Hair analysis has emerged as an effective means for identifying drug and alcohol usage. Hair retains a prolonged record of alcohol and other substances by incorporating biomarkers into the strands as they grow. When trimmed near the scalp, hair can indicate substance presence for up to roughly a 90-day timeframe. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
A 1.5-inch sample comprising about 200 hair strands (approximately the width of a #2 pencil) adjacent to the scalp yields 100mg of hair, the optimal amount for evaluation and validation. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of hair is advisable. Utilizing a jeweler’s scale for measuring the sample is recommended. In the absence of scalp hair, a similar quantity of body hair can be utilized. References to head hair specifically pertain to scalp hair. Body hair encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The primary phases in laboratory processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary integration of a sample into a laboratory’s framework. This phase involves ensuring the sample is sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data not provided by an electronic chain of custody system.
Screening pertains to an initial cursory examination for illicit drug presence. While Screening is an economical method to exclude drug consumption in most samples, a positive screen mandates validation for court admissibility. Samples indicating a presumptive positive in Screening necessitate a secondary affirmation.
When a sample registers presumptively positive during Screening, additional hair is sourced from the primary sample and prepped for Extraction. At this juncture, drugs are extracted from hair at a considerably lower concentration than other methods (such as urine or oral fluid), rendering hair drug analysis the most complex method to execute.
Affirmation of any positive screening outcome is pursued through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positivity are cleansed prior to confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation standards.
