Hair analysis has gained recognition as an effective approach for identifying substance and alcohol consumption. Hair offers a detailed history of alcohol and other substances by capturing biomarkers in the filaments of the growing strand. When clipped near the scalp, hair can offer around a 3-month detection span for alcohol and other substances. Collecting hair is straightforward, relatively challenging to tamper with, and convenient for transport.
A 1.5-inch portion consisting of about 200 hair strands (roughly the size of a #2 pencil) positioned nearest to the scalp will supply 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, additional tests, and/or screenings exceeding 10 panels, 150mg of the sample is advised. We propose weighing the sample on a jeweler’s scale. Should scalp hair be unavailable, an equivalent volume of body hair can be used. Referring to head hair implies scalp hair solely. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four primary stages involved in processing drug test outcomes in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. It involves confirming that the sample was sealed and sent correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry omitted by an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient method for eliminating drug use in most samples, a positive screen must be substantiated to hold in a legal context. Any samples that test presumptively positive during Screening require further confirmation.
Should a sample test presumptively positive in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. During this phase, substances are extracted from hair at considerably lower concentrations than in other techniques (such as urine or oral fluid), which is why hair drug screening is notably challenging to undertake.
Confirmation of any positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed as necessary prior to confirmation. The complete lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.
