Hair analysis has emerged as an impactful method for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of alcohol and drug use by ensnaring biomarkers within the filaments of the hair as it grows. When procured near the scalp, hair can offer up to a roughly 3-month detection span for alcohol and drugs. It is straightforward to obtain, challenging to tamper with, and convenient to send.
A 1.5-inch segment comprising approximately 200 hair strands (comparable in size to a #2 pencil) closest to the scalp yields 100mg of hair, the optimum amount for assessment and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. Using a jeweler's scale to weigh the specimen is suggested. If scalp hair is absent, an equivalent quantity of body hair can be acquired. When mentioning head hair, it refers exclusively to scalp hair. Body hair is inclusive of all other hair types (facial, axillary, etc.).
Process Overview
The primary phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory's system. This embraces confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing further data entry not supplied by an electronic chain of custody system.
Screening entails a preliminary rapid check for drugs of abuse. Though Screening is a budget-friendly means to dismiss drug presence in the majority of instances, a positive screening requires confirmation to be court admissible. Any samples indicating a presumptive positive during Screening demand secondary confirmation.
Suppose a sample indicates a presumptive positive during the Screening process, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are drawn from hair at considerably lower concentrations than in alternative methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging methodology to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as deemed necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
