Hair analysis emerges as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the strands as they grow. When extracted near the scalp, hair can reveal a detection period extending up to nearly three months for alcohol and drugs. The collection is straightforward, moderately hard to tamper with, and simple to transport.
A 1.5-inch section featuring about 200 hairs (comparable to a #2 pencil) nearest to the scalp provides 100mg of hair, representing the ideal quantity for assessment and verification. For EtG, additions, or assessments beyond 10 panels, 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. In cases where scalp hair is absent, a similar amount of body hair can be utilized. When mentioning head hair, it specifically means scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The key phases in a lab’s treatment of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the first stage of processing a sample into a lab's system. This phase confirms the proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any pending data entry absent in an electronic custody system.
Screening entails a fast assessment of drug misuse. While effective in determining drug-free samples for most cases, a positive result from Screening necessitates validation to stand in court. Any specimens with a presumptive positive in Screening need further confirmation.
In case the Screening identifies a presumptive positive, further hair is retrieved from the initial batch and readied for Extraction. In this step, drug content is extracted at a significantly low concentration than in other methods (such as urine or oral fluid), which makes hair drug testing one of the most challenging techniques to execute.
Verification of any positive from Screening occurs through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positives are cleansed before confirmation as required. The complete lab procedure from Accessioning to Confirmation receives examination under both the CAP (College of American Pathologists) Hair norm and the ISO / IEC 17025 accreditation.
