in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a lab's system. It validates that the sample was correctly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not covered by an electronic chain of custody system.
Screening provides an initial rapid assessment for drug abuse. Although Screening is a budget-friendly approach for excluding drug usage on most samples, a positive result needs confirmation to be considered valid in legal settings. Samples that screen positive require a further confirmation step.
If a sample initially tests positive in Screening, additional hair from the initial sample is used for Extraction. At this stage, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of a positive screening result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that presumptively screen positive are washed before confirmation if necessary. The full laboratory process from Accessioning through Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
