Hair testing has emerged as a significant means for identifying drug and alcohol consumption. Hair offers prolonged evidence of substance use by embedding biomarkers in the strands of hair as it grows. When sourced near the scalp, hair can reveal up to a 3-month window of detection for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches consisting of about 200 strands of hair (roughly the thickness of a #2 pencil) near the scalp yields approximately 100mg of hair, which is the optimal amount for analysis and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. We suggest measuring the sample using a jeweler’s scale. If scalp hair is insufficient, an equivalent amount of body hair can be gathered. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other forms (facial, axillary, etc.).
Process Outline
The core phases in the lab analysis of drug test results comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a specimen into a lab’s system. It involves confirming that the specimen was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and entering any supplementary data not included by an electronic chain of custody system.
Screening entails an initial rapid assessment for substance abuse. Though Screening is a cost-efficient approach to exclude drug usage in most specimens, a positive screen must be substantiated to be valid in court. Samples that test presumptively positive in Screening need further confirmation.
When a sample is presumptively positive during the Screening phase, more hair is extracted from the original specimen and readied for Extraction. At this stage, drugs are removed from hair at much lower concentrations than in alternate methodologies (e.g., urine or saliva), making hair drug screening one of the most complex methodologies to execute.
Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are cleansed prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is inspected under the CAP (College of American Pathologists) Hair division and holds accreditation according to ISO / IEC 17025 standards.
