Hair analysis has evolved as an effective mechanism for identifying drug and alcohol consumption. It offers an extended historical account of substance use by encasing biomarkers within the hair's burgeoning fibers. Obtaining hair from near the scalp can yield an approximate 3-month window for detecting drugs and alcohol. Hair is straightforward to gather, resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (equivalent to a #2 pencil's thickness) near the scalp provides 100mg of hair, considered the optimal sample for both screening and verification. For testing such as EtG, add-ons, and those exceeding 10 panels, 150mg is advised. A jeweler's scale is recommended for weighing the specimen. If scalp hair isn't available, a similar quantity of body hair can be collected. Reference to head hair pertains exclusively to scalp hair, whereas body hair includes other hair types (e.g., facial, armpits).
Process Overview
The primary steps in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the first processing stage where a sample enters the laboratory system. It encompasses ensuring proper sealing and shipping of the sample, assigning a LAN (Laboratory Accessioning Number), and doing any extra data entry missing from an electronic chain of custody system.
Screening serves as an initial fast assessment for substance abuse. Though it's a cost-efficient approach to eliminate drug use in most samples, a positive result in Screening requires verification for legal admissibility. Samples presumed positive in Screening need secondary confirmation.
When a sample tests presumptively positive in Screening, additional hair is extracted from the initial sample for the Extraction phase. During this phase, chemicals are extracted from hair at much lower concentrations than with other methods (such as urine or saliva), making hair drug testing the most complex methodology to execute.
Positive screening results undergo confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation if necessary. The entire procedure from Accessioning to Confirmation is subject to review under the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.
