Hair analysis has emerged as a substantial resource for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of alcohol and drugs by embedding biomarkers within the fibers of the developing hair strand. When retrieved near the scalp, hair can reveal up to an estimated 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment consisting of around 200 strands of hair (roughly equivalent to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimum sample for both screening and verification. For EtG, supplemental testing, or examinations exceeding 10 panels, 150mg of the specimen is advised. It's suggested to use a jeweler’s scale for weighing the specimen. If scalp hair is not available, a comparable amount of body hair may be gathered. "Head hair" specifies only scalp hair, whereas "body hair" includes all other hair types (facial, axillary, etc.).
Process Overview
The principal steps in the laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within a lab’s framework. This process confirms that the specimen was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and addresses any further data entry missing from an electronic chain of custody system.
Screening offers an initial assessment for drugs of misuse. Although Screening provides a cost-efficient method to exclude drug use in most samples, a positive screen needs validation to stand in legal proceedings. Samples that show presumptive positivity in Screening require further confirmation.
If a sample emerges as presumptively positive during Screening, additional hair is taken from the initial collection and engineered for Extraction. This phase involves drugs being drawn from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), rendering hair drug screening the most intricate methodology to execute.
Confirmation of any positive screened results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are cleaned as necessary before confirmation. The complete lab procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the accreditation under ISO / IEC 17025 standards.
